As in2a5fcfae02and in3e67e5c992using /usr/bin/env allows bash to be looked up in PATH rather than being hard-coded. As with the previous changes the same arguments apply - distributions have scripts to rewrite shebangs on installation and they know what locations to rely on. - For tests/compilation we should rather rely on the user to have setup there PATH correctly. In particular this makes testing from git easier on NixOS where do not provide /bin/bash to improve compose-ability.
