What happens if you run "open /Applications/*" I recently read in a blog post don't run open "/Applications/*" otherwise many tabs will reopen, But I ran it in Terminal and then suddenly all my apps in my Applications started to open my Mac started to heat up to 60 C and fans 1460 RPM I immediately force quit all the apps.What does "open Applications/*" do? and what is the meaning of *?
This command opens all apps in the /Applications folder. The * means everything in there. For example, to open all apps in /Applications that starts with S you would type open /Applications/s*. Since the * is by itself that means everything.
