       rungetty - a minimal console getty that can run any process


       rungetty  [--noclear]  [--long-hostname]  [-u username] [-g group] [-w path] [-n priority]
       [--prompt [=string]] [-d n] [--autologin username] tty [--] [command] [arguments]


       rungetty is a getty for use on virtual consoles which has the ability to run any  program,
       not  just login(1).  Like mingetty(8), on which rungetty is based, rungetty isn't suitable
       for serial use. Both I and the author of mingetty(8) recommend mgetty(8) for that.  It  is
       useful,  though,  for keeping programs such as, say, telnet(1), running at all times. When
       running a program other than login, it is executed as the user and group  nobody,  or  the
       user specified by username and group specified by group.


              Do not clear the screen before prompting for the login name (the screen is normally

              By default the hostname is only printed until the  first  dot.   With  this  option
              enabled, the full text from gethostname() is shown.

       -u username
              By default, rungetty runs programs as nobody. With this option, it runs as the user

       -g group
              By default, rungetty runs as the group nobody.  This  option  allows  you  to  tell
              rungetty to run programs as the group group.

       --prompt [=string]
              This  option  causes  rungetty to wait until user input (usually an 'Enter') before
              executing the program. If string is specified, it will be displayed.  Otherwise,  a
              default prompt will be shown.

       -n n   ´nice´ value of specified program.

       -w path
              Working directory of specified program.

       -d n   Specifying  -d  will  make  rungetty  wait  n  seconds before running the specified

       --autologin username
              Log the specified user onto the console (normally /dev/tty1)  when  the  system  is
              first booted without prompting for a username or password.

              When  the  autologin  option  is supplied, rungetty will check that the controlling
              terminal is the console (normally /dev/tty1), that a reasonable username  has  been
              supplied, and that this is the first autologin request since the system has booted.
              If all of these conditions have been met, a request for an unauthenticated login is
              passed to the login program.  Otherwise, a normal interactive login is performed.

              The  login  program  may  deny the request for an unauthenticated login.  Typically
              this will happen when the user is root, has a  UID  of  0,  or  whenever  a  normal
              interactive  login  would be denied due to the access restrictions specified in the
              nologin, usertty, or securetty files.

              Only a single autologin request will  be  issued  after  a  system  boot.   If  the
              automated login request is denied, or if the user logs out, rungetty will revert to
              performing normal interactive logins for all subsequent login requests.

       --     Tells rungetty that there  are  no  more  options  to  parse,  useful  for  passing
              arguments with a - in them to the external program.


       tty    Name of the tty to run on.

              Runs  specified  command.   Searches  for  command  in  /bin,  /usr/bin,  /usr/ucb,
              /usr/local/bin if the complete pathname and filename are not given.

              Command line arguments to pass to command.


       rungetty recognizes the following  escapes  sequences  which  might  be  embedded  in  the
       /etc/issue file:

       \d     insert current day (localtime),

       \l     insert line on which rungetty is running,

       \m     inserts machine architecture (uname -m),

       \n     inserts machine's network node hostname (uname -n),

       \o     inserts domain name,

       \r     inserts operating system release (uname -r),

       \t     insert current time (localtime),

       \s     inserts operating system name,

       \u resp. \U
              the  current  number of users which are currently logged in.  \U inserts "n users",
              where as \u only inserts "n".

       \v     inserts operating system version (uname -v).


       In /etc/inittab, these lines:
       r1:12345:respawn:/sbin/rungetty tty1
       r2:2345:respawn:/sbin/rungetty tty2 telnet
       r3:2345:respawn:/sbin/rungetty tty3 -u support top
       r4:2345:respawn:/sbin/rungetty tty4 -n 20 -w /etc rc5des
       Would run a local login on /dev/tty1,a telnet(1) session to on  /dev/tty2,and
       top(5)on  /dev/tty3.   Note  that  telnet(1) is run as user nobody, while top(5) is run as
       user support, and start the program rc5des(5) at the lowest priority level with a  current
       directory of /etc.


       /etc/issue, /var/run/utmp, /var/log/autologin.
