znol - notify via Zephyr upon login or logout of interesting people
znol [ on|off ] [ -f file ] [ -u username ] [ -l ] [ -q ]
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
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
-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
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'.
