Get LAN IP address

This is a utility script to display your local network address.

Intended use case is anywhere you need an unambigious reference to your current LAN IPv4 whether this is another script or just to make sure.

Add a file to your ~/.local/bin folder, name it check-network, make it executable

mkdir -p  ~/.local/bin
touch ~/.local/bin/check-network
chmod +x ~/.local/bin/check-network

Edit the file and paste below content - be aware that the ttf_icons() does not display correct.

The function looks like this in Sublime Text. The font used is the package ttf-font-icons available in the Manjaro repo.
