           truncate, prepare, cat, tail, spaceinfo

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.

    -Z check if file is a ZIP archive and if yes list its content
    -C checksum every entry
locate [-n] [-r] [-d] [-m] [-i] [-p] <path>
    Get the locations of the path.
    -r refresh, don't use cached locations

    -d do a recursive, deep locate in order to find data servers
    -m prefer host names to IP addresses
