推荐答案

HEAD 是(直接或间接，即符号)对当前提交的引用.这是您已在工作目录中签入的提交(除非您进行了一些更改或等效)，并且它是在git commit"之上的提交.会做一个新的.通常 HEAD 是对其他命名分支的符号引用；此分支当前是签出分支，或当前分支.HEAD 也可以直接指向一个提交；这种状态称为分离的 HEAD"，可以理解为在未命名的匿名分支上.

HEAD is (direct or indirect, i.e. symbolic) reference to the current commit. It is a commit that you have checked in the working directory (unless you made some changes, or equivalent), and it is a commit on top of which "git commit" would make a new one. Usually HEAD is symbolic reference to some other named branch; this branch is currently checked out branch, or current branch. HEAD can also point directly to a commit; this state is called "detached HEAD", and can be understood as being on unnamed, anonymous branch.

和 @ 单独是 HEAD 的快捷方式，因为 Git 1.8.5

And @ alone is a shortcut for HEAD, since Git 1.8.5

ORIG_HEAD 是 HEAD 之前的状态code>，由可能具有危险行为的命令设置，以便于恢复它们.现在 Git 有 reflog 不太有用:HEAD@{1} 大致相当于 ORIG_HEAD(HEAD@{1} 总是最后HEAD的值，ORIG_HEAD是危险操作前HEAD的最后一个值.

ORIG_HEAD is previous state of HEAD, set by commands that have possibly dangerous behavior, to be easy to revert them. It is less useful now that Git has reflog: HEAD@{1} is roughly equivalent to ORIG_HEAD (HEAD@{1} is always last value of HEAD, ORIG_HEAD is last value of HEAD before dangerous operation).
