This first script displays my internal IP address and my WAN IP address by simply extracting that information from ifconfig whenever I type "myip" in the terminal. Here is the script.
function myip() # get IP adresses
{
MY_IP=$(/sbin/ifconfig eth0 awk "/inet/ { print $2 } " sed -e s/addr://) \ MY_ISP=$(/sbin/ifconfig
eth0 awk "/P-t-P/ { print $3 } " sed -e s/P-t-P://)
}
This displays:
External IP:
xxx.xxx.xxx.xxx
Internal IP:
192.168.0.97
This second function displays my machine statistics, file system space available, memory stats and IP information, when I type "ii" in the terminal. Here is the function:
function ii() # get current host related info
{
echo -e "\nHello ${RED}$USER"
echo -e "\nSystem information:$NC " ; uname -a
echo -e "\n${RED}Machine stats :$NC " ; uptime
echo -e "\n${RED}Storage stats :$NC " ; df -h grep -v varrun grep -v varlock grep -v udev grep -v\ devshm
echo -e "\n${RED}Memory stats :$NC " ; free -m
echo -e "\n${RED}Local IP Address :$NC" ; ifconfig grep
'inet addr:' grep -v '127.0.0.1' cut -d: -f2 awk '{ print $1}'
echo -e "\n${RED}ISP Address :$NC" ; wget www.whatismyip.com/automation/n09230945.asp -O - -q
echo ""
}
You'll notice that in this script, my outside WAN IP is pulled from a website instead of from the ifconfig command. Here is the output:

I apologize that not everything is lined up correctly, it's due to the layout in blogger. The output lines up fairly cleanly in the terminal.
Enjoy!

You'll get better results with the layout if you format code and terminal output in a monospaced font such as courier.
