Can you post exact numbers? It's only faster if the commit is present very early in the log. The reason is probably that because of the '-q' option it does not actually read the full log, but breaks out as soon as it's found a match. In my test I had an elapsed time of ~0.5 sec (versus 1 sec for Junio's test). And here's a grep for the very first commit: $ time git log --pretty=format:%H | grep -q 48404cb50b0b547 real 0m0.010s user 0m0.000s sys 0m0.012s -- 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
