grepdiff {[−−help] | [−−version] | [−−list] | [−−filter ...]} |
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.
−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).
−N, −−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, 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.
−−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.
−−only−match=rem|removals|add|additions|mod|modifications|all
Limit regex matching to removals, additions, modifications or the whole hunk.
−−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.
