git 重写历史

• 重写最后一次提交的commit

   git commit --amend

• 修改多个历史

  git rebase -i HEAD~3

  命令执行后结果如下：

  

  pick f7f3f6d changed my name a bit
  pick 310154e updated README formatting and added blame
  pick a5f4a0d added cat-file
  
  # Rebase 710f0f8..a5f4a0d onto 710f0f8
  #
  # Commands:
  #  p, pick = use commit
  #  e, edit = use commit, but stop for amending
  #  s, squash = use commit, but meld into previous commit
  #
  # If you remove a line here THAT COMMIT WILL BE LOST.
  # However, if you remove everything, the rebase will be aborted.
  #

  

  将你想修改的每一次提交前面的pick改为edit

  edit f7f3f6d changed my name a bit
  pick 310154e updated README formatting and added blame
  pick a5f4a0d added cat-file

  当你保存并退出编辑器，Git会倒回至列表中的最后一次提交，然后把你送到命令行中，同时显示以下信息：

  

  $ git rebase -i HEAD~3
  Stopped at 7482e0d... updated the gemspec to hopefully work better
  You can amend the commit now, with
  
         git commit --amend
  
  Once you’re satisfied with your changes, run
  
         git rebase --continue

  

  然后

  $ git commit --amend
  
  $ git rebase --continue

  ok一切搞定。
