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
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, 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.
