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?
