NAME

       zlocate - find a user using Zephyr

SYNOPSIS

       zlocate [ -a | -d ] [ -1 ] [ -p ] user ...

DESCRIPTION

       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.

DIAGNOSTICS

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