znol - notify via Zephyr upon login or logout of interesting people
] [ -f file
] [ -l
] [ -q
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:
- Turns notification on or off.
- 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
- 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.
- Disables printing who is currently logged in when subscribing. This option
may not be used in conjunction with the -l option.
- 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.
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'.
