Invokes the X Authority utility (xauth) that enables you to
    manage the contents of one or more X authority files. The X
    authority file contains information used to authorize client
    connections to the X display server.

    This utility is typically used to extract authorization records
    from one system and combine them with the records on another
    system, such as when granting access to additional users or
    enabling remote logins. The actual record entries vary depending
    on the authentication scheme currently in use.

    In contrast to other X Window System utilities that are available
    with DECwindows Motif, xauth is included as a part of OpenVMS
    Alpha and OpenVMS I64 operating systems. The xauth commands are
    case-insensitive and available directly from the DCL command
    line, xauth command line, or from a batch file.

    Format:

    XAUTH [-f authfile] [-options...] [command]
