DESCRIPTION¶
For each file modified by a patch, if the patch hunk contains the REGEX then the file's name is printed. The regular expression is treated as POSIX Basic Regular Expression syntax, unless the -E option is given in which case POSIX Extended Regular Expression syntax is used. For example, to see the patches in my.patch which contain the regular expression “pf_gfp_mask”, use:grepdiff pf_gfp_mask my.patch | \ xargs -rn1 filterdiff my.patch -i
OPTIONS¶
-n, --line-numberDisplay the line number that each patch begins at. If
verbose output is requested, each matching hunk is listed as well.
For a description of the output format see lsdiff(1).
--number-files
File numbers are listed, beginning at 1, before each
filename.
-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. This will override any individual settings specified with the
--addoldprefix or --addnewprefix options.
--addoldprefix=PREFIX
Prefix pathnames for old or original files in the output
by PREFIX.
--addnewprefix=PREFIX
Prefix pathnames for updated or new files in the output
by PREFIX.
-s
Show file additions, modifications and removals. A file
addition is indicated by a “+”, a removal by a
“-”, and a modification by a “!”.
-i PATTERN, --include=PATTERN
Include only files matching PATTERN.
-I FILE, --include-from-file=FILE
Include only files matching any pattern listed in
FILE, one pattern per line. All other lines in the input are
suppressed.
-x PATTERN --exclude=PATTERN
Exclude files matching PATTERN.
-X FILE, --exclude-from-file=FILE
Exclude files matching any pattern listed in FILE,
one pattern per line. All other lines in the input are displayed.
-# RANGE, --hunks=RANGE
Only include 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.
--annotate
Annotate each hunk with the filename and hunk
number.
--as-numbered-lines=before|after
Instead of a patch fragment, display the lines of the
selected hunks with the line number of the file before (or after) the patch is
applied, followed by a TAB character and a colon, at the beginning of each
line. Each hunk except the first will have a line consisting of
“...” before it.
--format=unified|context
Use specified output format.
--remove-timestamps
Do not include file timestamps in the output.
-z, --decompress
Decompress files with extensions .gz and .bz2.
-E, --extended-regexp
Use POSIX Extended Regular Expression syntax.
-H, --with-filename
Print the name of the patch file containing each
match.
-h, --no-filename
Suppress the name of the patch file containing each
match.
-f FILE, --file=FILE
Read regular expressions from FILE, one per
line.
--output-matching=hunk|file
Display the matching hunk-level or file-level
diffs.
--help
Display a short usage message.
--version
Display the version number of grepdiff.
--filter
Behave like filterdiff(1) instead.
--list
Behave like lsdiff(1) instead.
