Client Admin

The client admin tools allow a user to do some file/directory operations in Xrootd: stat, rm, mkdir, checksum,.....

There are different tools:

  • xrdcmd (xrd.pl)
  • xrdls
  • xrd

xrdcmd Client admin tools

xrdcmd is wrapped around xrd.pl. It sets up the environment (LD_LIBRARY_PATH and PERL5LIB), If this environment is set by other means one could call xrd.pl instead of xrdcmd.

xrdcmd implements currently only a subset of all client admin tools.  The location of the script is:

    ~glastdat/bin/xrdcmd 

To get more information run :  ~glastdat/bin/xrdcmd -h

Examples> xrdcmd -s glast-rdr stat /glast/wilko/f1
size 37 onDisk 1 flags 48 modTime 1178659009 Tue May 8 14:16:49 2007 /glast/wilko/f1

> xrdcmd -s sulky48 dir /glast/mc

xrdls ls like

Xrootd does not provide the directory listing (ls) semantics as a file system does.

The xrdls is a command line tool that (by default) connects to all glast data servers and list
the directory content for each server.
It is implemented by using the standard unix ls command together with the xrootd preload library
