grepdiff − show files modified by a diff containing a regex
|
grepdiff [[−n] | [−−line−number]] [−−number−files] [[−p n] | [−−strip−match=n]] [−−strip=n] [−−addprefix=PREFIX] [[−s] | [−−status]] [[−i PATTERN] | [−−include=PATTERN]] [[−x PATTERN] | [−−exclude=PATTERN]] [[−v] | [−−verbose]] [[−E] | [−−extended−regexp]] [[−H] | [−−with−filename]] [[−h] | [−−no−filename]] [−−output−matching=WHAT] {[REGEX] | [−f FILE]} [file...] | |
|
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).
−−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.
−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.
−x PATTERN −−exclude=PATTERN
Exclude files matching PATTERN.
−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.
