grepdiff {[--help] | [--version] | [--list] | [--filter ...]}

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.
