execute a command as another user

-l[l] [command]
            If no command is specified, the -l (list) option will list the allowed (and forbidden)
            commands for the invoking user (or the user specified by the -U option) on the current host.
            If a command is specified and is permitted by the security policy, the fully-qualified path
            to the command is displayed along with any command line arguments.  If command is specified
            but not allowed, sudo will exit with a status value of 1.  If the -l option is specified with
            an l argument (i.e. -ll), or if -l is specified multiple times, a longer list format is used.
