问题描述
有些 Git 命令以父级作为修订；其他(例如 git revert)，作为父编号.两种情况下我怎样才能找到父母?
Some Git commands take the parent as a revision; others (such as git revert), as a parent number. How can I get the parents for both cases?
我不想使用图形日志命令，因为这通常需要向下滚动一棵长树才能找到第二个父级.
I don’t want to use the graphical log command as that often requires scrolling down a long tree to find the second parent.
推荐答案
Simple git log 调用合并提交显示其父级的缩写哈希:
Simple git log <hash> called for a merge commit shows abbreviated hashes of its parents:
$ git log -1 395f65d
commit 395f65d438b13fb1fded88a330dc06c3b0951046
Merge: 9901923 d28790d
...
git 根据他们的数量输出父母:第一个(最左边的)哈希是第一个父母，依此类推.
git outputs parents according to their number: the first (leftmost) hash is for the first parent, and so on.
如果你想要的只是哈希值，两个等效的选择是:
If all you want is just the hashes, the two equivalent choices are:
$ git log --pretty=%P -n 1 <commit>
$ git show -s --pretty=%P <commit>
git rev-list 也可以显示父母的哈希值，尽管它会首先列出提交的哈希值:
git rev-list can also show the parents' hashes, though it will first list the hash for a commit:
$ git rev-list --parents -n 1 <commit>
如果你想检查父母，你可以直接用克拉来指代他们作为^1和^2，例如:
If you want to examine the parents, you can refer to them directly with carats as <commit>^1 and <commit>^2, e.g.:
git show <commit>^1
这确实概括了；对于章鱼合并，您可以将 n 父项称为 ^n.您可以使用 <commit>^@ 来引用所有父项，尽管这在需要单次提交时不起作用.附加后缀可以出现在第 n 父语法之后(例如 ^2^、^2^@)，而它们不能在 ^@ 之后(^@^ 无效).有关此语法的更多信息，请阅读 rev-parse 手册页.
This does generalize; for an octopus merge you can refer to the n parent as <commit>^n. You can refer to all parents with <commit>^@, though this doesn't work when a single commit is required. Additional suffixes can appear after the n parent syntax (e.g. <commit>^2^, <commit>^2^@), whereas they cannot after ^@ (<commit>^@^ isn't valid). For more on this syntax, read the rev-parse man page.
