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.
