How can I display the IP address of an interface?

Solution 1:

Try this (Linux)

/sbin/ifconfig eth1 | grep 'inet addr:' | cut -d: -f2| cut -d' ' -f1

or this (Linux)

/sbin/ifconfig eth0 | awk -F ' *|:' '/inet addr/{print $4}'

or this (*BSD)

ifconfig bge0 | grep 'inet' | cut -d' ' -f2

or this (Solaris 10)

ifconfig e1000g0 | awk '/inet / {print $6}'

Obviously change the interface name to match the one you want to get the information from.

On a Linux system:

hostname --all-ip-addresses

will give you only the IP address.

On a Solaris system use:

ifconfig e1000g0 | awk '/inet / {print $2}'
