It looks like you're running prettyping via macOS's `/bin/sh`, which is a strange way to run it. I'd suggest `./prettyping google.com` or `bash ./prettyping google.com`.
I believe that `/bin/sh` is a launcher that may or may not launch `/bin/bash` (bash-3.2, the last version of bash included in macOS) in posix mode, depending on your configuration....
@danielb2 prettyping should work now in bash's "posix mode", either in my branch or once PR #44 is accepted.
