How to take diff of two directories and apply the created patch to original one?

Question

I am newbie to using diff. I wish to create a patch to content of a directory recursively and give it to some one so that he could patch to a directory(slightly different) with him. Thanks in advance. Would be glad if some can clarify me as to how can I make it possible.

Answer 1

Just create a patch using something like

diff -cr originaldirectory/ updateddirectory/ > your.patch

And apply using

patch -p0 -i your.patch
