There were a few of us that were having trouble using the shell script to generate files to excede the quotas set for the users during the final exam.
here is the command I was using:
> big; for i in 1 2 3 4 5 6 7 8 9 10 11 12; do du; cat filler >> big; done
No matter how many times I ran it, I would not exede the quota restriction for that directory.
so if you notice, the redirect to writes a file "big" the iterates 1 - 12 running du and appending it to "big"
then when I ran it again I rewrote big as an empty file "> big" and did the iterations again.
The thing to do was create the file, then run "for i in 1 2 3 4 5 6 7 8 9 10 11 12; do du; cat filler >> big; done" a couple time to append the file and make it bigger.
