Use awk to change an IP format
Basically I am trying to run a standard output of IP address with a port number into another command but I need to change it from.
74.125.224.194.80 into 74.125.224.194:80
One command wants a period before the port the subsequent one wants a colon.
So is there anyway I can feed 74.125.224.194.80 into awk and have it just substitute a : in for the 4th period it finds?
I can find all kinds of ways to do global substitutions but I don't need all periods to have a : just the last one.
Thanks in advance!
