macos script

When I write a script, as the author I know what commands are going
tobe run, so it makes sense to set the PATH to all the directories that
are required. I don't know what the PATH in your shell is going to be,
so I can't assume that it will find all the commands.

Best practise suggests I should set the PATH to the full list of
required directories - that's just going to be less hassle for
everyone later on.
