参考git中的前一个/下一个提交？ [英] Referring to the previous/next commit in git?

问题描述

我已经看到git命令使用了诸如 HEAD〜之类的语法，但是我一直没能在Git 参考手册。

以下是我所了解的内容：< commit>〜< n> 指< commit> 之前的提交 步骤>< n> 是一个整数），而 commit〜只是意味着相同，而< n> 隐含地是一。

现在，这是正确的吗？在这种情况下，这是否总是有效？如果< commit> 是两个分支之间合并的结果，那么提交将会引用< commit>〜是否有一些对应的语法用于引用下一个提交或稍后的提交< n> 步骤？

解决方案

你在 Pro Git中的Acenstry参考：

• 〜用于获取第一个父母


• ^可以用于获取其他父母（例如，合并为^ 2）

但是，您不要没有简单的方法来引用下一个提交，即使有更多令人费解的方法来获得它。

I have seen git commands use a syntax such as HEAD~, but I haven't been able to find this syntax in the Git Reference Manual.

Here is what I have understood: <commit>~<n> refers to the commit <n> steps earlier than <commit> (where <n> is an integer number), and commit~ simply means the same and that <n> implicitly is one.

Now, is this correct? In that case, does this always work? What if <commit> is the result of a merge between two branches, which commit will then <commit>~ refer to? Is there some corresponding syntax for referring to the next commit or the commit <n> steps later?

解决方案

You have a very clear explanation of how this works in the chapter on Acenstry References in Pro Git :

• ~ is used to get the first parent
• ^ can be used to get the other parents (^2 for example for a merge)

But you don't have a simple way to reference the next commit, even if there are more convoluted ways to get it.
