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.
