我试着做git rebase，并在此过程中丢失了一个文件。这不是一个非常重要的文件，但我想了解发生了什么。
我想使用rebase命令将分支'master'合并到分支'learning'中。
以下是我的行动摘要：
git rebase高手，得到了冲突，解决了它，试图继续rebase，再次失败更多冲突，添加/提交一个未跟踪文件，再次失败rebase，尝试rebase --skip，失败，aborted rebase，最后做了git merge，这是成功的。
我在rebase期间提交的未跟踪文件（test.py）现已消失。
以下是我的行动的详细记录：

正如您所看到的，曾经在示例\基础知识中的test.py已经消失。
所以，我想了解两件事：为什么git rebase因冲突而失败，但是git merge很好？在rebase操作期间我提交的未跟踪文件发生了什么？
首先，这不会将master合并到learning：git rebase master将重播learning顶部的master。
其次，如果你在任何时候添加/提交了test.py，你可以使用find it back in the reflog。见“Query git reflog for all commits to a specific file”。
git rev-list --all -- test.py
第三，在篮板期间，你不应该承诺，only to add, then git rebase --continue。
