$ git clone $URL
$ cd $PROJECT_NAME
$ git reset --hard $SHA1

再次返回到最近的提交

$ git pull

为了在线(远程)保存还原的提交，你必须强制执行origin:

git push origin -f

克隆一个git存储库，恰当地说，就是克隆整个存储库:没有办法只选择一个修订版本来克隆。然而，一旦你执行了git克隆，你可以通过执行checkout <rev>来检出一个特定的修订。

git clone -o <sha1-of-the-commit> <repository-url> <local-dir-name>

Git使用了origin这个词，而不是众所周知的revision

以下是手册$ git帮助克隆的一个片段

--origin <name>, -o <name>
    Instead of using the remote name origin to keep track of the upstream repository, use <name>.

总结一下(git v. 1.7.2.1):

在你想要回购的地方做一个常规的git克隆(得到所有的日期-我知道，不是想要的，我们正在那里) Git checkout <sha1 rev>你想要的rev Git重置——很难 Git checkout -b master

git克隆https://github.com/ORGANIZATION/repository.git(克隆存储库)

CD存储库(导航到存储库)
