The diff files must be listed in the order that they are to be applied. For best results, the diffs must have at least three lines of context. Since combinediff 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 be in strict incremental order. In other words, the second patch must be relative to the state of the original set of files after the first patch was applied. The diffs may be in context format. The output, however, will be in unified format. OPTIONS -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).) If this option is not specified, combinediff will automatically determine the optimal number of path components to strip by finding the smallest value where at least one file matches between the two patches. -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 pat- tern. 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. Also makes patch application ig- nore whitespace when reconstructing files. -b, --ignore-space-change Ignore changes in the amount of whitespace. -B, --ignore-blank-lines Ignore changes whose lines are all blank. --color=WHEN colorize the output; WHEN can be 'never', 'always', or 'auto' (default: auto, use 'never' to disable) -z, --decompress Decompress files with extensions .gz and .bz2. --interpolate Run as "interdiff". See interdiff(1) for more information about how the behaviour is altered in this mode. --combine Run as "combinediff". This is the default. --help Display a short usage message. --version Display the version number of combinediff. BUGS The -U option is a bit erratic: it can control the amount of context dis- played for files that are modified in both patches, but not for files that only appear in one patch (which appear with the same amount of context in the output as in the input).
