How to find the bundle ID of a Mac app

I was running a script and I had the need to find the bundle ID of one app I had installed.

The bundle ID is the string that looks like a domain, but written in the opposite way.

Like com.apple.finder or com.microsoft.VSCode.

Here’s the script you can use:

osascript -e 'id of app "Finder"'

osascript is a tool that runs AppleScript. That AppleScript code, id of app "Finder", asks the Mac for the bundle ID of the app with the name we passed to it.
