    SU(VIII)                     10/31/73                    SU(VIII)

    NAME
         su  -  become privileged user

    SYNOPSIS
         su

    DESCRIPTION
         Su allows one to become the super-user, who has all sorts of
         marvelous (and correspondingly dangerous) powers.  In  order
         for su to do its magic, the user must supply a password.  If
         the password is correct, su will execute the Shell with  the
         UID  set  to  that of the super-user.  To restore normal UID
         privileges, type an end-of-file to the super-user Shell.

         The password demanded is that of the entry ``root''  in  the
         system's password file.

         To  remind the super-user of his responsibilities, the Shell
         substitutes `#' for its usual prompt `%'.
