I'd agree with you that "grep ^" would be preferable _if_ we were to do this. But in your fork-less example, you are assuming that (1) "read" does not molest what is read, (2) "echo" is built-in, and (3) "echo" does not munge the parameter. Since I am one of old fashioned shell people (I readily admit that I used to have _fun_ with autoconf generated shell scripts), I'd love to continue shell skill show-offs, but for the purpose of updating this script, I would say a temporary file is much better than any of the alternatives around 1>&3. For one thing, it would make debugging the script while developing and tweaking it, _and_ while using it, much more pleasant. - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
