I'm well aware of the "useless use of cat". I am not arguing that chittari's solution is the best (in fact, I find it evil; I would use jim's solution), but it could be an acceptable solution for some people. In this thread, jim also said, "So pick the tool and code you think applies. In UNIX there are usually several ways to do one thing."
