you have a typo in your awk command: the single quotes mark the awk-code:
awk '{ print $3, $6, $9 }'
A word of caution:
If you use this simple grep-command upon your out-file, you get not only
the Etot values for each of the printed MD steps, but also the Etot
averages and fluctuations (last two paragraphs in the out file); thus,
you probably want to omit the last two values in your graph.
Regards,
Anselm
