NAME
       znol - notify via Zephyr upon login or logout of interest
       ing people

SYNOPSIS
       znol [ on|off ] [ -f file ] [ -u username ] [ -l ] [ -q ]

DESCRIPTION
       Znol provides a way for you to be notified when "interest
       ing"  people log in or out.  It uses the Zephyr(1) Notifi
       cation Service, which causes a message to appear	 on  your
       screen  for  every  person  specified in a namelist (which
       defaults to $HOME/.anyone).  The namelist should have  one
       login  name  per line.  Any line starting with `#' is con
       sidered a comment and ignored.  Anyone in the namelist who
       is  logged  in when znol is executed is printed to stdout.
       The control arguments are as follows:

       on|off	   Turns notification on or off.

       -f	   The namelist file is taken  to  be  file.   If
		   file	 is  "-", then the standard input is used
		   instead of a file. If file does not exist,  an
		   error  message  is  printed,	 and  znol exits.
		   This option may not	be  used  in  conjunction
		   with the -u option.

       -l	   Causes  znol	 to  just  list the people in the
		   namelist who are currently logged in,  without
		   subscribing	to  the	 login	messages.    This
		   option may not be used in conjunction with the
		   -q option.

       -q	   Disables  printing  who is currently logged in
		   when subscribing.  This option may not be used
		   in conjunction with the -l option.

       -u	   Instead  of	reading	 a  file  to  specify the
		   "interesting" users, the next argument is used
		   as  the  only "interesting" user.  This option
		   may not be used in  conjunction  with  the  -f
		   option.

EXAMPLES
	    znol
       reads  the standard namelist file, prints the locations of
       any users named therein which can be found on the  system,
       and enters subscriptions for notices about those users.
	    znol -l -u foo
       prints the location (if visible) of the user 'foo'.

FILES
       $HOME/.anyone
