You looked at 'man diff', right?
Yes.
and linux/Documentation/SubmittingPatches, which says:
Use "diff -up" or "diff -uprN" to create patches.
well, the "or" doesn't tells me the that there is a best way. That's the
deal.
So you use the options that are appropriate for your patches.
If you are patching only one file (or a few files in the same
directory), -up is usually fine.
Excelent.
If you have patches in multiple directories and you want diff
to search in subdirectories for patches, you need to use -r
(recursive).
If you are adding new files, you need to use -N.
Adding new files into the whole source? Like it will make a patch with
the full content and then create the file when patching the source?
Thanks for that one, sounds like I will need to use it.
Is there a specific problem that you are trying to solve?
I was just patching a README :-) and the patch looked too big and/or
bulky, so I noticed it was using a lot of lines from the document, but I
was only changing a single letter in a word. i.e. I changed/added 20
letters in total, and the patch is like 200 words.
I think it's just me being a paranoid patch-newbie.
Thanks,
.Alejandro
