No, but you increase your chances of a collision in the future. In practice, 8 or 9 characters tends to give unique commits. > How can I make sure that a shorter hash id will be unique? git-describe will find the shortest unique hash. But bear in mind that it may not be unique forever. -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
