I had asked how to apply patch in a debian package?. After that I had tried to figure out patches against interesting packages and was able to get a script that tells that. cleaning output of a script so it's descending, gives package names and cleanly exists. Now I came to know of something similar to patch called a debdiff which is part of devscripts. I saw the manpage (which I couldn't understand or make a head or tail of). I tried various search engine keyword manipulations to get if there is a way to use debdiff to do what we do with patch but came up empty. One of the patches which interests me is https://bugs.debian.org/845173. As can be seen it has a debdiff and not a patch. Conceptually though, both seem similar or/and same. They may or may not be subtle differences that I'm aware of.
My query is would the command be the same — e.g. is
$ patch -p1 < ../$whatever.debdiff
the same as
$ patch -p1 < ../$whatever.patch
or are there any differences or anything that I should know/remember to try out?
