    Command:

    sulogin

    
    
    

    SYNOPSIS

           sulogin [ -e ] [ -p ] [ -t SECONDS ] [ TTY ]
    
    
    

    DESCRIPTION

           sulogin can be invoked by init(8) when the system goes into single user
           mode.  (This is done through an entry in inittab(5).)  Init also  tries
           to  execute  sulogin when the boot loader (e.g., grub(8)) passes it the
           -b option.
    
           The user is prompted
    
                Give root password for system maintenance
                (or type Control-D for normal startup):
    
           sulogin will be connected to the current terminal, or to  the  optional
           device  that  can be specified on the command line (typically /dev/con-
           sole).
    
           If the -t option is used then the program only waits the  given  number
           of seconds for user input.
    
           If  the  -p option is used then the single-user shell is invoked with a
           dash as the first character in argv[0].  This causes the shell  process
           to behave as a login shell.  The default is not to do this, so that the
           shell will not read /etc/profile or $HOME/.profile at startup.
    
           After the user exits the single-user shell, or presses control-D at the
           prompt, the system will (continue to) boot to the default runlevel.
    
    
    

    ENVIRONMENT VARIABLES

           sulogin looks for the environment variable SUSHELL or sushell to deter-
           mine what shell to start. If the environment variable is  not  set,  it
           will  try  to  execute  root's shell from /etc/passwd. If that fails it
           will fall back to /bin/sh.
    
           This is very valuable together with the -b option to init. To boot  the
           system  into  single  user  mode,  with  the  root  file system mounted
           read/write, using a special "fail safe" shell that is statically linked
           (this example is valid for the LILO bootprompt)
    
           boot: linux -b rw sushell=/sbin/sash
    
    
    

    FALLBACK METHODS

           sulogin  checks  the root password using the standard method (getpwnam)
           first.  Then, if the -e option was specified,  sulogin  examines  these
           files directly to find the root password:
    
           /etc/passwd,
           /etc/shadow (if present)
    
           If  they  are  damaged  or nonexistent, sulogin will start a root shell
           without asking for a password. Only use the -e option if you  are  sure
