run command without sudo password
# Run `visudo` to edit the file `/etc/sudoers`: sudo visudo # For example, to allow the `shutdown` command to run without a password. # Add this to the file, replacing `myusername` with your own login name for your PC: myusername ALL = NOPASSWD: /sbin/shutdown # NOTE: `sudo` is still required to run the command so you still have to specify the command as: sudo shutdown
