Yesterday, I needed to get my server’s network information for a Bash script I was writing. Here are the commands so I don’t forget. They were tested using Fedora 12.
Get IP address:
ifconfig eth0 | awk '/inet / {print $2}' | awk -F: '{print $2}‘
Get MAC address:
ifconfig eth0 | awk '/HWaddr/ {print $5}'
Get network gateway IP address:
route -n | awk '/^0.0.0.0/ {print $2}'
