A shell prompt... The man page says: SYNOPSIS su [-] [-flm] [-c class] [login [args]] ... -c class Use the settings of the specified login class. Only allowed for the super-user. ... EXAMPLES su man -c catman Runs the command catman as user man. You will be asked for man's password unless your real UID is 0. su man -c 'catman /usr/share/man /usr/local/man /usr/X11R6/man' Same as above, but the target command consists of more than a sin- gle word and hence is quoted for use with the -c option being passed to the shell. (Most shells expect the argument to -c to be a single word). su -c staff man -c 'catman /usr/share/man /usr/local/man /usr/X11R6/man' Same as above, but the target command is run with the resource limits of the login class ``staff''. Note: in this example, the first -c option applies to su while the second is an argument to the shell being invoked. It seems -c is used in the examples to specify a command AND a class. >How-To-Repeat: See above. >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
