       git-for-each-ref	- Output information on	each ref

       git for-each-ref	[--count=<count>] [--shell|--perl|--python|--tcl]
			  [(--sort=<key>)...] [--format=<format>] [<pattern>...]
			  (--merged[=<object>] | --no-merged[=<object>])
			  [--contains[=<object>]] [--no-contains[=<object>]]

       Iterate over all	refs that match	<pattern> and show them	according to
       the given <format>, after sorting them according	to the given set of
       <key>. If <count> is given, stop	after showing that many	refs. The
       interpolated values in <format> can optionally be quoted	as string
       literals	in the specified host language allowing	their direct
       evaluation in that language.

	   If one or more patterns are given, only refs	are shown that match
	   against at least one	pattern, either	using fnmatch(3) or literally,
	   in the latter case matching completely or from the beginning	up to
	   a slash.

	   By default the command shows	all refs that match <pattern>. This
	   option makes	it stop	after showing that many	refs.

	   A field name	to sort	on. Prefix - to	sort in	descending order of
	   the value. When unspecified,	refname	is used. You may use the
	   --sort=<key>	option multiple	times, in which	case the last key
	   becomes the primary key.

	   A string that interpolates %(fieldname) from	a ref being shown and
	   the object it points	at. If fieldname is prefixed with an asterisk
	   (*) and the ref points at a tag object, use the value for the field
	   in the object which the tag object refers to	(instead of the	field
	   in the tag object). When unspecified, <format> defaults to
	   %(objectname) SPC %(objecttype) TAB %(refname). It also
	   interpolates	%% to %, and %xx where xx are hex digits interpolates
	   to character	with hex code xx; for example %00 interpolates to \0
	   (NUL), %09 to \t (TAB) and %0a to \n	(LF).

	   Respect any colors specified	in the --format	option.	The <when>
	   field must be one of	always,	never, or auto (if <when> is absent,
	   behave as if	always was given).

       --shell,	--perl,	--python, --tcl
	   If given, strings that substitute %(fieldname) placeholders are
	   quoted as string literals suitable for the specified	host language.
	   This	is meant to produce a scriptlet	that can directly be `eval`ed.

	   Only	list refs which	points at the given object.

	   Only	list refs whose	tips are reachable from	the specified commit
	   (HEAD if not	specified), incompatible with --no-merged.

	   Only	list refs whose	tips are not reachable from the	specified
	   commit (HEAD	if not specified), incompatible	with --merged.

	   Only	list refs which	contain	the specified commit (HEAD if not

	   Only	list refs which	don't contain the specified commit (HEAD if
	   not specified).

	   Sorting and filtering refs are case insensitive.

       Various values from structured fields in	referenced objects can be used
       to interpolate into the resulting output, or as sort keys.

       For all objects,	the following names can	be used:

	   The name of the ref (the part after $GIT_DIR/). For a non-ambiguous
	   short name of the ref append	:short.	The option
	   core.warnAmbiguousRefs is used to select the	strict abbreviation
	   mode. If lstrip=<N> (rstrip=<N>) is appended, strips	<N>
	   slash-separated path	components from	the front (back) of the
	   refname (e.g.  %(refname:lstrip=2) turns refs/tags/foo into foo and
	   %(refname:rstrip=2) turns refs/tags/foo into	refs). If <N> is a
	   negative number, strip as many path components as necessary from
	   the specified end to	leave -<N> path	components (e.g.
	   %(refname:lstrip=-2)	turns refs/tags/foo into tags/foo and
	   %(refname:rstrip=-1)	turns refs/tags/foo into refs).	When the ref
	   does	not have enough	components, the	result becomes an empty	string
	   if stripping	with positive <N>, or it becomes the full refname if
	   stripping with negative <N>.	Neither	is an error.

	   strip can be	used as	a synonym to lstrip.

	   The type of the object (blob, tree, commit, tag).

	   The size of the object (the same as git cat-file -s reports).
	   Append :disk	to get the size, in bytes, that	the object takes up on
	   disk. See the note about on-disk sizes in the CAVEATS section

	   The object name (aka	SHA-1).	For a non-ambiguous abbreviation of
	   the object name append :short. For an abbreviation of the object
	   name	with desired length append :short=<length>, where the minimum
	   length is MINIMUM_ABBREV. The length	may be exceeded	to ensure
	   unique object names.

	   This	expands	to the object name of the delta	base for the given
	   object, if it is stored as a	delta. Otherwise it expands to the
	   null	object name (all zeroes).

	   The name of a local ref which can be	considered "upstream" from the
	   displayed ref. Respects :short, :lstrip and :rstrip in the same way
	   as refname above. Additionally respects :track to show "[ahead N,
	   behind M]" and :trackshort to show the terse	version: ">" (ahead),
	   "<" (behind), "<>" (ahead and behind), or "=" (in sync).  :track
	   also	prints "[gone]"	whenever unknown upstream ref is encountered.
	   Append :track,nobracket to show tracking information	without
	   brackets (i.e "ahead	N, behind M").

	   For any remote-tracking branch %(upstream), %(upstream:remotename)
	   and %(upstream:remoteref) refer to the name of the remote and the
	   name	of the tracked remote ref, respectively. In other words, the
	   remote-tracking branch can be updated explicitly and	individually
	   by using the	refspec	%(upstream:remoteref):%(upstream) to fetch
	   from	%(upstream:remotename).

	   Has no effect if the	ref does not have tracking information
	   associated with it. All the options apart from nobracket are
	   mutually exclusive, but if used together the	last option is

	   The name of a local ref which represents the	@{push}	location for
	   the displayed ref. Respects :short, :lstrip,	:rstrip, :track,
	   :trackshort,	:remotename, and :remoteref options as upstream	does.
	   Produces an empty string if no @{push} ref is configured.

	   * if	HEAD matches current ref (the checked out branch), ' '

	   Change output color.	Followed by :<colorname>, where	color names
	   are described under Values in the "CONFIGURATION FILE" section of
	   git-config(1). For example, %(color:bold red).

	   Left-, middle-, or right-align the content between %(align:...) and
	   %(end). The "align:"	is followed by width=<width> and
	   position=<position> in any order separated by a comma, where	the
	   <position> is either	left, right or middle, default being left and
	   <width> is the total	length of the content with alignment. For
	   brevity, the	"width=" and/or	"position=" prefixes may be omitted,
	   and bare <width> and	<position> used	instead. For instance,
	   %(align:<width>,<position>).	If the contents	length is more than
	   the width then no alignment is performed. If	used with --quote
	   everything in between %(align:...) and %(end) is quoted, but	if
	   nested then only the	topmost	level performs quoting.

	   Used	as %(if)...%(then)...%(end) or
	   %(if)...%(then)...%(else)...%(end). If there	is an atom with	value
	   or string literal after the %(if) then everything after the %(then)
	   is printed, else if the %(else) atom	is used, then everything after
	   %(else) is printed. We ignore space when evaluating the string
	   before %(then), this	is useful when we use the %(HEAD) atom which
	   prints either "*" or	" " and	we want	to apply the if	condition only
	   on the HEAD ref. Append ":equals=<string>" or ":notequals=<string>"
	   to compare the value	between	the %(if:...) and %(then) atoms	with
	   the given string.

	   The ref which the given symbolic ref	refers to. If not a symbolic
	   ref,	nothing	is printed. Respects the :short, :lstrip and :rstrip
	   options in the same way as refname above.

	   The absolute	path to	the worktree in	which the ref is checked out,
	   if it is checked out	in any linked worktree.	Empty string

       In addition to the above, for commit and	tag objects, the header	field
       names (tree, parent, object, type, and tag) can be used to specify the
       value in	the header field.

       For commit and tag objects, the special creatordate and creator fields
       will correspond to the appropriate date or name-email-date tuple	from
       the committer or	tagger fields depending	on the object type. These are
       intended	for working on a mix of	annotated and lightweight tags.

       Fields that have	name-email-date	tuple as its value (author, committer,
       and tagger) can be suffixed with	name, email, and date to extract the
       named component.

       The complete message in a commit	and tag	object is contents. Its	first
       line is contents:subject, where subject is the concatenation of all
       lines of	the commit message up to the first blank line. The next	line
       is contents:body, where body is all of the lines	after the first	blank
       line. The optional GPG signature	is contents:signature. The first N
       lines of	the message is obtained	using contents:lines=N.	Additionally,
       the trailers as interpreted by git-interpret-trailers(1)	are obtained
       as trailers (or by using	the historical alias contents:trailers).
       Non-trailer lines from the trailer block	can be omitted with
       trailers:only. Whitespace-continuations can be removed from trailers so
       that each trailer appears on a line by itself with its full content
       with trailers:unfold. Both can be used together as

       For sorting purposes, fields with numeric values	sort in	numeric	order
       (objectsize, authordate,	committerdate, creatordate, taggerdate). All
       other fields are	used to	sort in	their byte-value order.

       There is	also an	option to sort by versions, this can be	done by	using
       the fieldname version:refname or	its alias v:refname.

       In any case, a field name that refers to	a field	inapplicable to	the
       object referred by the ref does not cause an error. It returns an empty
       string instead.

       As a special case for the date-type fields, you may specify a format
       for the date by adding :	followed by date format	name (see the values
       the --date option to git-rev-list(1) takes).

       Some atoms like %(align)	and %(if) always require a matching %(end). We
       call them "opening atoms" and sometimes denote them as %($open).

       When a scripting	language specific quoting is in	effect,	everything
       between a top-level opening atom	and its	matching %(end)	is evaluated
       according to the	semantics of the opening atom and only its result from
       the top-level is	quoted.

       An example directly producing formatted text. Show the most recent 3
       tagged commits:


	   git for-each-ref --count=3 --sort='-*authordate' \
	   --format='From: %(*authorname) %(*authoremail)
	   Subject: %(*subject)
	   Date: %(*authordate)
	   Ref:	%(*refname)

	   ' 'refs/tags'

       A simple	example	showing	the use	of shell eval on the output,
       demonstrating the use of	--shell. List the prefixes of all heads:


	   git for-each-ref --shell --format="ref=%(refname)" refs/heads | \
	   while read entry
		   eval	"$entry"
		   echo	`dirname $ref`

       A bit more elaborate report on tags, demonstrating that the format may
       be an entire script:




		   if test "z$t" = z
			   # could be a	lightweight tag
			   kind="Lightweight tag"
		   echo	"$kind $T points at a $t object	$o"
		   if test "z$t" = zcommit
			   echo	"The commit was	authored by $n $e
	   at $d, and titled


	   Its message reads as:
			   echo	"$b" | sed -e "s/^/    /"

	   eval=`git for-each-ref --shell --format="$fmt" \
		   --sort='*objecttype'	\
		   --sort=-taggerdate \
	   eval	"$eval"

       An example to show the usage of %(if)...%(then)...%(else)...%(end).
       This prefixes the current branch	with a star.

	   git for-each-ref --format="%(if)%(HEAD)%(then)* %(else)  %(end)%(refname:short)" refs/heads/

       An example to show the usage of %(if)...%(then)...%(end). This prints
       the authorname, if present.

	   git for-each-ref --format="%(refname)%(if)%(authorname)%(then) Authored by: %(authorname)%(end)"

       Note that the sizes of objects on disk are reported accurately, but
       care should be taken in drawing conclusions about which refs or objects
       are responsible for disk	usage. The size	of a packed non-delta object
       may be much larger than the size	of objects which delta against it, but
       the choice of which object is the base and which	is the delta is
       arbitrary and is	subject	to change during a repack.

       Note also that multiple copies of an object may be present in the
       object database;	in this	case, it is undefined which copy's size	or
       delta base will be reported.
