The point is that I would want it to work seamlessly between different flavors of *nix and FBSD. Since there seems to be a lack of consistency as to where 'Bash' is installed on different OSs, I find that using the notation I described works best and seems to improve the portability of the scripts. Since most of the scripts that I write are 'Bash' specific anyway, the fact that it would not work if Bash was not installed is of little importance.

By the way, this also works with Perl as you no doubt know. I cannot count how many times I have installed a Perl script and then had to modify the 'shebang' in order to get it to work in FBSD. I know that I could probably make some symbolic links or whatever; however, I feel that, that is the wrong way to get things to work properly.

Just my 2¢.
