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

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

DESCRIPTION
       Znol  provides  a  way  for  you to be notified when "interesting" people log in or out.  It uses the Zephyr(1) Notification 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 considered 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 subscrip-
       tions for notices about those users.
	    znol -l -u foo
       prints the location (if visible) of the user 'foo'.

FILES
       $HOME/.anyone
