Networking :: Create A Script To Display DNS And IP Address Information?

I have been playing with Linux consistently for a couple of months now. I've been a Windows sys. admin for most of my career, so Linux is pretty strange for me. I started off with computers way back with the TRS-80 and then eventually moved to DOS systems. So the command line interface (CLI) of Linux was not completely alien to me, yet my lack of knowledge on the syntax and commands is holding me back. I have come a long way.

Recently I needed to play around with some DNS settings and one of the commands I used frequently in Windows, IPCONFIG /ALL, doesn't have a direct relative that displayed the same information. If you run ifconfig, it doesn't return the DNS servers you are currently using. You have to run a separate command to retrieve that information.

What I have done is created a super simple script that displays the network information for my primary LAN adapter, which is ETH0 in my case. After that, it shows the domain and name server information. Then it pauses for 20 seconds before closing the terminal window.

Here are the contents of the script file:

ifconfig -a eth0
cat /etc/resolv.conf
sleep 20

I simply right-clicked the Linux desktop, choose Create Document, Empty File. I named it something like Network Info. Then I opened it and put this information in it, saved it, and closed it. I renamed the file and added a .sh extension to the end which makes it into a script file. Next, right-click the script and go to properties. In the Permissions tab, check the box next to Execute: Allow executing file as a program. Then click close.

To run the script, just double-click the icon and then click Run In Terminal at the prompt. The terminal window opens, displays the information, and exits after 20 seconds. If you need it longer than that or need a different interface (such as wlan0 for your wireless), you can change or even add that in.

This was all done in Ubuntu 10.10. I know it is very simple and very straight forward and welcome thoughts and feedback about simpler ways to do this. For me, the old-school Windows admin, it's a baby step in the right direction. I am really enjoying learning the Linux OS.
