NAME

       xnlock - amusing lock screen program with message for passers-by

SYNOPSIS

       xnlock [ options ] [ message ]

DESCRIPTION

       xnlock  is  a  program  that acts as a screen saver for workstations running X11.  It also
       "locks" the screen such that the workstation can be left  unattended  without  worry  that
       someone  else will walk up to it and mess everything up.  When xnlock is running, a little
       man with a big nose and a hat runs around spewing out messages to the screen.  By default,
       the messages are "humorous", but that depends on your sense of humor.

       If  a  key or mouse button is pressed, a prompt is printed requesting the user's password.
       If a RETURN is not typed within 30 seconds, the little man resumes running around.

       Text on the command line is used as the message.  For example:
            % xnlock I´m out to lunch for a couple of hours.
       Note the need to quote shell metacharacters.

       In the absence of flags or text, xnlock displays random fortunes.

OPTIONS

       Command line options override all resource specifications.  All  arguments  that  are  not
       associated with a command line option is taken to be message text that the little man will
       "say" every once in a while.  The resource xnlock.text may be set to a string.

       -fn fontname
              The default font is the first 18 point font in the new century  schoolbook  family.
              While  larger  fonts  are  recokmmended over smaller ones, any font in the server's
              font list will work.  The resource to use for this option is xnlock.font.

       -filename  filename
              Take the message to be displayed from  the  file  filename.   If  filename  is  not
              specified,  $HOME/.msgfile is used.  If the contents of the file are changed during
              runtime, the most recent text of the file is used (allowing the  displayed  message
              to be altered remotely).  Carriage returns within the text are allowed, but tabs or
              other control characters are not translated and should not be used.   The  resource
              available for this option is xnlock.file.

       -ar    Accept  root's  password  to  unlock  screen.  This option is true by default.  The
              reason for this is so that someone's screen may be unlocked by autorized  users  in
              case  of  emergency  and the person running the program is still out to lunch.  The
              resource available for specifying this option is xnlock.acceptRootPasswd.

       -noar  Don't accept root's password.  This option is for paranoids who  fear  their  peers
              might breakin using root's password and remove their files anyway.  Specifying this
              option on the command line overrides the xnlock.acceptRootPasswd if set to True.

       -ip    Ignore  password   prompt.    The   resource   available   for   this   option   is
              xnlock.ignorePasswd.

       -noip  Don't  ignore password prompt.  This is available in order to override the resource
              ignorePasswd if set to True.

       -fg color
              Specifies  the  foreground   color.    The   resource   available   for   this   is
              xnlock.foreground.

       -bg color
              Specifies   the   background   color.    The   resource   available   for  this  is
              xnlock.background.

       -rv    Reverse  the  foreground  and  background  colors.   The  resource  for   this   is
              xvnlock.reverseVideo.

       -norv  Don't  use  reverse video.  This is available to override the reverseVideo resource
              if set to True.

       -prog program
              Receive message text from the running program program. If there  are  arguments  to
              program,  encase  them  with  the  name  of  the  program in quotes (e.g. xnlock -t
              "fortune -o").  The resource for this is xnlock.program.
