ZNOL(1)
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 subscrib
- ing. 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'.
