I will concede that revert usually means both "discard current working dir changes" and "undo a previous change" in different circumstances. However, the number of times that "how do i discard my working dir changes" comes up on the list leads me to believe that you get the most out of using revert for this, since it is something that should be familiar to a user and undoing a previous commit is more rare. Of course, this is where I would use a DWIM-ism. "pyt revert -r commitish" would generate a reverse patch but "pyt revert <paths>..." would checkout from HEAD. "pyt revert" would just "git reset --hard". -Govind -- 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
