What is difference between diff and patch ?..

Answer / Neha Arora

Diff is a tool that compares two files or directories to identify the differences between them. The output of diff can be saved as a patch file, which contains instructions on how to apply the changes found by diff to a third file to bring it up-to-date with one of the original files. A patch file typically has the extension .patch.
