git branch master 9154301a47b33bdc273d8254c407792524367558


git checkout
 

$ 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。

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

# clone special tag/branch without history
git clone  --branch=<tag/branch> --depth=1 <repository>


# clone special revision with minimal histories
git clone --branch <branch> <repository> --shallow-since=yyyy-MM-ddTHH:mm:ss  # get the commit time
cd <dir>
git reset --hard <revision> 

如果不设置uploadpack，就不能获得没有历史记录的修订。在服务器端allowReachableSHA1InWant=true，而您可以为它创建一个标记并克隆特殊标记。

对于单个文件，当提交号已知时，可以使用wget onliner:
