Hi,
When I connect to a Cisco router and issue the show ip interface command, the output is similar as follows:

Interface                  IP-Address      OK? Method Status                Protocol
Ethernet0/0               192.168.12.1      YES NVRAM  up                    up     
Serial0/0                  unassigned      YES NVRAM  administratively down down   
Ethernet0/1               unassigned      YES NVRAM  administratively down down   
Loopback0               1.1.1.1            YES NVRAM  up                    up     

Will anyone please tell me how to select text in block instead of line,  so that I can get the IP address on all interface, in gnome-terminal as well as in vim.
Many thanks!
