If you want to ensure that you have a particular flavor of shell then
don't use /bin/sh. The reason to use /bin/sh is that POSIX ensures it
exists but it doesn't have to be bash, even on Linux. For a generic
shell script use ksh syntax, you'll find that it gets you further and is
supported by bash.
