.SH DESCRIPTION
|
|
.I Znol
|
|
provides a way for you to be notified when "interesting" people log in
|
|
or out. It uses the
|
|
.I 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
|
|
.I znol
|
|
is executed is printed to stdout. The control arguments are as
|
|
follows:
|
|
.TP 12
|
|
.B on|off
|
|
Turns notification on or off.
|
|
.TP
|
|
.B \-f
|
|
The namelist file is taken to be
|
|
.I file.
|
|
If
|
|
.I file
|
|
is "-", then the standard input is used instead of a file. If
|
|
.I file
|
|
does not exist, an error message is printed, and
|
|
.I znol
|
|
exits.
|
|
This option may not be used in conjunction with the
|
|
.B \-u
|
|
option.
|
|
.TP
|
|
.B \-l
|
|
Causes
|
|
.I 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
|
|
.BI \-q
|
|
option.
|
|
.TP
|
|
.B \-q
|
|
Disables printing who is currently logged in when subscribing. This
|
|
option may not be used in conjunction with the
|
|
.BI \-l
|
|
option.
|
|
.TP
|
|
.B \-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
|
|
.B \-f
|
|
option.
|
|
