How to print IP address using tcpdump and awk?

Question

I used this command but I am unable to print multiple values before each '.' This command is only printing the 192 of 192.168.113.2. I want to print the rest as well in the same line.

sudo tcpdump -i 2 -c 20 -n | awk -F '>' '{print $2}' | awk -F ':' '{print $1}' | awk -F '.' '{print $1}'

Please help.

What is the result of `sudo tcpdump -i 2 -c 20 -n` – Apr 01 '15 at 07:52 — , Apr 01 '15 at 07:52

You should never need to pipe awk into awk. – Apr 01 '15 at 08:14
