SU(1)SU(1)NAMEsu - substitute user id temporarily
SYNOPSISsu [ userid ]
DESCRIPTION
Su demands the password of the specified userid, and if it is given,
changes to that userid and invokes the Shell sh(1) without changing the
current directory or the user environment (see environ(5)). The new
user ID stays in force until the Shell exits.
If no userid is specified, `root' is assumed. To remind the super-user
of his responsibilities, the Shell substitutes `#' for its usual
prompt.
