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:

```shell
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.
