When I run this command:

blt sync:refresh:all

I get the following output:

And I expected this to happen:
I expected it to complete and end at a command prompt with a finished VM.

I am not able to reproduce this issue, but I understand that multiple people have encountered it. I have tried PHP 5.6 and PHP 7, and I'm running the same version of OS X as you are.

Are you able to reproduce this issue on BLT 8.x? Also, what shell are you using?

[danepowell]

I just encountered this after upgrading to 8.9.0. Ubuntu / bash. It also occurs on 8.x-dev.

Reading #1862, it seems like the goal is for this to be interactive but it's not for some reason.
