HEAD〜vs HEAD ^ vs HEAD @ {}也称为波浪号vs插入符vs at符号 [英] HEAD~ vs HEAD^ vs HEAD@{} also known as tilde vs caret vs at sign

问题描述

HEAD是当前分支的指针.我已经见过HEAD祖先的各种记号，包括

HEAD is a pointer at the current branch. I have seen a variety of notations for ancestors of HEAD including

• HEAD~2
• HEAD^2
• HEAD@{2}
• HEAD~~
• HEAD^^

• HEAD~2
• HEAD^2
• HEAD@{2}
• HEAD~~
• HEAD^^

以上每一个到底是什么意思?该文件在哪里?

What does each of the above mean, exactly? Where is the documentation for this?

推荐答案

从文档此处.

• HEAD~2:2提交早于HEAD
• HEAD^2:HEAD的第二个父级，如果HEAD是合并的，否则是非法的
• HEAD@{2}:指git reflog
概述中的第3个清单
• HEAD~~:2提交早于HEAD
• HEAD^^:2提交早于HEAD

• HEAD~2 : 2 commits older than HEAD
• HEAD^2 : the second parent of HEAD, if HEAD was a merge, otherwise illegal
• HEAD@{2} : refers to the 3rd listing in the overview of git reflog
• HEAD~~ : 2 commits older than HEAD
• HEAD^^ : 2 commits older than HEAD

如果HEAD是合并的，则

If HEAD was a merge, then

• 第一父级是我们合并到的分支
• 第二个父级是我们合并的分支.

• first parent is the branch into which we merged,
• second parent is the branch we merged.

一些组合和同义词

First Parent    First Grandparent    Second Parent    Second Grandparent

HEAD~
HEAD^
HEAD~1          HEAD~2               HEAD^2           HEAD^2~        
HEAD^1          HEAD^^                                HEAD^2^
