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