dispalying IP address using echo

ravi_chobey · 03-19-2009, 05:42 AM

Using these commands,i can display the IP address of my address:

ifconfig eth0 | grep "inet addr" | cut -d: -f 2

awk 'print $2'.

But i dont have awk in my embedded system,and i want 2 use "echo".

How i could dsiplay ip address.

Regards,
Ravi

Perhaps if you don't have awk, you may have cut? It'll do something as simple as this without breaking a sweat.

Just echo the output of your ifconfig line:

echo `ifconfig eth0 | grep "inet addr" | cut -d: -f 2`

Or, easier to see using this format (same command though)
echo $(ifconfig eth0 | grep "inet addr" | cut -d: -f 2)

and adding the other cut as pwc101 suggested to clean it up:
echo $(ifconfig eth0 | grep "inet addr" | cut -d: -f 2| cut -d\ -f 1)

I'm sorry, I added pwc101's suggestion as an edit above and should have reposted.

echo $(ifconfig eth0 | grep "inet addr" | cut -d: -f 2| cut -d\ -f 1)
