Thanks Jack! Not only did that clarify the role of "-c", but it solves those pesky "cannot execute binary file" messages I was getting.

who the user really is that is executing the script. As I said before, perl
is pretty good for this:

jkelly-mp:~ root# perl -e 'print getlogin()."\n";'

It seems that $USER always represents the non-root user who initiated the installer, even if it is running with admin/root privileges. So, for example, the following postinstall script works fine for me, creating a file with the name of that user on their Desktop:

su $USER -c "touch ~/Desktop/$USER"

This also works for running /usr/bin/mdimport, which hopefully solves Geoff's original question.

Thanks all for your help.
