NAME

lsdiff - show which files are modified by a patch

SYNOPSIS

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 , --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, optionally preceded 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, optionally preceded 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, optionally preceded 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 (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 'ˆ+' | \
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)
