.SH NAME
|
||||
zlocate \- find a user using Zephyr
|
||||
.SH SYNOPSIS
|
||||
.B zlocate
|
||||
[
|
||||
.B -a
|
||||
|
|
||||
.B -d
|
||||
] [
|
||||
.B -1
|
||||
] [
|
||||
.B -p
|
||||
] user ...
|
||||
.SH DESCRIPTION
|
||||
.I Zlocate
|
||||
uses the
|
||||
.I Zephyr(1)
|
||||
Notification Service to find where a user is currently logged in. If
|
||||
the user is not logged in, or has set his location information such that
|
||||
you do not have access to see it,
|
||||
.I zlocate
|
||||
prints "Hidden or not logged-in". Otherwise, each machine that the
|
||||
user is currently logged into is printed, along with the time of
|
||||
login and location. The location is usually the X window system display
|
||||
name of the user's display, but may be the terminal name if he is not
|
||||
using X or for some other reason is only using the terminal interface to
|
||||
.I zwgc(1).
|
||||
|
||||
By default, all zlocate requests are authenticated using
|
||||
.IR Kerberos .
|
||||
If you do not have Kerberos tickets, or for some other reason do not
|
||||
want to authenticate, the
|
||||
.B -d
|
||||
option will turn off authentication. The
|
||||
.B -a
|
||||
option is the default, authentication on.
|
||||
|
||||
When locating multiple users,
|
||||
.I zlocate
|
||||
will display the user name on a line by itself, followed by the locations for that user. To display the user name on the same line as the output, use the
|
||||
.B -1
|
||||
option (the numeral one).
|
||||
|
||||
To look up multiple users in parallel asynchronously, use the
|
||||
.B -p
|
||||
option.
|
||||
|
||||
.SH DIAGNOSTICS
|
||||
.I zlocate
|
||||
exits with status zero (0) if at least one user was found, and one (1)
|
||||
if no users were found.
