patchign c files

not sure in what form my question can be put as best Smilie

my question is i got three dir with many c files. 2 dirs are the source taken from a website where 1 is the old one and 2 is the new one. the 3 dir is the dir where i put my changed c code in. now i want to patch the diff file of dir 1 and 2 to dir 3.
i can be wrong in makeing the diff like diff 1 2 >cupdate and then i try todo patch 3 cupdate and that did go wrong.

i hope i am clear enough Smilie

This should work... although the patch process may require manual intervention if your changes in directory 3 are significant enough to disrupt the automated merging.

$ diff -ru 1/ 2/ > patchfile
$ cd 3/
$ patch -p1 < ../patchfile
