NAME

grepdiff - show files modified by a diff containing a regex  

SYNOPSIS

grepdiff [-n] [--number-files] [-p n] [--strip=n] [--addprefix=PREFIX] [-s] [-i PATTERN] [-x PATTERN] [-v] [-E] [[-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 lqpf_gfp_maskrq, 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
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
When matching, ignore the first n components of the pathname.
--strip=n
Remove the first n components of the pathname before displaying it.

-i PATTERN
Include only files matching PATTERN.
-x PATTERN
Exclude files matching PATTERN.
-E
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
Read regular expressions from FILE, one per line.
--output-matching=hunk|file
Display the matching hunk-level or file-level diffs.
