Obviously "man patch" is where you should start, but like many Unix man pages, the man page for "patch" is surprisingly obtuse for such an elegant and useful program. (BTW we are slightly off-topic for Python, but I am sympathetic to your basic problem.) The "patch" program is pretty smart about doing the correct thing once you grok its options, but if you are concerned about doing the wrong thing, I recommend you simply play around with it with some toy examples. Hopefully the example below demonstrates the basic premise behind "patch," which I think you already understand. The bells and whistles are mostly about "patch" being able to recognize that a diff applies to a specific file. Again, I would take a few minutes to experiment with a couple small files and diffs that you generate yourself before applying other people's patches. I haven't used "patch" a ton myself, so I'm no expert, but it's definitely a cool program, so it's worth learning. $ echo foo > foo $ cp foo foobetter $ echo better >> foobetter $ cat foo foo $ cat foobetter foo better $ diff foo foobetter 1a2 > better $ diff foo foobetter > make_foo_better $ patch foo make_foo_better patching file foo $ cat foo foo better -- http://mail.python.org/mailman/listinfo/python-list
