Yes you can. Just start the script with "#!/bin/sh", as usual.
When invoked that way, Bash and other shells are POSIX-compliant
in this area.
To what level of posix... if they are compliant to the original level
then they might have the original behavior that allowed rm -r . to work.
if they are the 2003 version, then a different way, .. bleh.
I overly worry about things that don't occur, but get caught
by things I didn't worry enough about. So it doesn't really
matter. I just preferred simplicity to the ever changing
posix.
