我如何从我目前的状态转向在某个承诺上拍摄的截图?

如果我做 git 登录,那么我会得到以下输出:

$ git log

Yep, more blah blah.

我如何转向11月3日的承诺,即承诺0d1d7fc?


当前回答

这很大程度上取决于你指的是“逆转”。

暂时转换到另一个承诺

# This will detach your HEAD, that is, leave you with no branch checked out:
git checkout 0d1d7fc32

git checkout -b old-state 0d1d7fc32

要回到你所在的地方,只需检查你所在的分支再次(如果你做了变化,如往常交换分支时,你将不得不处理它们,你可以重新设置,把它们扔掉;你可以打破,支票,打破,把它们带到你身边;你可以承诺它们到一个分支,如果你想要一个分支在那里。

硬删除未发表的承诺

如果,另一方面,你真的想摆脱你从那时起所做的一切,有两种可能性。

# This will destroy any local modifications.
# Don't do it if you have uncommitted work you want to keep.
git reset --hard 0d1d7fc32

# Alternatively, if there's work to keep:
git stash
git reset --hard 0d1d7fc32
git stash pop
# This saves the modifications, then reapplies that patch after resetting.
# You could get merge conflicts, if you've modified things which were
# changed since the commit you reset to.

如果你混乱,你已经扔掉了你的地方变化,但你至少可以通过重新设置回到你以前的地方。

下一篇: 与新承诺发布的承诺

# This will create three separate revert commits:
git revert a867b4af 25eee4ca 0766c053

# It also takes ranges. This will revert the last two commits:
git revert HEAD~2..HEAD

#Similarly, you can revert a range of commits using commit hashes (non inclusive of first hash):
git revert 0d1d7fc..a867b4a

# Reverting a merge commit
git revert -m 1 <merge_commit_sha>

# To get just one, you could use `rebase -i` to squash them afterwards
# Or, you could do it manually (be sure to do this at top level of the repo)
# get your index and work tree into the desired state, without changing HEAD:
git checkout 0d1d7fc32 .

# Then commit. Be sure and write a good message describing what you just did
git commit

其他回答

我发现最不复杂的方式,把一个分支转向任何特定的承诺,在那里你不能改变历史,就是:

查看承诺或分支您的愿望转向. 编辑.git/HEAD 并更改转向您转向的分支。

如如:

echo 'ref: refs/heads/example' > .git/HEAD

如果你做 git 状态,你应该看到你所在的分支和你想转向的分支之间的所有变化。

如果一切都看起来很好,你可以承诺. 你也可以使用 git diff revert..example 确保它是相同的。

为了完全清理编码器的目录,我们使用了:

git add -A .
git reset --hard HEAD

只是 git reset --hard HEAD 会摆脱修改,但它不会摆脱“新”文件。在他们的情况下,他们偶然在某个地方随机拖动了一个重要的文件夹,所有这些文件都被 Git 处理为新的,所以一个 reset --hard 没有修复它。

但是,为了完整性,我也想展示这些其他替代解决方案,也可以用来逆转一个承诺(在这个意义上,你创建一个新的承诺,阻止了以前的承诺的变化,就像Git的逆转一样)。

替代方案1:硬和软重组

这是查尔斯·贝利(Charles Bailey)的解决方案的一个非常轻微修改的版本,以便在Git中通过SHA的Hash转向一个承诺吗?

# Reset the index to the desired commit
git reset --hard <commit>

# Move the branch pointer back to the previous HEAD
git reset --soft HEAD@{1}

# Commit the changes
git commit -m "Revert to <commit>"

这基本上是通过使用软重组将离开指数/重组区域的前承诺的状态,然后你可以承诺。

替代方案2:删除现有树,并用新树取代

git rm -r .
git checkout <commit> .
git commit

类似于替代 #1,这重复了当前工作副本中的 <commit> 状态. 首先需要做 git rm 因为 git checkout 不会删除自 <commit> 以来添加的文件。

如果你想修正某些错误的最后一个承诺一个好的替代品将是使用 git 承诺 - 更改命令. 如果最后一个承诺没有提到任何参考,这将是技巧,因为它创造一个承诺与相同的父母和最后一个承诺. 如果没有提到最后一个承诺,它将只是被拒绝,这个承诺将是最后一个承诺。

这很大程度上取决于你指的是“逆转”。
