NAME
sulogin - single-user loginSYNOPSIS
sulogin [options] [tty]DESCRIPTION
sulogin is invoked by init when the system goes into single-user mode.OPTIONS
-e, --forceIf the default method of obtaining the root
password from the system via getpwnam(3) fails, then examine
/etc/passwd and /etc/shadow to get the password. If these files
are damaged or nonexistent, or when root account is locked by '!' or '*' at
the begin of the password then sulogin will start a root shell
without asking for a password.
Only use the -e option if you are sure the console is physically
protected against unauthorized access.
Specifying this option causes sulogin
to start the shell process as a login shell.
Specify the maximum amount of time to wait for
user input. By default, sulogin will wait forever.
Display help text and exit.
Print version and exit.
ENVIRONMENT
sulogin looks for the environment variable SUSHELL or sushell to determine 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.AUTHORS
sulogin was written by Miquel van Smoorenburg for sysvinit and later ported to util-linux by Dave Reisner and Karel Zak.REPORTING BUGS
