rediff - Man Page

fix offsets and counts of a hand-edited diff



rediff EDITED

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

editdiff FILE

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


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 offsets or counts (the lines that begin ā€œ@@ā€). 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:

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.
