Especially in Linux, it's common to prefix scripts with #!/bin/bash
which won't work in FreeBSD, because it's #/usr/local/bin/bash there.
Linux has no problem running #!/bin/sh scripts because there's a
symlink /bin/sh -> /bin/bash.

My advice for maximum interoperability and compatibility between Linux
and UNIX: If you're not using any bash specific techniques in your
scripts, start them with #!/bin/sh instead of #!/bin/bash.

The sh shell is the UNIX standard scripting shell, while Linux's
one is bash.
