NAME
       lsdiff - show which files are modified by a patch

SYNOPSIS
       lsdiff [-n] [-p n] [--strip=n] [--addprefix=PREFIX] [-s] [-E]
	      [-i PATTERN] [-x PATTERN] [[-# RANGE] [--hunks=RANGE]]
	      [--lines=RANGE] [--files=RANGE] [[-H] [--with-filename]] [[-h]
	      [--no-filename]] [-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 (using -nv), 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 once, 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).

	      If the -v is given twice in conjunction with -n (i.e.  -nvv),
	      the format is slightly different: hunk-level descriptive text is
	      shown after each hunk number, and the --number-files option is
	      enabled.

       --number-files
	      File numbers are listed, beginning at 1, before each filename.

       -# RANGE | --hunks=RANGE
	      Only list hunks within the specified RANGE. Hunks are numbered
	      from 1, and the range is a comma-separated list of numbers or
	      “first-last” spans; either the first or the last in the span may
	      be omitted to indicate no limit in that direction.

       --lines=RANGE
	      Only list hunks that contain lines from the original file that
	      lie within the specified RANGE. Lines are numbered from 1, and
	      the range is a comma-separated list of numbers or “first-last”
	      spans; either the first or the last in the span may be omitted
	      to indicate no limit in that direction.

       --files=RANGE
	      Only list files indicated by the specified RANGE. Files are
	      numbered from 1 in the order they appear in the patch input, and
	      the range is a comma-separated list of numbers or “first-last”
	      spans; either the first or the last in the span may be omitted
	      to indicate no limit in that direction.

       -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 “!”.

       -E     Treat empty files as absent for the purpose of displaying file
	      additions, modifications and removals.

       -i PATTERN
	      Include only files matching PATTERN.

       -x PATTERN
	      Exclude files matching PATTERN.

       -H, --with-filename
	      Print the name of the patch file containing each patch.

       -h, --no-filename
	      Suppress the name of the patch file containing each patch.

       -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.

SEE ALSO
       filterdiff(1), grepdiff(1)

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)
