Awk Query

[user57]

Could someone please assist with the below. I am attempting to print pairs of devices which are colon seperated.

Each A and B device is associated with a "V" adapter.

If there are no devices associated with a "V" adapter it is to be ignored.


input:

V0:A1:B1:A2:B2
V1: :
V2:A1:B1:A2:B2:A3:B3
V3:A1:B1:A2:B2:A3:B3:A4:B4


Desired output:

V0:A1:B1
V0:A2:B2
V2:A1:B1
V2:A2:B2
V2:A3:B3
V3:A1:B1
V3:A2:B2
V3:A3:B3
V3:A4:B4

Also, in future do not open two threads with the same subject.
My initial view was these were duplicate, and I was about to delete one.
