It's probably more elegant to use #!/bin/bash at the beginning of your 
scripts, as we don't actually have a Bourne shell on our Macs. In 
additional to its superset of commands `bash` does, I believe, behave 
slightly differently from traditional `sh`; if invoked as `sh` Bash 
_should_ behave as `sh`, however I am not aware that this has been 
demonstrated. [1]

Consequently beginning scripts with `#!/bin/bash` is acknowledging that 
you haven't tested it with the last-seen-in-the-70s Bourne shell (which 
is undoubtedly still available on some systems, and of which I believe 
there are feature-compatible variants still maintained).

Stroller.
