interdiff {[--help] | [--version]}

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

Since interdiff doesn't have the advantage of being able to look at the files that are to
be modified, it has stricter requirements on the input format than patch(1) does. The
output of GNU diff will be okay, even with extensions, but if you intend to use a
hand-edited patch it might be wise to clean up the offsets and counts using recountdiff(1)
first.

Note, however, that the two patches must both be relative to the versions of the same
original set of files.

The diffs may be in context format. The output, however, will be in unified format.

OPTIONS


-h
Ignored, 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

Reversing a patch:

interdiff patch /dev/null

Reversing part of a patch (and ignoring the rest):

filterdiff -i file.c patchfile | \
interdiff /dev/stdin /dev/null
