Change that "grep" to "sed", and you will get a solution that works even on ancient machines, like HP-UX from 1990's. Grab msys, and you'd have your solution for Window-based systems as well. At the same time, installing "flex" and "cc" on a random machine would be much harder. Old Solaris boxes, for example, come without any C compilers, not to mention lexers. And finally, what are you going to do with the results? It is very likely that you'd want to pass them through sed/grep anyway. So you will have to worry about differences in shells and versions anyway. So sorry, I see no advantages of this, just disadvantages. Of course no one cares if you run them yourself, but posting them for other people is just evil.
