Have you ever encountered an error message that says “permission denied” while trying to use a command line tool? Or maybe the command you’re trying to use requires root access? Instead of retyping the entire command followed by sudo, you can use a simple trick to re-execute the last command with sudo privileges using “sudo !!”. This works on both MacOS / Mac OS X and Linux.
Executing the Last Command with Root Access
To quickly execute the last command as root, simply type:
sudo !!
This will prepend “sudo” to the last executed command, allowing you to run it with root privileges. You will be prompted to enter your administrator password to complete the session.
This trick works with virtually every command line tool and command, saving you time and effort.
