# You must run this script from an "elevated terminal", that means right click on Windows Terminal and "Run as Administrator".
# Then run it with `sudo wsl-ip.sh` from within WSL.

# Remove existing wsl.local lines
sed -i '/wsl.local/d' /etc/hosts
sed -i '/wsl.local/d' /mnt/c/Windows/system32/drivers/etc/hosts

# Add to WSL hosts file
echo "`ifconfig | sed -En 's/127.0.0.1//;s/.*inet (addr:)?(([0-9]*\.){3}[0-9]*).*/\2/p'` wsl.local" >> /etc/hosts
