Thanks for your help on this @philltran! I merged in the update last night!

Thanks.

Last night, I noticed you wrote the test before I got to it.

Greping the terminus version makes sense. I was wondering what few commands we could run without a machine token.

@philltran looks like additional tests would probably be welcome in #1284
