SU(8)                       System Manager's Manual                      SU(8)



NAME
       su - substitute user id temporarily

SYNOPSIS
       /etc/su [ user ]

DESCRIPTION
       Su  demands  the  password for the login name user, and if it is given,
       changes to that userid and invokes the Shell sh(1) without changing the
       current  directory.   The user environment is unchanged except for HOME
       and SHELL, which are taken from the password file for  the  user  being
       substituted  (see environ(5)).  The new userid stays in force until the
       Shell exits.

       If no user is specified, `root' is assumed.  To remind  the  super-user
       of  his  responsibilities,  the  Shell  substitutes  `#'  for its usual
       prompt.
