31
32       -t, --timeout TIMEOUT
33              global timeout for the execution of the command. Command is  in‐

45       -4     forces Gfal2 to use IPv4 addresses only. (Option valid only  for
46              GridFTP protocol)
47
48       -6     forces  Gfal2 to use IPv6 addresses only. (Option valid only for
