I don't think there is a problem but some very minor points:

1)On the first run the .aux file doesn't exist so the copy will give rise to
an error message. No harm done. You could correct that by testing for the
existence of the .aux file before copying:

If [ -e "${basefname}.aux" ] ; then .... fi

and a similar thing for the .auxcopy at the end.

2)Since the .aux file will be trashed anyway why not use /bin/mv rather than
/bin/cp in both cases so you don't have to add anything to the /bin/rm
command? Again, trivial.

3)Why not just add a second pdflatex processing line at the bottom? That
will make everything right at the cost of a small amount of time. If you
always do bibliographies add the bibtex call and then two more pdflatex
calls. ...

Good Luck,
