DESCRIPTION
     For each file modified by a patch, if the patch  hunk  contains  the  REGEX
     then the file's name is printed.

     The regular expression is treated as POSIX Basic Regular Expression syntax,
     unless  the -E option is given in which case POSIX Extended Regular Expres-
     sion syntax is used. When compiled with PCRE2 support, PCRE regular expres-
     sions are used instead of POSIX regular expressions, and the -E option  has
     no  effect since PCRE already supports extended regular expression features
     by default.

     For example, to see the patches in my.patch which contain the  regular  ex-
     pression "pf_gfp_mask", use:

	 grepdiff pf_gfp_mask my.patch | \
	   xargs -rn1 filterdiff my.patch -i

     You can use both unified and context format diffs with this program.

OPTIONS
     -n, --line-number
	 Display the line number that each patch begins at. If verbose output is
	 requested, each matching hunk is listed as well.

	 For a description of the output format see lsdiff(1).

     -N, --number-files
	 File numbers are listed, beginning at 1, before each filename.

     -p n, --strip-match=n
	 When matching, ignore the first n components of the pathname.

     --strip=n
	 Remove the first n components of the pathname before displaying it.

     --addprefix=PREFIX
	 Prefix  the  pathname with PREFIX before displaying it. This will over-
	 ride any individual  settings	specified  with  the  --addoldprefix  or
	 --addnewprefix options.

     --addoldprefix=PREFIX
	 Prefix pathnames for old or original files in the output by PREFIX.

     --addnewprefix=PREFIX
	 Prefix pathnames for updated or new files in the output by PREFIX.

     -s
	 Show file additions, modifications and removals. A file addition is in-
	 dicated by a "+", a removal by a "-", and a modification by a "!".

     -i PATTERN, --include=PATTERN
	 Include only files matching PATTERN.

     -I FILE, --include-from-file=FILE
	 Include only files matching any pattern listed in FILE, one pattern per
	 line. All other lines in the input are suppressed.

     -x PATTERN --exclude=PATTERN
	 Exclude files matching PATTERN.

     -X FILE, --exclude-from-file=FILE
	 Exclude  files  matching  any	pattern  listed in FILE, one pattern per
	 line. All other lines in the input are displayed.

     -# RANGE, --hunks=RANGE
	 Only include hunks within the specified RANGE. Hunks are numbered  from
	 1,  and  the range is a comma-separated list of numbers or "first-last"
	 spans, optionally preceded by a modifier 'x' which inverts  the  entire
	 range; either the first or the last in the span may be omitted to indi-
	 cate no limit in that direction.

     --lines=RANGE
	 Only  list  hunks  that  contain  lines from the original file that lie
	 within the specified RANGE. Lines are numbered from 1, and the range is
	 a comma-separated list of numbers  or	"first-last"  spans,  optionally
	 preceded  by  a modifier 'x' which inverts the entire range; either the
	 first or the last in the span may be omitted to indicate  no  limit  in
	 that direction.

     -F=RANGE, --files=RANGE
	 Only  list  files  indicated by the specified RANGE. Files are numbered
	 from 1 in the order they appear in the patch input, and the range is  a
	 comma-separated  list of numbers or "first-last" spans, optionally pre-
	 ceded by a modifier 'x' which inverts	the  entire  range;  either  the
	 first	or  the  last in the span may be omitted to indicate no limit in
	 that direction.

     --annotate
	 Annotate each hunk with the filename and hunk number.

     --as-numbered-lines=before|after|original-before|original-after
	 Instead of a patch fragment, display the lines of  the  selected  hunks
	 with  the  line  number  of the file before (or after) the patch is ap-
	 plied, followed by a TAB character and a colon,  at  the  beginning  of
	 each  line.  Each  hunk except the first will have a line consisting of
	 "..."	before it.

	 The before and after options show line numbers adjusted for any skipped
	 hunks. The original-before and original-after options show line numbers
	 as they appear in the original diff, preserving the original line  num-
	 ber  context.	This is useful for CI/CD systems that need to report er-
	 rors on the exact line numbers from the original diff.

     --format=unified|context
	 Use specified output format.

     --remove-timestamps
	 Do not include file timestamps in the output.

     -z, --decompress
	 Decompress files with extensions .gz and .bz2.

     -E, --extended-regexp
	 Use POSIX Extended Regular Expression syntax. Note: when compiled  with
	 PCRE2	support,  this	option has no effect as PCRE regular expressions
	 are used by default and already  support  extended  regular  expression
	 features.

     -H, --with-filename
	 Print the name of the patch file containing each match.

     -h, --no-filename
	 Suppress the name of the patch file containing each match.

     -f FILE, --file=FILE
	 Read regular expressions from FILE, one per line.

     --output-matching=hunk|file
	 Display the matching hunk-level or file-level diffs.

     --only-match=rem|removals|add|additions|mod|modifications|all
	 Limit regex matching to removals, additions, modifications or the whole
	 hunk.

     --help
	 Display a short usage message.

     --version
	 Display the version number of grepdiff.

     --filter
	 Behave like filterdiff(1) instead.

     --list
	 Behave like lsdiff(1) instead.
