grepdiff

GREPDIFF(1)															       GREPDIFF(1)

NAME

       grepdiff - show files modified by a diff containing a regex

SYNOPSIS

       grepdiff [-n] [-p n] [--strip=n] [--addprefix=PREFIX] [-s] [-i PATTERN] [-x PATTERN] {REGEX} [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.

       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     Display the line number that each patch begins at.

       -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.

       --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 only files matching PATTERN.

       -x PATTERN
	      Exclude files matching PATTERN.

       --help Display a short usage message.

       --version
	      Display the version number of grepdiff.

       --filter
