Diff file with vim

A small trick to diff 2 files with vim

Demo

• First open file_a.txt in vim.

• Then open another file, file_b.txt in split mode (:vsp file_b.txt).

• Incase we need to diff file_a.txt with file_b.txt then press <Ctrl-W> + w (press control button + w then w).

• We are in file_a.txt, run :diffthis.

• Go to file_b.txt press <Ctrl-W> + w and run :diffthis.

• Wala..magic right!, it’s show diff between 2 files.

• After that we can disable diff by run :diffoff both of file…done.
