Interesting. I did the same investigation myself a few years back, but was frustrated by the lack of the -r flag for shuf(1). It seems that's been added at some point recently (though many of my systems do not have it--GNU coreutils percolates slowly through older Debian/Ubuntu versions. :))

Good to know things are still getting better in coreutils!

Oh, nice, on Fedora 23 beta, I can simulate die rolls

     shuf -r -z -n 100 -e 1 2 3 4 5 6;echo -e "\n"

And rolls of a non-transitive (Grime) die

     shuf -r -z -n 100 -e 3 3 3 3 3 6;echo -e "\n"

Which is timely. I sometimes forget how flexible the terminal prompt is...

It's pseudo-random though, right?

Oh, I'd imagine so. Good enough for illustrative purposes and for catching any gross errors in my arithmetic when analysing the games. Not good enough for anything 'real'.
