Like I said, that's only a coincidence. If you move this script to another system it could well break. If you're using bash's features, always use #!/bin/bash. The purpose of that is to warn people that this script needs bash! Otherwise they won't know why it's breaking.

The #! is magic to tell execvp() what interpreter to use, so it is very important. Most of us use the same, newer shell for scripts and login, esp. as ksh and bash are forward compatible.
