What does %U mean in Google Chrome command on MX Linux?

Question

I use MX Linux 17 (Horizon) and Google Chrome browser.

When I look at its command, it states, /usr/bin/google-chrome-stable %U . From this I understand Chrome executes this google-chrome-stable file with %U argument.

What does %U stand for? Where does this come from? I look at environment variable - by printenv command - and there is no such name listed on it.

Answer 1

It's more than likely an Exec for a Desktop Entry Specification .

%U - A list of URLs. Each URL is passed as a separate argument to the executable program. Local files may either be passed as file: URLs or as file path.
