Which terminal command to get just IP address and nothing else?

I'm trying to use just the IP address (inet) as a parameter in a script I wrote.

Is there an easy way in a unix terminal to get just the IP address, rather than looking through ifconfig?

Solution

  • You can write a script that only return the IP like:

    /sbin/ifconfig eth0 | grep 'inet addr' | cut -d: -f2 | awk '{print $1}'

    For MAC:

    ifconfig | grep "inet " | grep -v 127.0.0.1 | cut -d\  -f2

    Or for linux system

    hostname -i | awk '{print $3}' # Ubuntu 

hostname -i # Debian
