Xrootd does not provide the directory listing (ls) semantics as a file system does.
The xrdls is a command line tool that looks a little bit like an ls. By defaults it
loops over all xrootd data servers and obtains a directory listing for each of them.
xrdls [-l] [dataserver] directory
It is implemented by using the standard unix ls command together with the
xrootd preload library. Using the long listing the user and group name are
not meaningful. The time shown is the mtime.
Below are some examples
> xrdls /glast/mc
==listing from server sulky02
ServiceChallenge TonyTest junk
==listing from server sulky47
DC2 ServiceChallenge junk
==listing from server sulky48
