This script was sent near a year ago by Reiserfs user to ReisrFS core
team--as a short sample that triggers some problem; and since that
time it was being used as one of the degradation tests when testing this
filesystem implementation. I supposed it's something well-known and
open source, but looking into it I've found next lines:

I have to investigate this copyright issue. But it's possible that
using supplied info you'll found the script before I'll finish the
investigation.
Anyway, It's doing nothing special:
1) removes anything in TARGET/stress directory;
2) counts MD5 sums on each file in the SOURCE tree;
3) starts N stress processes--each with his own target subdirectory
TARGET/stress/$p (p is the number of a particular stress process,
1<=$p<$N);
Each of stress processes in forever loop does the folowing:
a) creates its own TARGET/stress/$p subdirectory;
b) copies SOURCE subtree to TARGET/stress/$p;
c) recalculates all MD5 sums in TARGET/stress/$p and compares
them with those counted in SOURCE--complaining when
finds any difference;
d) removes TARGET/stress/$p subdirectory.
Cheers,
