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 `%'.
