Oops, I missed the trailing '.' in the regex there, and it probably needs double-quotes in case the inner expr fails to match anything. We could also use "test -gt" instead of the outer expr, which is more idiomatic shell. But it reports via exit code, so you'd need "&& echo 1" at the end. -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
