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.
