lsdiff − show which files are modified by a patch

lsdiff [[−n] | [−−line−number]] [[−p n] | [−−strip−match=n]] [−−strip=n] [−−addprefix=PREFIX] [[−s] | [−−status]] [[−E] | [−−empty−files−as−removed]] [[−i PATTERN] | [−−include=PATTERN]] [[−x PATTERN] | [−−exclude=PATTERN]] [[−z] | [−−decompress]] [[−# RANGE] | [−−hunks=RANGE]] [−−lines=RANGE] [−−files=RANGE] [[−H] | [−−with−filename]] [[−h] | [−−no−filename]] [[−v] | [−−verbose]...] [file...]

lsdiff {[−−help] | [−−version] | [−−filter ...] | [−−grep ...]}

List the files modified by a patch.

You can use both unified and context format diffs with this program.

−n, −−line−number

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, −−strip−match=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, −−status

Show file additions, modifications and removals. A file addition is indicated by a “+”, a removal by a “−”, and a modification by a “!”.

−E, −−empty−files−as−removed

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

−i PATTERN, −−include=PATTERN

Include only files matching PATTERN.

−x PATTERN, −−exclude=PATTERN

Exclude files matching PATTERN.

−z, −−decompress

Decompress files with extensions .gz and .bz2.

−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

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.

filterdiff(1), grepdiff(1)

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)
