Use the XAUTH LIST command to display the contents of an X
    authority file.

    For example, the following XAUTH command displays the entries in
    the X authority file UNTRUSTED.DECW$XAUTH:

    $  XAUTH -f UNTRUSTED.DECW$XAUTH LIST
    local/ZEPHYR:0  MIT-MAGIC-COOKIE-1  cfcc5ef98f9718f90154f355c0ae9f62
    decnet/ZEPHYR::0  MIT-MAGIC-COOKIE-1  cfcc5ef98f9718f90154f355c0ae9f62
    116.94.24.187:0  MIT-MAGIC-COOKIE-1  cfcc5ef98f9718f90154f355c0ae9f62

                                   NOTE

       TCP/IP is considered the default transport for X authority
       file entries. As a result, the transport portion of the
       display name is assumed and not displayed for entries that
       use the TCP/IP transport.

    To limit the list to entries related to a particular display,
    enter the display name at the end of the XAUTH LIST command, as
    follows:

    $ XAUTH -f UNTRUSTED.DECW$XAUTH LIST ZEPHYR::0
    decnet/ZEPHYR::0  MIT-MAGIC-COOKIE-1  cfcc5ef98f9718f90154f355c0ae9f62

    With the TCPIP transport, multiple addresses may correspond to
    the same display name. When displaying X authority file entries,
    it may be difficult to distinguish which entry applies to which
    address. To differentiate the entries, use the -n qualifier to
    list them in numeric format, as follows:

    $ XAUTH LIST
    test13_2:0  MIT-MAGIC-COOKIE-1  12
    test13_2:0  MIT-MAGIC-COOKIE-1  23
    $ XAUTH -n LIST
    #0006#fe800000000000000200f8fffe101905#:0  MIT-MAGIC-COOKIE-1  12
    #0000#c0a70209#:0  MIT-MAGIC-COOKIE-1  23
