I solved the problem with this:

for f in *.rod; do echo $f; cut -f5 $f | sort -k1.3n | uniq | wc -l; done

Hi Tange,

I find the GNU Parallel interesting. I'm not exactly a computing person, can you clarify the following for me:

1. what is the difference between GNU parallel and multi-threaded process? For example, if my program allows multi-threading and I run 4 threads in my quart-core computer, am I right to assume that the GNU parallel is not going to make any difference?
2. If I already running some other process and still specify -j+0, what is going to happen?

Thank you.
