# sudo

> Executes a single command as the superuser or another user.

- Run a command as the superuser:

`sudo {{less /var/log/syslog}}`

- Edit a file as the superuser with your default editor:

`sudo -e {{/etc/fstab}}`

- Run a command as another user and/or group:

`sudo -u {{user}} -g {{group}} {{id -a}}`

- Repeat the last command prefixed with "sudo" (only in bash, zsh, etc.):

`sudo !!`

- Launch the default shell with superuser privileges:

`sudo -i`
