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 subscriptions for notices about those users.
            znol -l -u foo
       prints the location (if visible) of the user 'foo'.

FILES

       $HOME/.anyone
