Patching Source Code w/ a Diff file

[JoeyJoeJo]

I am trying to patch LIRC with the diff found at szremote.sourceforge.net to be able to use my streamzap ir remote. How do I patch it? I know there is a patch command, but I don't know how to use it.

The man page for patch is a good start. Generally it works this way:

patch -p0 < patchfile.diff

From the man:


-pnum or --strip=num
Strip the smallest prefix containing num leading slashes from each
file name found in the patch file. A sequence of one or more adja-
cent slashes is counted as a single slash. This controls how file
names found in the patch file are treated, in case you keep your
files in a different directory than the person who sent out the
patch. For example, supposing the file name in the patch file was

/u/howard/src/blurfl/blurfl.c

setting -p0 gives the entire file name unmodified, -p1 gives

u/howard/src/blurfl/blurfl.c

without the leading slash, -p4 gives

blurfl/blurfl.c

and not specifying -p at all just gives you blurfl.c. Whatever you
end up with is looked for either in the current directory, or the
directory specified by the -d option.
