ATTRIBUTE

optional argument, specifying a attribute to get or set. If no attribute is given, all attributes and corresponding values are displayed.

VALUE

if a attribute is given, a new value can optionally be assigned to it.

EXAMPLES

Show all attributes and values of a file:

gfal-xattr srm://endpoint.cern.ch/path/file

Show the value of a particular attribute:

gfal-xattr srm://endpoint.cern.ch/path/file user.status

Set a new value to an attribute:

gfal-xattr srm://endpoint.cern.ch/path/file user.status=new_value

Typically, you can get the transport urls (turls) with the user.replicas attribute:

srm://endpoint.cern.ch/path/file user.replicas
