DESCRIPTION¶
interdiff creates a unified format diff that expresses the difference between two diffs. The diffs must both be relative to the same files. For best results, the diffs must have at least three lines of context. To reverse a patch, use /dev/null for diff2. To reduce the amount of context in a patch, use:interdiff -U1 /dev/null patchfile
OPTIONS¶
-hIgnored, for compatibility with older versions of
interdiff. This option will go away soon.
-p n, --strip-match=n
When comparing filenames, ignore the first n
pathname components from both patches. (This is similar to the -p
option to GNU patch(1).)
-q, --quiet
Quieter output. Don't emit rationale lines at the
beginning of each patch.
-U n, --unified=n
Attempt to display n lines of context (requires at
least n lines of context in both input files). (This is similar to the
-U option to GNU diff(1).)
-d PATTERN, --drop-context=PATTERN
Don't display any context on files that match the shell
wildcard PATTERN. This option can be given multiple times.
Note that the interpretation of the shell wildcard pattern does not count slash
characters or periods as special (in other words, no flags are given to
fnmatch). This is so that “*/basename”-type patterns can
be given without limiting the number of pathname components.
-i, --ignore-case
Consider upper- and lower-case to be the same.
-w, --ignore-all-space
Ignore whitespace changes in patches.
-b, --ignore-space-change
Ignore changes in the amount of whitespace.
-B, --ignore-blank-lines
Ignore changes whose lines are all blank.
-z, --decompress
Decompress files with extensions .gz and .bz2.
--interpolate
Run as “interdiff”. This is the
default.
--combine
Run as “combinediff”. See
combinediff(1) for more information about how the behaviour is altered
in this mode.
--no-revert-omitted
(For interpolation mode only) When a file is changed by
the first patch but not by the second, don't revert that change.
--help
Display a short usage message.
--version
Display the version number of interdiff.
EXAMPLES¶
Basic usage:interdiff -z 3.2pre1.patch.gz 3.2pre2.patch.gz
interdiff patch /dev/null
filterdiff -i file.c patchfile | \ interdiff /dev/stdin /dev/null
BUGS¶
There are currently no known bugs in interdiff; but there are some caveats. If you find a bug, please report it (along with a minimal test case) to Tim Waugh <twaugh@redhat.com>. There are some sets of patches in which there is just not enough information to produce a proper interdiff. In this case, the strategy employed is to revert the original patch and apply the new patch. This, unfortunately, means that interdiffs are not guaranteed to be reversible.SEE ALSO¶
