grepdiff − show files modified by a diff containing a regex
|
grepdiff [−n] [−−number−files] [−p n] [−−strip=n] [−−addprefix=PREFIX] [−s] [−i PATTERN] [−x PATTERN] [−v] [−E] [−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 |
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 |
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 only files matching PATTERN.
−x PATTERN
Exclude files matching PATTERN.
|
−E |
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
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. |
