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
	      Behave like filterdiff(1) instead.

       --list Behave like lsdiff(1) instead.

NAME

       lsdiff - show which files are modified by a patch

SYNOPSIS

       lsdiff [-n] [-p n] [--strip=n] [--addprefix=PREFIX] [-s]
	      [-i PATTERN] [-x PATTERN] [-v] [file...]

       lsdiff {--help | --version | --filter ... | --grep ...}

DESCRIPTION

       List the files modified by a patch.

       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 hunk of each patch is listed as well.

	      For  each  file  that  is  modified, a line is generated containing the line number of the beginning of the patch, followed by a Tab
	      character, followed by the name of the file that is modified. If -v is given, following each of these lines will	be  one  line  for
	      each hunk, consisting of a Tab character, the line number that the hunk begins at, another Tab character, the string ``Hunk #'', and
	      the hunk number (starting at 1).

       -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.

       -v     Verbose output.

       --help Display a short usage message.

       --version
	      Display the version number of lsdiff.

       --filter
	      Behave like filterdiff(1) instead.

       --grep Behave like grepdiff(1) instead.

EXAMPLES

       To sort the order of touched files in a patch, you can use:

	      lsdiff patch | sort -u | 
		xargs -rn1 filterdiff patch -i

       To show only added files in a patch:

	      lsdiff -s patch | grep '^+' | 
		cut -c2- | xargs -rn1 filterdiff patch -i

       To show the headers of all file hunks:

	      lsdiff -n patch | (while read n file
		do sed -ne "$n,$(($n+1))p" patch
	      done)
