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
