SYNOPSIS
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] [[-FRANGE] |
[--files=RANGE]] [[-H] | [--with-filename]] [[-h] |
[--no-filename]] [[-v] | [--verbose]...] [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
-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(1) instead.
--grep
Behave like grepdiff(1) instead.
SEE ALSO
filterdiff(1), grepdiff(1)
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)
