Need suggestions for parsing a shell variable

Pauly · 01-15-2003, 05:21 PM

Hello,

I need some suggestions. I have a script that will ask the user for an ip address, which is entered by keyboard

ie: echo "What is your IP?"
read IPADDRESS

I then need to parse the IP address for the number in its 4th octet and store it to a another varilable. For example, if my IP is 192.168.128.4, I need to store the value 4 in a variable.

Cheers,

and thanks for any help offered!

fouthoctet=$(echo $ipaddress | awk -F. '{ print $NF }')

Note: Assumes a valid ip address.
