Git move n向前承诺 [英] Git move n commits forward

问题描述

我正在一个存储库的提交C(我刚刚做了一个git checkout hash_of_C).

I'm in commit C (I just did a git checkout hash_of_C) of a repository.

A - B - C - ...<19>... - D - ...<many many commits> - Z

哪个Z是master分支中的最后一个提交

Which Z is the last commit in the master branch

现在，我想向前进行20次提交.

Now, I want to move forward 20 commits.

推荐答案

如果我正确理解，您想向前移动20个C提交，而Z是master分支上的最后一个提交，但不一定是从20个提交开始C.

If I am understanding correctly, you want to move forward 20 commits from C, and Z is the last commit on the master branch but not necessarily the 20th commit from C.

从C做

C > git checkout $(git rev-list --topo-order HEAD..master | tail -20 | head -1)

它将结帐20个向前的提交如果存在.

It will checkout the 20 commit forward if it exists.

我对此并不完全有信心，但这就是它的作用.

I am not totally confident about it but here is what it does.

git rev-list --topo-order HEAD..master 将为您提供从C到master的所有提交列表/每行一个.

git rev-list --topo-order HEAD..master will give you list of all the commits from C to master/one per line.

当我们做尾巴-20时，我们基本上想从底部20行开始从列表中切出一块.如果我们以-1开头，我们将进一步削减列表，仅获取最高的项目.这样，我们从当前提交中获取第20个项目.

When we do tail -20 we basically want to cut a piece out of this list from bottom 20 line up. If we do head -1, we cut the list further, taking only the top item. This way we get the 20th item forward from the current commit.

哪个是 $(git rev-list --topo-order HEAD..master | tail -20 | head -1)
