NAME
grepdiff - show files modified by a diff containing a regex
SYNOPSIS
grepdiff [[-n] | [--line-number]] [--number-files] [[-p n] |
[--strip-match=n]] [--strip=n] [--addprefix=PREFIX] [[-s] |
[--status]] [[-i PATTERN] | [--include=PATTERN]] [[-x PATTERN]
| [--exclude=PATTERN]] [[-v] | [--verbose]] [[-E] |
[--extended-regexp]] [[-H] | [--with-filename]] [[-h] |
[--no-filename]] [--output-matching=WHAT] {[REGEX] |
[-f FILE]} [file...]
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).
--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.
-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.
-x PATTERN --exclude=PATTERN
Exclude files matching PATTERN.
-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.
