xnlock

XNLOCK(1)						      General Commands Manual							 XNLOCK(1)

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.

RESOURCES

       xnlock.font:		  fontname
       xnlock.foreground:	  color
       xnlock.background:	  color
       xnlock.reverseVideo:	  True/False
       xnlock.text:		  Some random text string
       xnlock.program:		  program [args]
       xnlock.ignorePasswd:	  True/False
       xnlock.acceptRootPasswd:   True/False

FILES

       xnlock		    executable file
       ~/.msgfile		  default message file
