Hi all.

I'm going to get the 80 port connected from client
netstat -na|grep 80|awk '{print $5}'
the output is
as below

I have 2 problems
1. how to get the uniq ip from output except for duplicated ip
2. how to get the separator ":" from the output
so first field is IP and second field is port

I need your help..!!!

>> how to get the separator ":" from the output

| tr ":" " "

>> how to get the uniq ip from output except for duplicated ip

| sort -u -k 1,1

So it could be:

netstat -n | awk '{ print $5}'| grep ":80 " | tr ":" " " | sort -u -k 1,1
