Well, I get 18167, but that's not too far off.
And, remember, that the output of "df" might have changed in between times you ran "df" and you ran the "awk" command; there's only 7Mbytes difference. Did someone delete a 7Mbyte file? Send email? Finish a print job? Or... could be plenty of reasons for the used amount to go down.
Clarification - I just took the numbers above and used a calculator - my system would never produce numbers anything like that for any of my machines....
