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.
