Entering_Commands

   You can choose to enter commands interactively from DCL, or enter
   the utility and issue commands from the xauth command line.

   Note that SYS$LOGIN:DECW$XAUTHORITY.DECW$XAUTH is the default X
   authority file. If you want to work with an alternate file, use
   the -f option on the command line to specify the filename, as
   follows:

   $ XAUTH -f SYS$SYSROOT:[SYSMGR]UNTRUSTED.DECW$XAUTH
   Using authority file SYS$SYSROOT:[SYSMGR]UNTRUSTED.DECW$XAUTH

   xauth>

   Tips and Shortcuts

   o  If you are working with an X authority file other than the
      default, and plan to enter a series of commands, use the XAUTH
      -f command to enter the utility; then issue the subsequent
      commands from the utility command line. Otherwise, you will
      need to reenter the fully-qualified filename with each xauth
      command issued from the DCL command line.

   o  When adding a file entry, you can specify a period (.) in
      place of the value MIT-MAGIC-COOKIE-1. The period is replaced
      by the name of the authentication protocol.
