Display IP addresses in tmux

I always forget my IP addresses and get tired of constantly running ifconfig or ip addr. Now I have tmux display them for me!


Here’s how I did it!

editing tmux.conf

Add the following lines to your tmux.conf file in order to display the IP addresses in the bottom right window.

set -g status-right "enp0s3: [#(get-ip.sh enp0s3)] enp0s8:[#(get-ip.sh enp0s8)] "
set -g status-right-length 50

The first line tells tmux to run my get-ip.sh script to print the IP addresses for interfaces enp0s3 and enp0s8. I’ve written about this script before but it is essentially just a wrapper for the command:

ip addr show <INTERFACE_NAME> | grep -m 1 inet | awk '{print $2}' | cut -d / -f 1

You can use either the builtin shell commands or download my get-ip script. Either will work fine.

The second line adjusts the padding so it looks nice in the tmux window.

hungry for more?
