I know that your gonna google things but go to the source.
It is not in these FAQs but do NOT forget to change the PATH variables
to a specific set of locations to find executables.... or you have a
mile high security hole/
See
[ruben-at-stat13 ~]$ set|grep PATH

That is standard on my usable shell - tooo wide. On shell scripts, it
is important to remember to set your environment and not depend on what
you inherit when you run it. In fact, that is probably true with all
programming, but it is an upfront and wide problem with shell scripts.
