The problem is not at all related to PATH.  As with any shell that
allows aliasing and/or function definition, the aliases and functions
are not passed to children.  Only variables exported to the environment
are directly availble.  If he wants the bigfiles alias, he will have
to define it in the script, or source the script rather than execute it.
