NAME

lsdiff - show which files are modified by a patch

SYNOPSIS

TagDescription
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

TagDescription
-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 \(lqHunk #\(rq, 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 \(lqfirst-last\(rq 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 \(lqfirst-last\(rq 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 \(lqfirst-last\(rq 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 \(lq+\(rq, a removal by a \(lq-\(rq, and a modification by a \(lq!\(rq.
-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.

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)
