NAME

grepdiff - show files modified by a diff containing a regex

SYNOPSIS

	grepdiff [[-n] \| [--line-number]] [[-N] \| [--number-files]] [[-p n ] \| [--strip-match= n ]] [--strip= n ] [--addprefix= PREFIX ] [--addoldprefix= PREFIX ] [--addnewprefix= PREFIX ] [[-s] \| [--status]] [[-i PATTERN ] \| [--include= PATTERN ]] [[-I FILE ] \| [--include-from-file= FILE ]] [[-x PATTERN ] \| [--exclude= PATTERN ]] [[-X FILE ] \| [--exclude-from-file= FILE ]] [[-# RANGE ] \| [--hunks= RANGE ]] [--lines= RANGE ] [[-F RANGE ] \| [--files= RANGE ]] [--annotate] [--as-numbered-lines= WHEN ] [--format= FORMAT ] [--remove-timestamps] [[-v] \| [--verbose]] [[-z] \| [--decompress]] [[-E] \| [--extended-regexp]] [[-H] \| [--with-filename]] [[-h] \| [--no-filename]] [--output-matching= WHAT ] [--only-match= WHAT ] {[ REGEX ] \| [-f FILE ]} [ file ...]
	grepdiff {[--help] \| [--version] \| [--list] \| [--filter ...]}

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).

-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.
