Find out the IP address of eth0 and display IP only
Now you just wanted the IP address, use grep to get the IP:
$ /sbin/ifconfig eth0| grep 'inet addr:'
Output:
inet addr:192.168.2.1 Bcast:192.168.2.255 Mask:255.255.255.0
To get IP address from use cut command:
$ /sbin/ifconfig eth0 | grep 'inet addr:' | cut -d: -f2
Output:
192.168.2.1 Bcast
Finally remove Bcast with awk
$ /sbin/ifconfig eth0 | grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}'
Output:
192.168.2.1
