Jacques B.Further to that last message, I re-ran it without the 127.0.0.1 portion of the sed command and it still worked. Reason being is that the result of the sed is saved to the variable as a single string (so the inet addr for eth0 followed by the inet addr line for the loopback). So when you do the pattern machine on the next line, only the very first NIC is retained. So the script is only suitable if you only have to worry about the first NIC. And like I said, the sed command could be as below and it will function the same. sed -n -e '/inet addr/p' If you need to deal with multiple NICs where you are interested in a NIC other than the first one listed, you'll have to script this differently.

thanks for the pointers all - this was being tested on a box that has more than 1 NIC hence the reason for the cut.
I need to get the third octect of the NIC address and depending on what that is a different automounter file is installed and if no network is recognised then a default is downloaded. I hope that clears up what i am trying to do and i will look at the options.
