Hi monks,
My input is something like this: 
2345      IP   NAME.com         STATUS IPADDRESS1
2345/1243 IP Name-interface.com STATUS IPADDRESS2
2345/3213 IP NAME-interfce2.com STATUS IPADDRESS1
2345/1212 IP Name-interface3.com STATUS IPADDRESS3
4321      IP   CNAME.com         STATUS IPADDRESS_1
4321/1643 IP CName-interface.com STATUS IPADDRESS_1
4321/3673 IP CNAME-interfce2.com STATUS IPADDRESS_2

Here, ip address of 2345 and 2345/3213 are same &
ip address of 4321 and 4321/1643 are same.
I looked at some multi-line matching..but i'm not able to figure out
how it should be done. I was thinking of using hashes
with hashkey as the ipaddress however, since the number
of entries are too high, i don't think that is feasible as
it will consume lot of memory (that's what i think).
What should i use for this kind of input? Tie or hashes or normal arrays???
Update:
The output I was looking for was:
2345/3213 IP Name-interface2.com STATUS IPADDRESS2
4321/1643 IP CName-interface.com STATUS IPADDRESS_1

I'm sorry for the delay in reply...Outage et all...
The output should contain only those which have duplicate IP address
that too the duplicate one (second one).
