How to run the previous command with sudo quickly

Last updated 7 weeks ago

Here's another pro tip. Say you wanted to run a command in sudo context but forgot that. Usually you'd hit the up arrow, press ctrl+a, or HOME button, type sudo and hit ENTER.

There is a geekier way to do that. Just type:

$ sudo !!

Bash will expand the two exclamation points to the previous command and it will be run through sudo.
