Issue

  • I would like to get the IP address assigned to eth0. How do I display the IP address only?

Resolution

ifconfig will list the IP address assigned on the system.

Sometimes it is required to just find the IP address of a single interface. Its usually requires a script. In order to achieve this requirement, use several other commands along with ifconfig. These commands are grep and cut to acquire and print selected parts of lines/output.

ifconfig | grep -i "eth0" -A 1 | grep "inet addr" | cut -d " " -f 12 | cut -d ":" -f 2

Example output would look like the following:

ifconfig | grep -i "eth0" -A 1 | grep "inet addr" | cut -d " " -f 12 | cut -d ":" -f 2
