filename|xrootdurl
There are two ways to specify the xrootd file name.
- using the --server (-s) options
The xrootd server is specified using the --server option (-s also works) and the file name is the logical xrootd file name, e.g.:xrd.pl -s glast-rdr stat /glast/mc/testfile
- specify the full xrootd url:
xrd.pl stat root://glast-rdr//glast/mc/testfile
