What are the dark corners of Vim your mom never told you about? [closed]

by

Might not be one that 99% of Vim users don’t know about, but it’s something I use daily and that any Linux+Vim poweruser must know.

Basic command, yet extremely useful.

:w !sudo tee %

I often forget to sudo before editing a file I don’t have write permissions on. When I come to save that file and get a permission error, I just issue that vim command in order to save the file without the need to save it to a temp file and then copy it back again.

You obviously have to be on a system with sudo installed and have sudo rights.
