You canuse interdiff to create an incremental patchbetween two patches that are against a commonsource tree, combinediff for creating acumulative diff from two incremental patches, andflipdiff to transpose two incremental patches.Filterdiff is for extracting or excluding patchesfrom a patch set based on modified files matchingshell wildcards. Lsdiff lists modified files in apatch. Rediff, recountdiff, and unwrapdiff correcthand-edited (or otherwise broken) patches.License: GNU General Public License (GPL)Changes:

REDIFF(1)																 REDIFF(1)

NAME

       rediff, editdiff - fix offsets and counts of a hand-edited diff

SYNOPSIS

       rediff ORIGINAL EDITED

       rediff EDITED

       rediff {--help | --version}

       editdiff FILE

       editdiff {--help | --version}

DESCRIPTION

       You  can  use rediff to correct a hand-edited unified diff. Take a copy of the diff you want to edit, and edit it without changing any off-
       sets or counts (the lines that begin ``@@''). Then run rediff, telling it the name of the original diff file and the name of  the  one  you
       have edited, and it will output the edited diff file but with corrected offsets and counts.

       A small script, editdiff, is provided for editing a diff file in-place.

       The types of changes that are currently handled are:

       o  Modifying the text of any file content line (of course).

       o  Adding new line insertions or deletions.

       o  Adding, changing or removing context lines. Lines at the context horizon are dealt with by adjusting the offset and/or count.

       o  Adding a single hunk (@@-prefixed section).

       o  Removing multiple hunk (@@-prefixed sections).

       Alternatively,  if only one argument is provided, it is taken to be the edited file and the counts and offsets are adjusted as appropriate.
       Some assumptions are made when used in this mode. See recountdiff(1) for more information.

OPTIONS

       --help Display a short usage message.
