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-numberDisplay 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-filesFile numbers are listed, beginning at 1, before each filename.
-# RANGE,
--hunks=RANGEOnly 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=RANGEOnly 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=RANGEOnly 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=nWhen matching, ignore the first
n components of the
pathname.
--strip=nRemove the first n
components of the pathname before displaying
it.
--addprefix=PREFIXPrefix the pathname with
PREFIX before displaying
it.
-s, --statusShow 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-removedTreat empty files as absent for the purpose of displaying file additions, modifications and removals.
-i PATTERN,
--include=PATTERNInclude only files matching
PATTERN.
-x PATTERN,
--exclude=PATTERNExclude files matching
PATTERN.
-z,
--decompressDecompress files with extensions .gz and .bz2.
-H, --with-filenamePrint the name of the patch file containing each patch.
-h, --no-filenameSuppress the name of the patch file containing each patch.
-v, --verboseVerbose output.
--helpDisplay a short usage message.
--versionDisplay the version number of lsdiff.
--filterBehave like filterdiff(1) instead.
--grepBehave like grepdiff(1) instead.
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)
