Hope this isn't a FAQ, I looked and couldn't find it.
I don't know how to apply some of the patch files that are found with some software distributions (UNIX). For example, I was playing around with the tin software distribution and it contains a patch file which was created using diff -rcs. It contains difference entries for all of the changed files in that one file. I think I'm supposed to use this file as a script to ed and run it somehow to actually make the changes using a command such as
ed file < patch_file
It works for making single file changes (from the diff file) but not for multiple files. I'm sure something else needs to be done, but can't figure it out. I'm sure this is pretty basic and any help would be appreciated. Thanks...
