mkdir -p ~/.local/bin && wget -O ~/.local/bin/wslopen 'https://github.com/marveloo/wslopen/raw/main/wslopen' && chmod +x ~/.local/bin/wslopen
Or globally on the machine:
sudo wget -O /usr/local/bin/wslopen 'https://github.com/marveloo/wslopen/raw/main/wslopen' && sudo chmod a+x /usr/local/bin/wslopen
