Screen User's Manual

8.4.10 Su

Command: su [username [password [password2]]]

(none)
Substitute the user of a display. The command prompts for all parameters that are omitted. If passwords are specified as parameters, they have to be specified un-crypted. The first password is matched against the systems passwd database, the second password is matched against the screen password as set with the commands acladd or password. Su may be useful for the screen administrator to test multiuser setups. When the identification fails, the user has access to the commands available for user `nobody'. These are detach, license, version, help and displays.
