Errors should go to stderr, so I imagine patches would be welcome.

In practice, each tool does its own thing because they evolved differently and from different authors. I think we are slowly converging on similar behavior, though, as people fix warts. As to exactly what that behavior is, I don't know that anybody has ever enumerated it exactly. Verbose status and progress reports, especially human readable ones, should probably always go to stderr. The "Switched to a new branch" message that started this thread is correct to go to stderr. If you want to silence the message but keep stderr open for actual errors, the right way is to use "-q". I tend to think the only thing that should go to stdout is the "main" output of a command. For something like "ls-files", that is obviously the list of files. For something like "checkout", which is about changing the repository and not about querying it, I think there is probably nothing that makes sense on stdout. -Peff -- 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
