sudo

Executes a single command as the superuser or another user. More information: https://www.sudo.ws/sudo.html.

• Run a command as the superuser:

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

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

sudo {{[-e|--edit]}} {{/etc/fstab}}

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

sudo {{[-u|--user]}} {{user}} {{[-g|--group]}} {{group}} {{id -a}}

• Repeat the last command prefixed with sudo (only in Bash, Zsh, etc.):

sudo !!

• Launch the default shell with superuser privileges and run login-specific files (.profile, .bash_profile, etc.):

sudo {{[-i|--login]}}

• Launch the default shell with superuser privileges without changing the environment:

sudo {{[-s|--shell]}}

• Launch the default shell as the specified user, loading the user's environment and reading login-specific files (.profile, .bash_profile, etc.):

sudo {{[-i|--login]}} {{[-u|--user]}} {{user}}

• List the allowed (and forbidden) commands for the invoking user:

sudo {{[-ll|--list --list]}}
