xrdfs - xrootd file and directory meta-data utility

xrdfs [--no-cwd] host[:port] [command [args]]
command: help, chmod, ls, locate, mkdir, mv, stat, statvfs, query, rm, rmdir, truncate, prepare, cat, tail, spaceinfo

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.

No CWD is being preset in interactive mode.
