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'.
