Question

I got two files. I want to use diff to compare those to see what has been changed. I checked man diff but there are log of options. Could anyone give me a quick hint what should I do? thank you you all!!

$ diff -u module.erl.orig module.erl.new

will give you a differences between files in unified form. You can also save them to a file

$ diff -u module.erl.orig module.erl.new > module.erl.patch

And patch an original file to have these changes:

$ patch -p module.erl.orig < module.erl.patch
