How do I find out what the current version of Firebase Tools is

From the node.js command prompt, using:

   this command

To get help with a specific command, type firebase help [command_name]

$ firebase -V

Gives a version number, but I don't know if it's the version number of Firebase Tools.

The only command for tools is:

tools:migrate [options]

Which is to: ensure your firebase.json format is up to date

How do I get the current version of firebase tools?
