DESCRIPTION

       The xrdfs utility executes meta-data oriented operations (e.g., ls, mv, rm, etc.) on one
       or more xrootd servers.  Command help is available by invoking xrdfs with no command line
       options or parameters and then typing "help" in response to the input prompt.

OPTIONS

       --no-cwd
          No CWD is being preset in interactive mode.
