May I suggest a slightly gentler name like shutdownall?

shutdownall

@eed3si9n done!

I understand this is not a real sbt command like shutdown, but it might be confusing that to shutdown one you don't need -- but to shutdown all, you need --. My suggestion would be to pretend this is a command and call it:

$ sbt shutdownall

WDYT?

Also, could there be a Windows parity for this feature?

I like it, thanks for thinking outside the box and consistency in usage. I'll also see about the windows parity.

@eed3si9n updated, removed the -- and added .bat support

Note with environment variable SBT_NATIVE_CLIENT=true, you will also need to supply --server for this to work.

$ sbt --server shutdownall
shutdown 1 sbt processes
