So now it fails only on 512 byte block size filesystems?
Perhaps rather than an exact match, a "within_tolerance" match could
be done on the relevant fields?
i.e something like:
blksused=`{requota cmd} | awk '/fsgqa/ { print $3 }'`
_within_tolerance "blocks used" $blksused 16 1
If you wanted to get really fancy, the tolerance could be set
depending on filesystem type and block size, but I don't think that
is really necessary....
Cheers,
Dave.
