DESCRIPTION

List the files modified by a patch.

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

OPTIONS

-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.

-N, –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, optionially preceeded by a modifier ‘x’ which
inverts the entire range; 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,
optionially preceeded by a modifier ‘x’ which inverts the entire
range; either the first or the last in the span may be omitted to
indicate no limit in that direction.

-F=RANGE, –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, optionially preceeded by a modifier ‘x’ which inverts the
entire range; 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 instead.

–grep
Behave like grepdiff instead.

filterdiff, grepdiff

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)
