Ah - that's it! My /bin/sh is symlinked to /bin/bash. I believe following the instructions for installing a GNU Radio SDK is why I made that change:
"On some distributions (e.g. Ubuntu), PyBOMBS can run into shell issues. To avoid those problems, it is recommended to run the following command
before continuing, and choose "no" in the prompted dialogue:
$ sudo dpkg-reconfigure dash"
Is it expected that changing the system's default shell would break scripts?
