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 Expression syntax is used.

       For example, to see the patches in my.patch which contain the regular
       expression "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
	   override 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
	   indicated 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, optionially preceeded 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.

       --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,
	   optionially preceeded 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, optionially preceeded	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
	   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 applied, 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.

       --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.

       -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.

       --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.
