None.

===== Syntax =====

  * ''**su** [//username// [//password// [//password2//]]]''

===== Description =====

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
system's passwd database and 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]]''.
