+== NAME
+
+sulogin - single-user login
+
+== SYNOPSIS
+
+*sulogin* [options] [_tty_]
+
+== DESCRIPTION
+
+*sulogin* is invoked by *init* when the system goes into single-user mode.
+
+The user is prompted:
+
+Give root password for system maintenance (or type Control-D for normal startup):
+
+If the root account is locked and *--force* is specified, no password is required.
+
+*sulogin* will be connected to the current terminal, or to the optional _tty_ device that can be specified on the command line (typically _/dev/console_).
+
+When the user exits from the single-user shell, or presses control-D at the prompt, the system will continue to boot.
+
+== OPTIONS
+
+*-e*, *--force*::
+If 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 '{asterisk}' at the begin of the password then *sulogin* will *start a root shell without asking for a password*.
+//TRANSLATORS: Keep {asterisk} untranslated.
++
+Only use the *-e* option if you are sure the console is physically protected against unauthorized access.
+
+*-p*, *--login-shell*::
+Specifying this option causes *sulogin* to start the shell process as a login shell.
+
+*-t*, *--timeout* _seconds_::
+Specify the maximum amount of time to wait for user input. By default, *sulogin* will wait forever.
+
+include::man-common/help-version.adoc[]
+
+== 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.
