zlocate - find a user using Zephyr

Zlocate uses the 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, 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 zwgc(1).

       By  default, all zlocate requests are authenticated using Kerberos.  If you do not have Kerberos tickets,
       or for some other reason do not want to authenticate, the -d option will turn off authentication.  The -a
       option is the default, authentication on.

       When locating multiple users, 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 -1 option (the
       numeral one).

       To look up multiple users in parallel asynchronously, use the -p option.

zlocate exits with status zero (0) if at least one user was found, and one (1) if no users were found.
