I'm not sure what you're suggesting. I'm supposed to echo |cut ...? But I have a whole file, not just one line. So I have to cat ... |cut ... -- which is what I did. So what's your point?

I could keep the file first by saying:

  $ < combo_not.txt cut -c7-40 |sort |dups |wc -l
To which I reply, "Yuck!"

Perhaps we should stop here. You seem to have made this account just a few hours ago for the express purpose of poking at people's code fragments in this thread. You're making stylistic nitpicks (they don't affect correctness, do they?) and you're making them in a tone that I'm not sure I would take from Randal Schwartz himself (you actually edited http://news.ycombinator.com/item?id=4076556 to be ruder than the original). It's a drag, man.




cut takes a file as an argument. there's no need to start the line with <

   cut -c4-70 combo_not.txt|...
