I have once been on a system where the shells were in a different
directory. (I think it was a BSD system.) As I understand it
/usr/bin/env should be on every system, as a real file or a link. That
is why I use /usr/bin/env. But properly sh would be better instead of
bash. There are systems where bash is not installed.
