The webpage has too much JavaScript and doesn't completely load under my slow network, so I'm not sure what are allowed to use in the game. But to an first impression, I think the game should encourage the participate to solve the problems in different approaches, although Unix pipe is powerful, sometimes a 5-line awk program or a "for loop" in bash is more effective.
