I had too look it up :-) It's not just "useless use of cat", but also useless use of redirection in both cases. I guess sed can exit after it finishes processing the range (I don't know if it actually does), so feeding it the whole file is not need. OK, here's an improved patch.

Maybe we could use "type" rather than "which" because the former is a shell built-in. Or maybe we should hardcode the prefix on install. Anyway, it's out of scope of this patch. P.P.S. I hope that $toolpath doesn't start with "-". I could add "--" to the sed command line, but I'm not sure if BSD sed would like it. -- Regards, Pavel Roskin - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.htmlReceived on Wed Jun 15 10:33:31 2005
