如何在git中提交之间前后移动？ [英] How do I move forward and backward between commits in git?

问题描述

我正在做一个 git bisect 并且在到达有问题的提交之后，我现在试着向前/向后迈出一步，以确保我处于正确的位置。

我知道 HEAD ^ 会在历史中倒退，但还有另一条捷径让我前进未来的特定提交）如下所示：

  A  -  B  -  C（HEAD） -  D  -  E  -  F 
  

我知道我的目标是 F ，并且我想从 C 转换为 D 。

注意： git：如何在提交之间来回移动，我的问题稍有不同，并且没有在那里回答

$ b $ b

解决方案

我已经尝试了一下，这看起来有助于向前浏览：

  git checkout $（git rev-list --topo-order HEAD..towards | tail -1）
  

其中指向是提交的SHA1或标签。

解释：

• $（）表示：获取当前 HEAD 和向 commit的所有提交（不包括 HEAD ），并按照优先顺序对它们进行排序（例如默认情况下在 git log 中 - 而不是按时间顺序排序这是奇怪的 rev-list ）的默认值，然后取最后一个（ tail ），即我们想去。


• 这是在子shell中计算的，并传递给 git checkout 来执行结帐。 / ul>
  
  

  您可以定义一个可作为参数访问的函数 - 在您的 .profile 文件中预期为别名，以向前导航提交：
  
  

   ＃在Git提交层次结构中，向特定的提交
  ＃前进使用：
  ＃gofwd v1.2.7 
  ＃当参数没有被指定时什么也不做。 
   gofwd（）{
   git checkout $（git rev-list --topo-order HEAD ..$ *| tail -1）
  } 
   
   ＃回到Git commit层次结构
  ＃用法：
  ＃goback 
   alias goback ='git checkout HEAD〜'
    

  
  

  I am doing a git bisect and after arriving to the problematic commit, I am now trying to get a step forward/backward to make sure I am in the right one.

  I know of HEAD^ to go backwards in history but is there another shortcut to get me forward (towards a specific commit in the future) like so:

  A - B - C(HEAD) - D - E - F
  

  I know that my target is F and I want to move from C to D.

  NOTE: this is not a duplicate of Git: How to move back and forth between commits, my question is slightly different and is not answered there

  解决方案

  I've experimented a bit and this seems to do the trick to navigate forwards:

  git checkout $(git rev-list --topo-order HEAD..towards | tail -1)
  

  where towards is a SHA1 of the commit or a tag.

  Explanation:

  • the command inside $() means: get all the commits between current HEAD and towards commit (excluding HEAD), and sort them in the precedence order (like in git log by default -- instead of the chronological order which is weirdly the default for rev-list), and then take the last one (tail), i.e. the one we want to go to.
  • this is evaluated in the subshell, and passed to git checkout to perform a checkout.

  You can define a function accessible as a parameter-expecting alias in your .profile file to navigate forward towards the particular commit:

  # Go forward in Git commit hierarchy, towards particular commit 
  # Usage:
  #  gofwd v1.2.7
  # Does nothing when the parameter is not specified.
  gofwd() {
    git checkout $(git rev-list --topo-order HEAD.."$*" | tail -1)
  }
  
  # Go back in Git commit hierarchy
  # Usage: 
  #  goback
  alias goback='git checkout HEAD~'
