GIT-REV-LIST(1) 		   Git Manual			 GIT-REV-LIST(1)

NAME
     git-rev-list - Lists commit objects in reverse chronological order

SYNOPSIS
     git rev-list [<options>] <commit>... [--] [<path>...]

DESCRIPTION
     List  commits  that  are  reachable  by following the parent links from the
     given commit(s), but exclude commits that are  reachable  from  the  one(s)
     given with a ^ in front of them. The output is given in reverse chronologi-
     cal order by default.

     You can think of this as a set operation. Commits reachable from any of the
     commits  given  on  the command line form a set, and then commits reachable
     from any of the ones given with ^ in front are subtracted	from  that  set.
     The  remaining  commits are what comes out in the command's output. Various
     other options and paths parameters can be used to further limit the result.

     Thus, the following command:

	 $ git rev-list foo bar ^baz

     means "list all the commits which are reachable from foo or  bar,	but  not
     from baz".

     A	special  notation "<commit1>..<commit2>" can be used as a short-hand for
     "^<commit1> <commit2>". For example, either of the following  may	be  used
     interchangeably:

	 $ git rev-list origin..HEAD
	 $ git rev-list HEAD ^origin

     Another  special  notation  is  "<commit1>...<commit2>" which is useful for
     merges. The resulting set of commits is the  symmetric  difference  between
     the two operands. The following two commands are equivalent:

	 $ git rev-list A B --not $(git merge-base --all A B)
	 $ git rev-list A...B

     rev-list  is  an  essential  Git  command, since it provides the ability to
     build and traverse commit ancestry graphs. For this reason, it has a lot of
     different options that enable it to be used by commands as different as git
     bisect and git repack.

OPTIONS
   Commit Limiting
     Besides specifying a range of commits that should be listed using the  spe-
     cial notations explained in the description, additional commit limiting may
     be applied.

     Using   more   options   generally   further   limits   the   output  (e.g.
     --since=<date1> limits to commits newer than <date1>,  and  using	it  with
     --grep=<pattern>  further	limits	to  commits whose log message has a line
     that matches <pattern>), unless otherwise noted.

     Note that these are applied before commit ordering and formatting	options,
     such as --reverse.

     -<number>, -n <number>, --max-count=<number>
	 Limit the output to <number> commits.

     --skip=<number>
	 Skip <number> commits before starting to show the commit output.

     --since=<date>, --after=<date>
	 Show commits more recent than <date>.

     --since-as-filter=<date>
	 Show  all  commits  more recent than <date>. This visits all commits in
	 the range, rather than stopping at the first commit which is older than
	 <date>.

     --until=<date>, --before=<date>
	 Show commits older than <date>.

     --max-age=<timestamp>, --min-age=<timestamp>
	 Limit the commits output to specified time range.

     --author=<pattern>, --committer=<pattern>
	 Limit the commits output to ones  with  author/committer  header  lines
	 that  match  the <pattern> regular expression. With more than one --au-
	 thor=<pattern>, commits whose author matches any of the  <pattern>  are
	 chosen (similarly for multiple --committer=<pattern>).

     --grep-reflog=<pattern>
	 Limit	the  commits  output  to ones with reflog entries that match the
	 <pattern> regular expression. With more than one --grep-reflog, commits
	 whose reflog message matches any of the given patterns are  chosen.  It
	 is an error to use this option unless --walk-reflogs is in use.

     --grep=<pattern>
	 Limit	the  commits  output to ones with a log message that matches the
	 <pattern> regular expression. With more than one --grep=<pattern>, com-
	 mits whose message matches any of the <pattern>  are  chosen  (but  see
	 --all-match).

     --all-match
	 Limit	the  commits output to ones that match all given --grep, instead
	 of ones that match at least one.

     --invert-grep
	 Limit the commits output to ones with a log message that do  not  match
	 the <pattern> specified with --grep=<pattern>.

     -i, --regexp-ignore-case
	 Match the regular expression limiting patterns without regard to letter
	 case.

     --basic-regexp
	 Consider the limiting patterns to be basic regular expressions; this is
	 the default.

     -E, --extended-regexp
	 Consider  the	limiting patterns to be extended regular expressions in-
	 stead of the default basic regular expressions.

     -F, --fixed-strings
	 Consider the limiting patterns to be  fixed  strings  (don't  interpret
	 pattern as a regular expression).

     -P, --perl-regexp
	 Consider  the	limiting  patterns to be Perl-compatible regular expres-
	 sions.

	 Support for these types of regular  expressions  is  an  optional  com-
	 pile-time dependency. If Git wasn't compiled with support for them pro-
	 viding this option will cause it to die.

     --remove-empty
	 Stop when a given path disappears from the tree.

     --merges
	 Print only merge commits. This is exactly the same as --min-parents=2.

     --no-merges
	 Do  not  print  commits  with more than one parent. This is exactly the
	 same as --max-parents=1.

     --min-parents=<number>,	  --max-parents=<number>,      --no-min-parents,
     --no-max-parents
	 Show  only  commits  which  have at least (or at most) that many parent
	 commits. In particular, --max-parents=1 is  the  same	as  --no-merges,
	 --min-parents=2  is  the  same  as --merges.  --max-parents=0 gives all
	 root commits and --min-parents=3 all octopus merges.

	 --no-min-parents and --no-max-parents reset these limits (to no  limit)
	 again.  Equivalent  forms are --min-parents=0 (any commit has 0 or more
	 parents) and --max-parents=-1 (negative numbers denote no upper limit).

     --first-parent
	 When finding commits to include, follow only the  first  parent  commit
	 upon seeing a merge commit. This option can give a better overview when
	 viewing the evolution of a particular topic branch, because merges into
	 a topic branch tend to be only about adjusting to updated upstream from
	 time  to time, and this option allows you to ignore the individual com-
	 mits brought in to your history by such a merge.

     --exclude-first-parent-only
	 When finding commits to exclude (with a ^), follow only the first  par-
	 ent commit upon seeing a merge commit. This can be used to find the set
	 of  changes in a topic branch from the point where it diverged from the
	 remote branch, given that arbitrary merges can be  valid  topic  branch
	 changes.

     --not
	 Reverses  the meaning of the ^ prefix (or lack thereof) for all follow-
	 ing revision specifiers, up to the next --not. When used on the command
	 line before --stdin, the revisions passed through stdin will not be af-
	 fected by it. Conversely, when passed via standard input, the revisions
	 passed on the command line will not be affected by it.

     --all
	 Pretend as if all the refs in refs/, along with HEAD, are listed on the
	 command line as <commit>.

     --branches[=<pattern>]
	 Pretend as if all the refs in refs/heads are listed on the command line
	 as <commit>. If <pattern> is given, limit  branches  to  ones	matching
	 given	shell  glob. If <pattern> lacks ?, *, or [, /* at the end is im-
	 plied.

     --tags[=<pattern>]
	 Pretend as if all the refs in refs/tags are listed on the command  line
	 as  <commit>.	If <pattern> is given, limit tags to ones matching given
	 shell glob. If pattern lacks ?, *, or [, /* at the end is implied.

     --remotes[=<pattern>]
	 Pretend as if all the refs in refs/remotes are listed	on  the  command
	 line as <commit>. If <pattern> is given, limit remote-tracking branches
	 to  ones  matching given shell glob. If pattern lacks ?, *, or [, /* at
	 the end is implied.

     --glob=<glob-pattern>
	 Pretend as if all the	refs  matching	shell  glob  <glob-pattern>  are
	 listed on the command line as <commit>. Leading refs/, is automatically
	 prepended if missing. If pattern lacks ?, *, or [, /* at the end is im-
	 plied.

     --exclude=<glob-pattern>
	 Do  not  include  refs  matching  <glob-pattern>  that  the next --all,
	 --branches, --tags, --remotes, or --glob would otherwise consider. Rep-
	 etitions of this option accumulate exclusion patterns up  to  the  next
	 --all,  --branches,  --tags, --remotes, or --glob option (other options
	 or arguments do not clear accumulated patterns).

	 The patterns given should not	begin  with  refs/heads,  refs/tags,  or
	 refs/remotes  when applied to --branches, --tags, or --remotes, respec-
	 tively, and they must begin with refs/ when applied to --glob or --all.
	 If a trailing /* is intended, it must be given explicitly.

     --exclude-hidden=(fetch|receive|uploadpack)
	 Do not include refs that would be hidden by git-fetch, git-receive-pack
	 or git-upload-pack by consulting the  appropriate  fetch.hideRefs,  re-
	 ceive.hideRefs  or  uploadpack.hideRefs configuration along with trans-
	 fer.hideRefs  (see  git-config(1)).  This  option  affects   the   next
	 pseudo-ref option --all or --glob and is cleared after processing them.

     --reflog
	 Pretend  as  if all objects mentioned by reflogs are listed on the com-
	 mand line as <commit>.

     --alternate-refs
	 Pretend as if all objects mentioned as ref tips of alternate  reposito-
	 ries  were  listed  on the command line. An alternate repository is any
	 repository whose object directory is specified  in  objects/info/alter-
	 nates.  The  set  of  included  objects  may be modified by core.alter-
	 nateRefsCommand, etc. See git-config(1).

     --single-worktree
	 By default, all working trees will be examined by the following options
	 when there are more than one (see git-worktree(1)): --all, --reflog and
	 --indexed-objects. This option forces them to examine the current work-
	 ing tree only.

     --ignore-missing
	 Upon seeing an invalid object name in the input, pretend as if the  bad
	 input was not given.

     --stdin
	 In  addition to getting arguments from the command line, read them from
	 standard input as well. This accepts commits  and  pseudo-options  like
	 --all	and --glob=. When a -- separator is seen, the following input is
	 treated as paths and used to limit the result. Flags like  --not  which
	 are  read via standard input are only respected for arguments passed in
	 the same way and will not influence any subsequent command  line  argu-
	 ments.

     --quiet
	 Don't	print  anything to standard output. This form is primarily meant
	 to allow the caller to test the exit status to see if a  range  of  ob-
	 jects is fully connected (or not). It is faster than redirecting stdout
	 to /dev/null as the output does not have to be formatted.

     --disk-usage, --disk-usage=human
	 Suppress  normal  output;  instead, print the sum of the bytes used for
	 on-disk storage by the selected commits or objects. This is  equivalent
	 to   piping  the  output  into  git  cat-file	--batch-check='%(object-
	 size:disk)',  except  that  it  runs  much  faster   (especially   with
	 --use-bitmap-index). See the CAVEATS section in git-cat-file(1) for the
	 limitations  of  what	"on-disk storage" means. With the optional value
	 human, on-disk storage size  is  shown  in  human-readable  string(e.g.
	 12.24 Kib, 3.50 Mib).

     --cherry-mark
	 Like  --cherry-pick  (see  below)  but  mark  equivalent commits with =
	 rather than omitting them, and inequivalent ones with +.

     --cherry-pick
	 Omit any commit that introduces the same change as  another  commit  on
	 the  "other  side"  when  the set of commits are limited with symmetric
	 difference.

	 For example, if you have two branches, A and B, a usual way to list all
	 commits on only one side of them is with --left-right (see the  example
	 below in the description of the --left-right option). However, it shows
	 the commits that were cherry-picked from the other branch (for example,
	 "3rd  on b" may be cherry-picked from branch A). With this option, such
	 pairs of commits are excluded from the output.

     --left-only, --right-only
	 List only commits on the respective side  of  a  symmetric  difference,
	 i.e. only those which would be marked < resp. > by --left-right.

	 For  example, --cherry-pick --right-only A...B omits those commits from
	 B which are in A or are patch-equivalent to a commit  in  A.  In  other
	 words,  this  lists  the + commits from git cherry A B. More precisely,
	 --cherry-pick --right-only --no-merges gives the exact list.

     --cherry
	 A synonym for --right-only --cherry-mark --no-merges; useful  to  limit
	 the output to the commits on our side and mark those that have been ap-
	 plied	to  the other side of a forked history with git log --cherry up-
	 stream...mybranch, similar to git cherry upstream mybranch.

     -g, --walk-reflogs
	 Instead of walking the commit ancestry chain, walk reflog entries  from
	 the  most recent one to older ones. When this option is used you cannot
	 specify commits to exclude (that is,  ^<commit>,  <commit1>..<commit2>,
	 and <commit1>...<commit2> notations cannot be used).

	 With --pretty format other than oneline and reference (for obvious rea-
	 sons),  this  causes  the output to have two extra lines of information
	 taken from the reflog. The reflog designator in the output may be shown
	 as ref@{<Nth>} (where <Nth> is the reverse-chronological index  in  the
	 reflog)  or as ref@{<timestamp>} (with the <timestamp> for that entry),
	 depending on a few rules:

	  1. If the starting point is specified as ref@{<Nth>}, show  the  index
	     format.

	   2. If  the  starting point was specified as ref@{now}, show the time-
	     stamp format.

	  3. If neither was used, but --date was given on the command line, show
	     the timestamp in the format requested by --date.

	  4. Otherwise, show the index format.

	 Under --pretty=oneline, the commit message is prefixed with this infor-
	 mation on the same line. This option cannot be combined with --reverse.
	 See also git-reflog(1).

	 Under --pretty=reference, this information will not be shown at all.

     --merge
	 Show commits touching conflicted paths  in  the  range  HEAD...<other>,
	 where	 <other>   is	the  first  existing  pseudoref  in  MERGE_HEAD,
	 CHERRY_PICK_HEAD, REVERT_HEAD or REBASE_HEAD. Only works when the index
	 has unmerged entries. This option can be used to show relevant  commits
	 when resolving conflicts from a 3-way merge.

     --boundary
	 Output excluded boundary commits. Boundary commits are prefixed with -.

     --use-bitmap-index
	 Try  to  speed  up the traversal using the pack bitmap index (if one is
	 available). Note that when traversing with --objects, trees  and  blobs
	 will not have their associated path printed.

     --progress=<header>
	 Show progress reports on stderr as objects are considered. The <header>
	 text will be printed with each progress update.

     -z
	 Instead  of  being newline-delimited, each outputted object and its ac-
	 companying metadata is delimited using NUL bytes. Output is printed  in
	 the following form:

	     <OID> NUL [<token>=<value> NUL]...

	 Additional  object  metadata, such as object paths or boundary objects,
	 is printed using the <token>=<value> form.  Token  values  are  printed
	 as-is	without any encoding/truncation. An OID entry never contains a =
	 character and thus is used to signal the start of a new object  record.
	 Examples:

	     <OID> NUL
	     <OID> NUL path=<path> NUL
	     <OID> NUL boundary=yes NUL
	     <OID> NUL missing=yes NUL [<token>=<value> NUL]...

	 This  mode  is  only  compatible  with  the  --objects, --boundary, and
	 --missing output options.

   History Simplification
     Sometimes you are only interested in parts of the history, for example  the
     commits  modifying  a particular <path>. But there are two parts of History
     Simplification, one part is selecting the commits and the other is  how  to
     do it, as there are various strategies to simplify the history.

     The following options select the commits to be shown:

     <paths>
	 Commits modifying the given <paths> are selected.

     --simplify-by-decoration
	 Commits that are referred by some branch or tag are selected.

     Note that extra commits can be shown to give a meaningful history.

     The following options affect the way the simplification is performed:

     Default mode
	 Simplifies  the  history  to  the simplest history explaining the final
	 state of the tree. Simplest because it prunes some side branches if the
	 end result is the same (i.e. merging branches with the same content)

     --show-pulls
	 Include all commits from the default mode, but also any  merge  commits
	 that  are  not TREESAME to the first parent but are TREESAME to a later
	 parent. This mode is helpful for showing the merge commits that  "first
	 introduced" a change to a branch.

     --full-history
	 Same as the default mode, but does not prune some history.

     --dense
	 Only  the  selected  commits  are shown, plus some to have a meaningful
	 history.

     --sparse
	 All commits in the simplified history are shown.

     --simplify-merges
	 Additional option to --full-history to remove some needless merges from
	 the resulting history, as there are no selected commits contributing to
	 this merge.

     --ancestry-path[=<commit>]
	 When given a range of commits to display (e.g.  <commit1>..<commit2> or
	 <commit2> ^<commit1>), and a commit <commit> in that range,  only  dis-
	 play  commits in that range that are ancestors of <commit>, descendants
	 of <commit>, or <commit> itself. If no commit is specified,  use  <com-
	 mit1>	(the excluded part of the range) as <commit>. Can be passed mul-
	 tiple times; if so, a commit is included if it is any	of  the  commits
	 given or if it is an ancestor or descendant of one of them.

     A more detailed explanation follows.

     Suppose you specified foo as the <paths>. We shall call commits that modify
     foo  !TREESAME,  and  the	rest TREESAME. (In a diff filtered for foo, they
     look different and equal, respectively.)

     In the following, we will always refer to the same example history  to  il-
     lustrate  the  differences  between simplification settings. We assume that
     you are filtering for a file foo in this commit graph:

		   .-A---M---N---O---P---Q
		  /	/   /	/   /	/
		 I     B   C   D   E   Y
		  \   /   /   /   /   /
		   `-------------'   X

     The horizontal line of history A---Q is taken to be  the  first  parent  of
     each merge. The commits are:

     *	 I  is the initial commit, in which foo exists with contents asdf, and a
	 file quux exists with contents quux. Initial commits are compared to an
	 empty tree, so I is !TREESAME.

     *	 In A, foo contains just foo.

     *	 B contains the same change as A. Its  merge  M  is  trivial  and  hence
	 TREESAME to all parents.

     *	 C  does  not change foo, but its merge N changes it to foobar, so it is
	 not TREESAME to any parent.

     *	 D sets foo to baz. Its merge O combines the strings from  N  and  D  to
	 foobarbaz; i.e., it is not TREESAME to any parent.

     *	 E  changes  quux to xyzzy, and its merge P combines the strings to quux
	 xyzzy.  P is TREESAME to O, but not to E.

     *	 X is an independent root commit that added a new file side, and Y modi-
	 fied it.  Y is TREESAME to X. Its merge Q added side to  P,  and  Q  is
	 TREESAME to P, but not to Y.

     rev-list  walks  backwards  through history, including or excluding commits
     based on whether --full-history and/or parent rewriting (via  --parents  or
     --children) are used. The following settings are available.

     Default mode
	 Commits  are  included  if  they are not TREESAME to any parent (though
	 this can be changed, see --sparse below). If the commit  was  a  merge,
	 and  it  was  TREESAME to one parent, follow only that parent. (Even if
	 there are several TREESAME parents, follow only one  of  them.)  Other-
	 wise, follow all parents.

	 This results in:

		       .-A---N---O
		      /     /	/
		     I---------D

	 Note  how the rule to only follow the TREESAME parent, if one is avail-
	 able, removed B from consideration entirely.  C was considered  via  N,
	 but  is  TREESAME.  Root commits are compared to an empty tree, so I is
	 !TREESAME.

	 Parent/child relations are only visible with --parents, but  that  does
	 not  affect  the commits selected in default mode, so we have shown the
	 parent lines.

     --full-history without parent rewriting
	 This mode differs from the default in one point: always follow all par-
	 ents of a merge, even if it is TREESAME to one of them.  Even	if  more
	 than one side of the merge has commits that are included, this does not
	 imply that the merge itself is! In the example, we get

		     I	A  B  N  D  O  P  Q

	 M was excluded because it is TREESAME to both parents.  E, C and B were
	 all walked, but only B was !TREESAME, so the others do not appear.

	 Note  that  without parent rewriting, it is not really possible to talk
	 about the parent/child relationships between the commits,  so	we  show
	 them disconnected.

     --full-history with parent rewriting
	 Ordinary  commits  are only included if they are !TREESAME (though this
	 can be changed, see --sparse below).

	 Merges are always included. However, their parent  list  is  rewritten:
	 Along each parent, prune away commits that are not included themselves.
	 This results in

		       .-A---M---N---O---P---Q
		      /     /	/   /	/
		     I	   B   /   D   /
		      \   /   /   /   /
		       `-------------'

	 Compare  to  --full-history  without  rewriting  above. Note that E was
	 pruned away because it is TREESAME,  but  the	parent	list  of  P  was
	 rewritten  to	contain E's parent I. The same happened for C and N, and
	 X, Y and Q.

     In addition to the above settings, you can change whether TREESAME  affects
     inclusion:

     --dense
	 Commits  that	are  walked are included if they are not TREESAME to any
	 parent.

     --sparse
	 All commits that are walked are included.

	 Note that without --full-history, this still simplifies merges: if  one
	 of the parents is TREESAME, we follow only that one, so the other sides
	 of the merge are never walked.

     --simplify-merges
	 First,  build	a history graph in the same way that --full-history with
	 parent rewriting does (see above).

	 Then simplify each commit C to its replacement C' in the final  history
	 according to the following rules:

	 *   Set C' to C.

	 *   Replace  each  parent  P  of  C' with its simplification P'. In the
	     process, drop parents that are ancestors of other parents	or  that
	     are  root commits TREESAME to an empty tree, and remove duplicates,
	     but take care to never drop all parents that we are TREESAME to.

	 *   If after this parent rewriting, C' is a root or merge  commit  (has
	     zero  or  >1 parents), a boundary commit, or !TREESAME, it remains.
	     Otherwise, it is replaced with its only parent.

	 The effect of this is best shown by way of comparing to  --full-history
	 with parent rewriting. The example turns into:

		       .-A---M---N---O
		      /     /	    /
		     I	   B	   D
		      \   /	  /
		       `---------'

	 Note the major differences in N, P, and Q over --full-history:

	 *   N's  parent  list	had  I removed, because it is an ancestor of the
	     other parent M. Still, N remained because it is !TREESAME.

	 *   P's parent list similarly had I removed.  P was then  removed  com-
	     pletely, because it had one parent and is TREESAME.

	 *   Q's parent list had Y simplified to X.  X was then removed, because
	     it  was a TREESAME root.  Q was then removed completely, because it
	     had one parent and is TREESAME.

     There is another simplification mode available:

     --ancestry-path[=<commit>]
	 Limit the displayed commits to those which are an ancestor of <commit>,
	 or which are a descendant of <commit>, or are <commit> itself.

	 As an example use case, consider the following commit history:

			 D---E-------F
			/     \       \
		       B---C---G---H---I---J
		      / 		    \
		     A-------K---------------L--M

	 A regular D..M computes the set of commits that are ancestors of M, but
	 excludes the ones that are ancestors of D. This is useful to  see  what
	 happened  to  the history leading to M since D, in the sense that "what
	 does M have that did not exist in D". The result in this example  would
	 be all the commits, except A and B (and D itself, of course).

	 When  we  want  to find out what commits in M are contaminated with the
	 bug introduced by D and need fixing, however, we  might  want	to  view
	 only  the  subset  of D..M that are actually descendants of D, i.e. ex-
	 cluding C and K. This is exactly what the --ancestry-path option  does.
	 Applied to the D..M range, it results in:

			     E-------F
			      \       \
			       G---H---I---J
					    \
					     L--M

	 We  can  also	use  --ancestry-path=D	instead of --ancestry-path which
	 means the same thing when applied to the D..M range but  is  just  more
	 explicit.

	 If  we  instead  are interested in a given topic within this range, and
	 all commits affected by that topic, we may only want to view the subset
	 of D..M which contain that topic in  their  ancestry  path.  So,  using
	 --ancestry-path=H D..M for example would result in:

			     E
			      \
			   C---G---H---I---J
					    \
					     L--M

	 Whereas --ancestry-path=K D..M would result in

			     K---------------L--M

     Before discussing another option, --show-pulls, we need to create a new ex-
     ample history.

     A	common	problem  users face when looking at simplified history is that a
     commit they know changed a file somehow does not appear in the file's  sim-
     plified  history. Let's demonstrate a new example and show how options such
     as --full-history and --simplify-merges works in that case:

		   .-A---M-----C--N---O---P
		  /	/ \  \	\/   /	 /
		 I     B   \  R-'`-Z'	/
		  \   /     \/	       /
		   \ /	    /\	      /
		    `---X--'  `---Y--'

     For this example, suppose I created file.txt which was modified  by  A,  B,
     and  X  in  different  ways.  The	single-parent commits C, Z, and Y do not
     change file.txt. The merge commit M was created by resolving the merge con-
     flict to include both changes from A and B and hence is not TREESAME to ei-
     ther. The merge commit R, however, was created by ignoring the contents  of
     file.txt  at  M  and taking only the contents of file.txt at X. Hence, R is
     TREESAME to X but not M. Finally, the natural merge resolution to create  N
     is  to take the contents of file.txt at R, so N is TREESAME to R but not C.
     The merge commits O and P are TREESAME to their first parents, but  not  to
     their second parents, Z and Y respectively.

     When  using the default mode, N and R both have a TREESAME parent, so those
     edges are walked and the others are ignored. The  resulting  history  graph
     is:

		 I---X

     When  using  --full-history,  Git	walks every edge. This will discover the
     commits A and B and the merge M, but also will reveal the merge  commits  O
     and P. With parent rewriting, the resulting graph is:

		   .-A---M--------N---O---P
		  /	/ \  \	\/   /	 /
		 I     B   \  R-'`--'	/
		  \   /     \/	       /
		   \ /	    /\	      /
		    `---X--'  `------'

     Here, the merge commits O and P contribute extra noise, as they did not ac-
     tually  contribute  a change to file.txt. They only merged a topic that was
     based on an older version of file.txt. This is a common issue in  reposito-
     ries  using  a  workflow where many contributors work in parallel and merge
     their topic branches along a single trunk: many unrelated merges appear  in
     the --full-history results.

     When using the --simplify-merges option, the commits O and P disappear from
     the  results.  This  is because the rewritten second parents of O and P are
     reachable from their first parents. Those edges are removed  and  then  the
     commits  look like single-parent commits that are TREESAME to their parent.
     This also happens to the commit N, resulting in a history view as follows:

		   .-A---M--.
		  /	/    \
		 I     B      R
		  \   /      /
		   \ /	    /
		    `---X--'

     In this view, we see all of the important single-parent changes from A,  B,
     and  X.  We  also	see  the carefully-resolved merge M and the not-so-care-
     fully-resolved merge R. This is usually enough information to determine why
     the commits A and B "disappeared" from history in the  default  view.  How-
     ever, there are a few issues with this approach.

     The  first  issue	is  performance.  Unlike any previous option, the --sim-
     plify-merges option requires walking the entire commit history  before  re-
     turning a single result. This can make the option difficult to use for very
     large repositories.

     The  second issue is one of auditing. When many contributors are working on
     the same repository, it is  important  which  merge  commits  introduced  a
     change  into  an  important  branch.  The	problematic merge R above is not
     likely to be the merge commit that was used  to  merge  into  an  important
     branch.  Instead,	the merge N was used to merge R and X into the important
     branch. This commit may have information about why the  change  X	came  to
     override the changes from A and B in its commit message.

     --show-pulls
	 In  addition  to  the	commits  shown in the default history, show each
	 merge commit that is not TREESAME to its first parent but  is	TREESAME
	 to a later parent.

	 When  a  merge commit is included by --show-pulls, the merge is treated
	 as  if  it  "pulled"  the  change  from  another  branch.  When   using
	 --show-pulls on this example (and no other options) the resulting graph
	 is:

		     I---X---R---N

	 Here,	the  merge  commits R and N are included because they pulled the
	 commits X and R into the base branch, respectively.  These  merges  are
	 the reason the commits A and B do not appear in the default history.

	 When  --show-pulls is paired with --simplify-merges, the graph includes
	 all of the necessary information:

		       .-A---M--.   N
		      /     /	 \ /
		     I	   B	  R
		      \   /	 /
		       \ /	/
			`---X--'

	 Notice that since M is reachable from R, the edge from N to M was  sim-
	 plified  away.  However, N still appears in the history as an important
	 commit because it "pulled" the change R into the main branch.

     The --simplify-by-decoration option allows you to view only the big picture
     of the topology of the history, by omitting commits that are not referenced
     by tags. Commits are marked as !TREESAME (in other words, kept  after  his-
     tory  simplification  rules  described above) if (1) they are referenced by
     tags, or (2) they change the contents of the paths  given	on  the  command
     line.  All  other	commits are marked as TREESAME (subject to be simplified
     away).

   Bisection Helpers
     --bisect
	 Limit output to the one commit object which is roughly halfway  between
	 included and excluded commits. Note that the bad bisection ref refs/bi-
	 sect/bad  is  added to the included commits (if it exists) and the good
	 bisection refs refs/bisect/good-* are added to the excluded commits (if
	 they exist). Thus, supposing there are no refs in refs/bisect/, if

		     $ git rev-list --bisect foo ^bar ^baz

	 outputs midpoint, the output of the two commands

		     $ git rev-list foo ^midpoint
		     $ git rev-list midpoint ^bar ^baz

	 would be of roughly the same length. Finding the  change  which  intro-
	 duces	a regression is thus reduced to a binary search: repeatedly gen-
	 erate and test new 'midpoint's until the commit chain is of length one.

     --bisect-vars
	 This calculates the same as --bisect, except that refs in  refs/bisect/
	 are  not used, and except that this outputs text ready to be eval'ed by
	 the shell. These lines will assign the name of the midpoint revision to
	 the variable bisect_rev, and the  expected  number  of  commits  to  be
	 tested  after bisect_rev is tested to bisect_nr, the expected number of
	 commits to be tested if bisect_rev turns out to be good to bisect_good,
	 the expected number of commits to be tested if bisect_rev turns out  to
	 be  bad to bisect_bad, and the number of commits we are bisecting right
	 now to bisect_all.

     --bisect-all
	 This outputs all the commit objects between the included  and	excluded
	 commits,  ordered  by	their distance to the included and excluded com-
	 mits. Refs in refs/bisect/ are not used. The farthest from them is dis-
	 played first. (This is the only one displayed by --bisect.)

	 This is useful because it makes it easy to choose a good commit to test
	 when you want to avoid to test some of them for some reason  (they  may
	 not compile for example).

	 This  option  can be used along with --bisect-vars, in this case, after
	 all the sorted commit objects, there will be the same text as if  --bi-
	 sect-vars had been used alone.

   Commit Ordering
     By default, the commits are shown in reverse chronological order.

     --date-order
	 Show  no  parents  before  all of its children are shown, but otherwise
	 show commits in the commit timestamp order.

     --author-date-order
	 Show no parents before all of its children  are  shown,  but  otherwise
	 show commits in the author timestamp order.

     --topo-order
	 Show no parents before all of its children are shown, and avoid showing
	 commits on multiple lines of history intermixed.

	 For example, in a commit history like this:

		 ---1----2----4----7
		     \		    \
		      3----5----6----8---

	 where	the  numbers denote the order of commit timestamps, git rev-list
	 and friends with --date-order show the commits in the timestamp  order:
	 8 7 6 5 4 3 2 1.

	 With  --topo-order,  they  would show 8 6 5 3 7 4 2 1 (or 8 7 4 2 6 5 3
	 1); some older commits are shown before newer ones in	order  to  avoid
	 showing the commits from two parallel development track mixed together.

     --reverse
	 Output  the  commits  chosen  to  be shown (see Commit Limiting section
	 above) in reverse order. Cannot be combined with --walk-reflogs.

   Object Traversal
     These options are mostly targeted for packing of Git repositories.

     --objects
	 Print the object IDs of any object referenced by  the	listed	commits.
	 --objects  foo  ^bar thus means "send me all object IDs which I need to
	 download if I have the commit object bar but not foo". See  also  --ob-
	 ject-names below.

     --in-commit-order
	 Print	tree and blob ids in order of the commits. The tree and blob ids
	 are printed after they are first referenced by a commit.

     --objects-edge
	 Similar to --objects, but also print the IDs of excluded  commits  pre-
	 fixed	with  a  "-"  character.  This is used by git-pack-objects(1) to
	 build a "thin" pack, which records objects in deltified form  based  on
	 objects contained in these excluded commits to reduce network traffic.

     --objects-edge-aggressive
	 Similar to --objects-edge, but it tries harder to find excluded commits
	 at  the  cost of increased time. This is used instead of --objects-edge
	 to build "thin" packs for shallow repositories.

     --indexed-objects
	 Pretend as if all trees and blobs used by the index are listed  on  the
	 command line. Note that you probably want to use --objects, too.

     --unpacked
	 Only useful with --objects; print the object IDs that are not in packs.

     --object-names
	 Only  useful with --objects; print the names of the object IDs that are
	 found. This is the default behavior. Note that the "name" of  each  ob-
	 ject  is  ambiguous, and mostly intended as a hint for packing objects.
	 In particular: no distinction is made between the names of tags, trees,
	 and blobs; path names may be modified to remove newlines; and if an ob-
	 ject would appear multiple times with different names, only one name is
	 shown.

     --no-object-names
	 Only useful with --objects; does not print the names of the object  IDs
	 that  are found. This inverts --object-names. This flag allows the out-
	 put to be more easily parsed by commands such as git-cat-file(1).

     --filter=<filter-spec>
	 Only useful with one of the --objects*; omits objects	(usually  blobs)
	 from  the  list of printed objects. The <filter-spec> may be one of the
	 following:

	 The form --filter=blob:none omits all blobs.

	 The form --filter=blob:limit=<n>[kmg] omits blobs of size at least  <n>
	 bytes	or units.  <n> may be zero. The suffixes k, m, and g can be used
	 to name units in KiB, MiB, or GiB. For example,  blob:limit=1k  is  the
	 same as blob:limit=1024.

	 The  form --filter=object:type=(tag|commit|tree|blob) omits all objects
	 which are not of the requested type. Note that explicitly provided  ob-
	 jects	ignore	filters  and  are  always  printed  unless --filter-pro-
	 vided-objects is also specified.

	 The form --filter=sparse:oid=<blob-ish> uses a sparse-checkout specifi-
	 cation contained in the blob (or blob-expression)  <blob-ish>	to  omit
	 blobs that would not be required for a sparse checkout on the requested
	 refs.

	 The  form  --filter=tree:<depth>  omits all blobs and trees whose depth
	 from the root tree is >= <depth> (minimum depth if an object is located
	 at multiple depths in the commits traversed).	<depth>=0 will	not  in-
	 clude any trees or blobs unless included explicitly in the command-line
	 (or  standard input when --stdin is used).  <depth>=1 will include only
	 the tree and blobs which are referenced directly by a commit  reachable
	 from  <commit>  or  an  explicitly-given  object.   <depth>=2	is  like
	 <depth>=1 while also including trees and blobs one more  level  removed
	 from an explicitly-given commit or tree.

	 Note  that the form --filter=sparse:path=<path> that wants to read from
	 an arbitrary path on the filesystem has been dropped for security  rea-
	 sons.

	 Multiple  --filter= flags can be specified to combine filters. Only ob-
	 jects which are accepted by every filter are included.

	 The form --filter=combine:<filter1>+<filter2>+...<filterN> can also  be
	 used  to combined several filters, but this is harder than just repeat-
	 ing the --filter flag and is usually not necessary. Filters are  joined
	 by  +	and individual filters are %-encoded (i.e. URL-encoded). Besides
	 the + and % characters, the following characters are reserved and  also
	 must be encoded: ~!@#$^&*()[]{}\;",<>?'` as well as all characters with
	 ASCII code <= 0x20, which includes space and newline.

	 Other	arbitrary  characters  can  also  be encoded. For instance, com-
	 bine:tree:3+blob:none and combine:tree%3A3+blob%3Anone are equivalent.

     --no-filter
	 Turn off any previous --filter= argument.

     --filter-provided-objects
	 Filter the list of explicitly provided objects, which	would  otherwise
	 always  be  printed even if they did not match any of the filters. Only
	 useful with --filter=.

     --filter-print-omitted
	 Only useful with --filter=; prints a list of the objects omitted by the
	 filter. Object IDs are prefixed with a "~" character.

     --missing=<missing-action>
	 A debug option to help with future "partial  clone"  development.  This
	 option specifies how missing objects are handled.

	 The form --missing=error requests that rev-list stop with an error if a
	 missing object is encountered. This is the default action.

	 The form --missing=allow-any will allow object traversal to continue if
	 a missing object is encountered. Missing objects will silently be omit-
	 ted from the results.

	 The  form --missing=allow-promisor is like allow-any, but will only al-
	 low object traversal to continue for EXPECTED promisor missing objects.
	 Unexpected missing objects will raise an error.

	 The form --missing=print is like allow-any, but will also print a  list
	 of the missing objects. Object IDs are prefixed with a "?"  character.

	 The  form --missing=print-info is like print, but will also print addi-
	 tional information about the missing object inferred from its	contain-
	 ing  object.  The  information is all printed on the same line with the
	 missing object ID in the form: ?<oid>	[<token>=<value>]....  The  <to-
	 ken>=<value> pairs containing additional information are separated from
	 each  other  by a SP. The value is encoded in a token specific fashion,
	 but SP or LF contained in value are always expected to  be  represented
	 in  such a way that the resulting encoded value does not have either of
	 these two problematic bytes. Each <token>=<value> may	be  one  of  the
	 following:

	 *   The  path=<path> shows the path of the missing object inferred from
	     a containing object. A path containing SP or special characters  is
	     enclosed in double-quotes in the C style as needed.

	 *   The  type=<type> shows the type of the missing object inferred from
	     a containing object.

	 If some tips passed to the traversal are missing, they will be  consid-
	 ered  as  missing  too,  and the traversal will ignore them. In case we
	 cannot get their Object ID though, an error will be raised.

     --exclude-promisor-objects
	 (For internal use only.) Prefilter object traversal at promisor  bound-
	 ary.  This  is  used  with partial clone. This is stronger than --miss-
	 ing=allow-promisor because it limits the traversal,  rather  than  just
	 silencing errors about missing objects.

     --no-walk[=(sorted|unsorted)]
	 Only  show the given commits, but do not traverse their ancestors. This
	 has no effect if a range is specified.  If  the  argument  unsorted  is
	 given,  the  commits are shown in the order they were given on the com-
	 mand line. Otherwise (if sorted or no argument was given), the  commits
	 are shown in reverse chronological order by commit time. Cannot be com-
	 bined with --graph.

     --do-walk
	 Overrides a previous --no-walk.

   Commit Formatting
     Using  these options, git-rev-list(1) will act similar to the more special-
     ized  family  of  commit  log  tools:  git-log(1),  git-show(1),  and  git-
     whatchanged(1).

     --pretty[=<format>], --format=<format>
	 Pretty-print  the  contents of the commit logs in a given format, where
	 <format> can be one of oneline, short, medium, full, fuller, reference,
	 email, raw, format:<string> and tformat:<string>. When <format> is none
	 of  the  above,  and  has  %<placeholder>  in	it,  it   acts	 as   if
	 --pretty=tformat:<format> were given.

	 See  the  "PRETTY FORMATS" section for some additional details for each
	 format. When =<format> part is omitted, it defaults to medium.

	     Note
	     you can specify the default pretty format in the repository config-
	     uration (see git-config(1)).

     --abbrev-commit
	 Instead of showing the full 40-byte  hexadecimal  commit  object  name,
	 show a prefix that names the object uniquely.	--abbrev=<n> (which also
	 modifies diff output, if it is displayed) option can be used to specify
	 the minimum length of the prefix.

	 This  should make --pretty=oneline a whole lot more readable for people
	 using 80-column terminals.

     --no-abbrev-commit
	 Show the full 40-byte hexadecimal  commit  object  name.  This  negates
	 --abbrev-commit,  either  explicit  or implied by other options such as
	 --oneline. It also overrides the log.abbrevCommit variable.

     --oneline
	 This is a shorthand for --pretty=oneline --abbrev-commit used together.

     --encoding=<encoding>
	 Commit objects record the character encoding used for the  log  message
	 in  their  encoding header; this option can be used to tell the command
	 to re-code the commit log message in  the  encoding  preferred  by  the
	 user. For non plumbing commands this defaults to UTF-8. Note that if an
	 object  claims  to  be encoded in X and we are outputting in X, we will
	 output the object verbatim; this means that invalid  sequences  in  the
	 original  commit  may	be  copied  to the output. Likewise, if iconv(3)
	 fails to convert the commit, we will quietly output the original object
	 verbatim.

     --expand-tabs=<n>, --expand-tabs, --no-expand-tabs
	 Perform a tab expansion (replace each tab with enough spaces to fill to
	 the next display column that is a multiple of <n>) in the  log  message
	 before  showing  it  in  the output.  --expand-tabs is a short-hand for
	 --expand-tabs=8,  and	--no-expand-tabs  is  a  short-hand  for   --ex-
	 pand-tabs=0, which disables tab expansion.

	 By  default,  tabs  are  expanded in pretty formats that indent the log
	 message by 4 spaces (i.e.  medium, which  is  the  default,  full,  and
	 fuller).

     --show-signature
	 Check	the  validity of a signed commit object by passing the signature
	 to gpg --verify and show the output.

     --relative-date
	 Synonym for --date=relative.

     --date=<format>
	 Only takes effect for dates shown in  human-readable  format,	such  as
	 when using --pretty.  log.date config variable sets a default value for
	 the  log  command's  --date  option. By default, dates are shown in the
	 original time zone (either committer's or author's). If -local  is  ap-
	 pended  to  the format (e.g., iso-local), the user's local time zone is
	 used instead.

	 --date=relative shows dates relative to  the  current	time,  e.g.   "2
	 hours ago". The -local option has no effect for --date=relative.

	 --date=local is an alias for --date=default-local.

	 --date=iso (or --date=iso8601) shows timestamps in a ISO 8601-like for-
	 mat. The differences to the strict ISO 8601 format are:

	 *   a space instead of the T date/time delimiter

	 *   a space between time and time zone

	 *   no colon between hours and minutes of the time zone

	 --date=iso-strict (or --date=iso8601-strict) shows timestamps in strict
	 ISO 8601 format.

	 --date=rfc (or --date=rfc2822) shows timestamps in RFC 2822 format, of-
	 ten found in email messages.

	 --date=short  shows only the date, but not the time, in YYYY-MM-DD for-
	 mat.

	 --date=raw shows the  date  as  seconds  since  the  epoch  (1970-01-01
	 00:00:00  UTC), followed by a space, and then the timezone as an offset
	 from UTC (a + or - with four digits; the first two are hours,	and  the
	 second  two are minutes). I.e., as if the timestamp were formatted with
	 strftime("%s %z")). Note that the -local option  does	not  affect  the
	 seconds-since-epoch  value  (which is always measured in UTC), but does
	 switch the accompanying timezone value.

	 --date=human shows the timezone if the timezone does not match the cur-
	 rent time-zone, and doesn't print the whole date if  that  matches  (ie
	 skip  printing  year  for dates that are "this year", but also skip the
	 whole date itself if it's in the last few days and we can just say what
	 weekday it was). For older dates the hour and minute is also omitted.

	 --date=unix shows the date as a Unix  epoch  timestamp  (seconds  since
	 1970). As with --raw, this is always in UTC and therefore -local has no
	 effect.

	 --date=format:<format>  feeds the <format> to your system strftime, ex-
	 cept for %s, %z, and %Z, which are handled internally. Use  --date=for-
	 mat:%c  to  show the date in your system locale's preferred format. See
	 the strftime(3) manual for a complete list of format placeholders. When
	 using -local, the correct syntax is --date=format-local:<format>.

	 --date=default is the default format, and is based on ctime(3)  output.
	 It  shows a single line with three-letter day of the week, three-letter
	 month, day-of-month, hour-minute-seconds in "HH:MM:SS" format, followed
	 by 4-digit year, plus timezone information, unless the local time  zone
	 is used, e.g.	Thu Jan 1 00:00:00 1970 +0000.

     --header
	 Print	the  contents  of the commit in raw-format; each record is sepa-
	 rated with a NUL character.

     --no-commit-header
	 Suppress the header line containing "commit" and the object ID  printed
	 before  the  specified  format. This has no effect on the built-in for-
	 mats; only custom formats are affected.

     --commit-header
	 Overrides a previous --no-commit-header.

     --parents
	 Print also the parents of the commit (in the form "commit  parent...").
	 Also enables parent rewriting, see History Simplification above.

     --children
	 Print	also the children of the commit (in the form "commit child...").
	 Also enables parent rewriting, see History Simplification above.

     --timestamp
	 Print the raw commit timestamp.

     --left-right
	 Mark which side of a symmetric difference a commit is	reachable  from.
	 Commits from the left side are prefixed with < and those from the right
	 with >. If combined with --boundary, those commits are prefixed with -.

	 For example, if you have this topology:

			  y---b---b  branch B
			 / \ /
			/   .
		       /   / \
		      o---x---a---a  branch A

	 you would get an output like this:

		     $ git rev-list --left-right --boundary --pretty=oneline A...B

		     >bbbbbbb... 3rd on b
		     >bbbbbbb... 2nd on b
		     <aaaaaaa... 3rd on a
		     <aaaaaaa... 2nd on a
		     -yyyyyyy... 1st on b
		     -xxxxxxx... 1st on a

     --graph
	 Draw a text-based graphical representation of the commit history on the
	 left  hand side of the output. This may cause extra lines to be printed
	 in between commits, in order for the graph history to	be  drawn  prop-
	 erly. Cannot be combined with --no-walk.

	 This enables parent rewriting, see History Simplification above.

	 This  implies	the --topo-order option by default, but the --date-order
	 option may also be specified.

     --show-linear-break[=<barrier>]
	 When --graph is not used, all history branches are flattened which  can
	 make it hard to see that the two consecutive commits do not belong to a
	 linear branch. This option puts a barrier in between them in that case.
	 If  <barrier> is specified, it is the string that will be shown instead
	 of the default one.

     --count
	 Print a number stating how many commits would	have  been  listed,  and
	 suppress  all	other  output. When used together with --left-right, in-
	 stead print the counts for left and right commits, separated by a  tab.
	 When  used  together  with --cherry-mark, omit patch equivalent commits
	 from these counts and print the count for equivalent commits  separated
	 by a tab.

PRETTY FORMATS
     If the commit is a merge, and if the pretty-format is not oneline, email or
     raw,  an additional line is inserted before the Author: line. This line be-
     gins with "Merge: " and the hashes of ancestral commits are printed,  sepa-
     rated  by	spaces.  Note that the listed commits may not necessarily be the
     list of the direct parent commits if you have limited your view of history:
     for example, if you are only interested in changes related to a certain di-
     rectory or file.

     There are several built-in formats, and you can define  additional  formats
     by  setting a pretty.<name> config option to either another format name, or
     a format: string, as described below (see git-config(1)). Here are the  de-
     tails of the built-in formats:

     *	 oneline

	     <hash> <title-line>

	 This is designed to be as compact as possible.

     *	 short

	     commit <hash>
	     Author: <author>

	     <title-line>

     *	 medium

	     commit <hash>
	     Author: <author>
	     Date:   <author-date>

	     <title-line>

	     <full-commit-message>

     *	 full

	     commit <hash>
	     Author: <author>
	     Commit: <committer>

	     <title-line>

	     <full-commit-message>

     *	 fuller

	     commit <hash>
	     Author:	 <author>
	     AuthorDate: <author-date>
	     Commit:	 <committer>
	     CommitDate: <committer-date>

	     <title-line>

	     <full-commit-message>

     *	 reference

	     <abbrev-hash> (<title-line>, <short-author-date>)

	 This  format is used to refer to another commit in a commit message and
	 is the same as --pretty='format:%C(auto)%h (%s, %ad)'. By default,  the
	 date is formatted with --date=short unless another --date option is ex-
	 plicitly  specified.  As with any format: with format placeholders, its
	 output is not affected by other options like --decorate and  --walk-re-
	 flogs.

     *	 email

	     From <hash> <date>
	     From: <author>
	     Date: <author-date>
	     Subject: [PATCH] <title-line>

	     <full-commit-message>

     *	 mboxrd

	 Like email, but lines in the commit message starting with "From " (pre-
	 ceded	by zero or more ">") are quoted with ">" so they aren't confused
	 as starting a new commit.

     *	 raw

	 The raw format shows the entire commit exactly as stored in the  commit
	 object.  Notably,  the  hashes  are  displayed  in  full, regardless of
	 whether --abbrev or --no-abbrev are used, and parents information  show
	 the  true  parent commits, without taking grafts or history simplifica-
	 tion into account. Note that this format affects the  way  commits  are
	 displayed,  but  not the way the diff is shown e.g. with git log --raw.
	 To get full object names in a raw diff format, use --no-abbrev.

     *	 format:<format-string>

	 The format:<format-string> format allows you to specify which	informa-
	 tion  you  want to show. It works a little bit like printf format, with
	 the notable exception that you get a newline with %n instead of \n.

	 E.g, format:"The author of %h was %an,  %ar%nThe  title  was  >>%s<<%n"
	 would show something like this:

	     The author of fe6e0ee was Junio C Hamano, 23 hours ago
	     The title was >>t4119: test autocomputing -p<n> for traditional diff input.<<

	 The placeholders are:

	 *   Placeholders that expand to a single literal character:

	     %n
		 newline

	     %%
		 a raw %

	     %x00
		 %x  followed  by two hexadecimal digits is replaced with a byte
		 with the hexadecimal digits' value (we will call this	"literal
		 formatting code" in the rest of this document).

	 *   Placeholders that affect formatting of later placeholders:

	     %Cred
		 switch color to red

	     %Cgreen
		 switch color to green

	     %Cblue
		 switch color to blue

	     %Creset
		 reset color

	     %C(<spec>)
		 color specification, as described under Values in the "CONFIGU-
		 RATION  FILE"	section of git-config(1). By default, colors are
		 shown	only  when  enabled  for  log  output  (by   color.diff,
		 color.ui,  or	--color, and respecting the auto settings of the
		 former if we are going to a terminal).  %C(auto,<spec>) is  ac-
		 cepted   as   a  historical  synonym  for  the  default  (e.g.,
		 %C(auto,red)). Specifying %C(always,<spec>) will show the  col-
		 ors  even  when color is not otherwise enabled (though consider
		 just using --color=always to enable color for the whole output,
		 including this format and anything else git might color).  auto
		 alone (i.e.  %C(auto)) will turn on auto coloring on  the  next
		 placeholders until the color is switched again.

	     %m
		 left (<), right (>) or boundary (-) mark

	     %w([<w>[,<i1>[,<i2>]]])
		 switch line wrapping, like the -w option of git-shortlog(1).

	     %<(<n>[,(trunc|ltrunc|mtrunc)])
		 make  the  next  placeholder  take  at  least	N column widths,
		 padding spaces on the right if necessary.  Optionally	truncate
		 (with	ellipsis  ..)  at  the	left  (ltrunc)	..ft, the middle
		 (mtrunc) mi..le, or the end (trunc) rig..,  if  the  output  is
		 longer  than  <n>  columns.  Note 1: that truncating only works
		 correctly with <n> >= 2. Note 2: spaces around the <n> and  <m>
		 (see  below) values are optional. Note 3: Emojis and other wide
		 characters will take two display columns,  which  may	over-run
		 column boundaries. Note 4: decomposed character combining marks
		 may be misplaced at padding boundaries.

	     %<|(<m> )
		 make  the  next  placeholder take at least until <m> th display
		 column, padding spaces on the right if necessary. Use	negative
		 <m>  values  for  column positions measured from the right hand
		 edge of the terminal window.

	     %>(<n>), %>|(<m>)
		 similar to %<(<n>), %<|(<m>) respectively, but  padding  spaces
		 on the left

	     %>>(<n>), %>>|(<m>)
		 similar  to  %>(<n>), %>|(<m>) respectively, except that if the
		 next placeholder takes more spaces than  given  and  there  are
		 spaces on its left, use those spaces

	     %><(<n>), %><|(<m>)
		 similar  to  %<(<n>),	%<|(<m>)  respectively, but padding both
		 sides (i.e. the text is centered)

	 *   Placeholders that expand to information extracted from the commit:

	     %H
		 commit hash

	     %h
		 abbreviated commit hash

	     %T
		 tree hash

	     %t
		 abbreviated tree hash

	     %P
		 parent hashes

	     %p
		 abbreviated parent hashes

	     %an
		 author name

	     %aN
		 author name (respecting .mailmap, see git-shortlog(1)	or  git-
		 blame(1))

	     %ae
		 author email

	     %aE
		 author  email (respecting .mailmap, see git-shortlog(1) or git-
		 blame(1))

	     %al
		 author email local-part (the part before the @ sign)

	     %aL
		 author local-part (see %al) respecting .mailmap, see git-short-
		 log(1) or git-blame(1))

	     %ad
		 author date (format respects --date= option)

	     %aD
		 author date, RFC2822 style

	     %ar
		 author date, relative

	     %at
		 author date, UNIX timestamp

	     %ai
		 author date, ISO 8601-like format

	     %aI
		 author date, strict ISO 8601 format

	     %as
		 author date, short format (YYYY-MM-DD)

	     %ah
		 author date, human style (like the --date=human option of  git-
		 rev-list(1))

	     %cn
		 committer name

	     %cN
		 committer  name  (respecting  .mailmap,  see git-shortlog(1) or
		 git-blame(1))

	     %ce
		 committer email

	     %cE
		 committer email (respecting .mailmap,	see  git-shortlog(1)  or
		 git-blame(1))

	     %cl
		 committer email local-part (the part before the @ sign)

	     %cL
		 committer  local-part	(see  %cl) respecting .mailmap, see git-
		 shortlog(1) or git-blame(1))

	     %cd
		 committer date (format respects --date= option)

	     %cD
		 committer date, RFC2822 style

	     %cr
		 committer date, relative

	     %ct
		 committer date, UNIX timestamp

	     %ci
		 committer date, ISO 8601-like format

	     %cI
		 committer date, strict ISO 8601 format

	     %cs
		 committer date, short format (YYYY-MM-DD)

	     %ch
		 committer date, human style (like the	--date=human  option  of
		 git-rev-list(1))

	     %d
		 ref names, like the --decorate option of git-log(1)

	     %D
		 ref names without the " (", ")" wrapping.

	     %(decorate[:<option>,...])
		 ref  names  with custom decorations. The decorate string may be
		 followed by a colon and zero or more  comma-separated	options.
		 Option  values may contain literal formatting codes. These must
		 be used for commas (%x2C) and closing parentheses  (%x29),  due
		 to their role in the option syntax.

		 *   prefix=<value>:  Shown  before  the  list of ref names. De-
		     faults to " (".

		 *   suffix=<value>: Shown after the list of ref names. Defaults
		     to ")".

		 *   separator=<value>: Shown between  ref  names.  Defaults  to
		     ", ".

		 *   pointer=<value>:  Shown  between  HEAD  and  the  branch it
		     points to, if any. Defaults to " -> ".

		 *   tag=<value>: Shown before tag names. Defaults to "tag: ".

	 For example, to produce decorations with no  wrapping	or  tag  annota-
	 tions, and spaces as separators:

	 %(decorate:prefix=,suffix=,tag=,separator= )

	 %(describe[:<option>,...])
	     human-readable  name,  like git-describe(1); empty string for unde-
	     scribable commits. The describe string may be followed by	a  colon
	     and  zero	or more comma-separated options. Descriptions can be in-
	     consistent when tags are added or removed at the same time.

	     *	 tags[=<bool-value>]:  Instead	of  only  considering  annotated
		 tags, consider lightweight tags as well.

	     *	 abbrev=<number>:  Instead  of using the default number of hexa-
		 decimal digits (which will vary according to the number of  ob-
		 jects in the repository with a default of 7) of the abbreviated
		 object  name,	use <number> digits, or as many digits as needed
		 to form a unique object name.

	     *	 match=<pattern>: Only consider tags matching the given  glob(7)
		 <pattern>, excluding the refs/tags/ prefix.

	     *	 exclude=<pattern>:  Do  not  consider	tags  matching the given
		 glob(7) <pattern>, excluding the refs/tags/ prefix.

	 %S
	     ref name given on the command line by which the commit was  reached
	     (like git log --source), only works with git log

	 %e
	     encoding

	 %s
	     subject

	 %f
	     sanitized subject line, suitable for a filename

	 %b
	     body

	 %B
	     raw body (unwrapped subject and body)

	 %GG
	     raw verification message from GPG for a signed commit

	 %G?
	     show "G" for a good (valid) signature, "B" for a bad signature, "U"
	     for  a  good signature with unknown validity, "X" for a good signa-
	     ture that has expired, "Y" for a good signature made by an  expired
	     key,  "R"	for  a	good signature made by a revoked key, "E" if the
	     signature cannot be checked (e.g. missing key) and "N" for no  sig-
	     nature

	 %GS
	     show the name of the signer for a signed commit

	 %GK
	     show the key used to sign a signed commit

	 %GF
	     show the fingerprint of the key used to sign a signed commit

	 %GP
	     show  the	fingerprint  of the primary key whose subkey was used to
	     sign a signed commit

	 %GT
	     show the trust level for the key used to sign a signed commit

	 %gD
	     reflog selector,  e.g.,  refs/stash@{1}  or  refs/stash@{2  minutes
	     ago}; the format follows the rules described for the -g option. The
	     portion  before  the  @ is the refname as given on the command line
	     (so  git  log  -g	refs/heads/master  would  yield  refs/heads/mas-
	     ter@{0}).

	 %gd
	     shortened	reflog selector; same as %gD, but the refname portion is
	     shortened for human readability (so refs/heads/master becomes  just
	     master).

	 %gn
	     reflog identity name

	 %gN
	     reflog  identity  name (respecting .mailmap, see git-shortlog(1) or
	     git-blame(1))

	 %ge
	     reflog identity email

	 %gE
	     reflog identity email (respecting .mailmap, see git-shortlog(1)  or
	     git-blame(1))

	 %gs
	     reflog subject

	 %(trailers[:<option>,...])
	     display  the  trailers of the body as interpreted by git-interpret-
	     trailers(1). The trailers string may be followed  by  a  colon  and
	     zero  or  more  comma-separated  options. If any option is provided
	     multiple times, the last occurrence wins.

	     *	 key=<key>: only show trailers with specified <key>. Matching is
		 done case-insensitively and trailing colon is optional. If  op-
		 tion  is given multiple times trailer lines matching any of the
		 keys are shown. This option automatically enables the only  op-
		 tion so that non-trailer lines in the trailer block are hidden.
		 If  that  is  not  desired  it can be disabled with only=false.
		 E.g., %(trailers:key=Reviewed-by) shows trailer lines with  key
		 Reviewed-by.

	     *	 only[=<bool>]:   select  whether  non-trailer	lines  from  the
		 trailer block should be included.

	     *	 separator=<sep>: specify the separator inserted between trailer
		 lines. Defaults to a line feed character. The string <sep>  may
		 contain  the  literal	formatting codes described above. To use
		 comma as separator one must use %x2C as it would  otherwise  be
		 parsed  as  next  option.  E.g.,  %(trailers:key=Ticket,separa-
		 tor=%x2C ) shows all trailer lines whose key is "Ticket"  sepa-
		 rated by a comma and a space.

	     *	 unfold[=<bool>]: make it behave as if interpret-trailer's --un-
		 fold  option  was given. E.g., %(trailers:only,unfold=true) un-
		 folds and shows all trailer lines.

	     *	 keyonly[=<bool>]: only show the key part of the trailer.

	     *	 valueonly[=<bool>]: only show the value part of the trailer.

	     *	 key_value_separator=<sep>: specify the separator  inserted  be-
		 tween the key and value of each trailer. Defaults to ": ". Oth-
		 erwise it shares the same semantics as separator=<sep> above.

	 Note

	 Some  placeholders  may  depend  on other options given to the revision
	 traversal engine. For example, the %g* reflog options	will  insert  an
	 empty	string unless we are traversing reflog entries (e.g., by git log
	 -g). The %d and %D placeholders will use the "short" decoration  format
	 if --decorate was not already provided on the command line.

     The  boolean  options  accept an optional value [=<bool-value>]. The values
     taken by --type=bool git-config(1), like yes and  off,  are  all  accepted.
     Giving  a	boolean  option without =<value> is equivalent to giving it with
     =true.

     If you add a + (plus sign) after % of a placeholder,  a  line-feed  is  in-
     serted  immediately before the expansion if and only if the placeholder ex-
     pands to a non-empty string.

     If you add a - (minus sign) after	%  of  a  placeholder,	all  consecutive
     line-feeds  immediately  preceding the expansion are deleted if and only if
     the placeholder expands to an empty string.

     If you add a ' ' (space) after % of a placeholder, a space is inserted  im-
     mediately	before the expansion if and only if the placeholder expands to a
     non-empty string.

     *	 tformat:

	 The tformat: format works exactly like format:, except that it provides
	 "terminator" semantics  instead  of  "separator"  semantics.  In  other
	 words, each commit has the message terminator character (usually a new-
	 line)	appended,  rather  than a separator placed between entries. This
	 means that the final entry of a single-line  format  will  be	properly
	 terminated  with a new line, just as the "oneline" format does. For ex-
	 ample:

	     $ git log -2 --pretty=format:%h 4da45bef \
	       | perl -pe '$_ .= " -- NO NEWLINE\n" unless /\n/'
	     4da45be
	     7134973 -- NO NEWLINE

	     $ git log -2 --pretty=tformat:%h 4da45bef \
	       | perl -pe '$_ .= " -- NO NEWLINE\n" unless /\n/'
	     4da45be
	     7134973

	 In addition, any unrecognized string that has a % in it is  interpreted
	 as if it has tformat: in front of it. For example, these two are equiv-
	 alent:

	     $ git log -2 --pretty=tformat:%h 4da45bef
	     $ git log -2 --pretty=%h 4da45bef

EXAMPLES
     *	 Print the list of commits reachable from the current branch.

	     git rev-list HEAD

     *	 Print	the  list  of commits on this branch, but not present in the up-
	 stream branch.

	     git rev-list @{upstream}..HEAD

     *	 Format commits with their author  and	commit	message  (see  also  the
	 porcelain git-log(1)).

	     git rev-list --format=medium HEAD

     *	 Format  commits  along  with  their  diffs (see also the porcelain git-
	 log(1), which can do this in a single process).

	     git rev-list HEAD |
	     git diff-tree --stdin --format=medium -p

     *	 Print the list of commits on the current branch that touched  any  file
	 in the Documentation directory.

	     git rev-list HEAD -- Documentation/

     *	 Print	the  list  of  commits	authored by you in the past year, on any
	 branch, tag, or other ref.

	     git rev-list --author=you@example.com --since=1.year.ago --all

     *	 Print the list of objects reachable from the current branch (i.e.,  all
	 commits and the blobs and trees they contain).

	     git rev-list --objects HEAD

     *	 Compare  the disk size of all reachable objects, versus those reachable
	 from reflogs, versus the total packed size. This can tell  you  whether
	 running  git  repack  -ad might reduce the repository size (by dropping
	 unreachable objects), and whether expiring reflogs might help.

	     # reachable objects
	     git rev-list --disk-usage --objects --all
	     # plus reflogs
	     git rev-list --disk-usage --objects --all --reflog
	     # total disk size used
	     du -c .git/objects/pack/*.pack .git/objects/??/*
	     # alternative to du: add up "size" and "size-pack" fields
	     git count-objects -v

     *	 Report the disk size of each branch, not including objects used by  the
	 current  branch.  This  can  find  outliers  that are contributing to a
	 bloated repository size (e.g., because somebody accidentally  committed
	 large build artifacts).

	     git for-each-ref --format='%(refname)' |
	     while read branch
	     do
		     size=$(git rev-list --disk-usage --objects HEAD..$branch)
		     echo "$size $branch"
	     done |
	     sort -n

     *	 Compare  the  on-disk	size of branches in one group of refs, excluding
	 another. If you co-mingle objects from multiple  remotes  in  a  single
	 repository, this can show which remotes are contributing to the reposi-
	 tory size (taking the size of origin as a baseline).

	     git rev-list --disk-usage --objects --remotes=$suspect --not --remotes=origin
