== isn't a valid comparison operator for the test command. See the FreeBSD
manpage, or the Posix docs:
http://www.opengroup.org/onlinepubs/9699919799/toc.htm. You need to use =.
Certain Linux distributions use bash as /bin/sh, which shortcuts the test
command internally and allows bash extensions, even in bourne-shell mode.
Debian and Ubuntu use dash instead of bash, and this script would fail on
them as well.
