Githug是一個(gè)用來(lái)了解、熟悉Git的一個(gè)非常好的游戲。

目前網(wǎng)站上收錄的都是之前只有55關(guān)的解題方法，沒(méi)有新增的rebase_onto這一關(guān)的內(nèi)容?，F(xiàn)在Githug一共有56關(guān)。現(xiàn)將新增的42關(guān)的解答內(nèi)容更新如下：

第42關(guān)的題目如下:

Name: rebase_onto
Level: 41
Difficulty: **

You have created your branch from `wrong_branch` and already made some commits, and you realise that you needed to create your branch from `master`. Rebase your commits onto `master` branch so that you don't have `wrong_branch` commits.

通過(guò)查找，在git rebase中有以下用法：

Here is how you would transplant a topic branch based on one branch to another, to pretend that you forked the topic
       branch from the latter branch, using rebase --onto.

       First let's assume your topic is based on branch next. For example, a feature developed in topic depends on some
       functionality which is found in next.

               o---o---o---o---o  master
                    \
                     o---o---o---o---o  next
                                      \
                                       o---o---o  topic

       We want to make topic forked from branch master; for example, because the functionality on which topic depends was
       merged into the more stable master branch. We want our tree to look like this:

               o---o---o---o---o  master
                   |            \
                   |             o'--o'--o'  topic
                    \
                     o---o---o---o---o  next

       We can get this using the following command:

           git rebase --onto master next topic

所以，第42關(guān)的通關(guān)方法如下：

 git rebase --onto master wrong_branch readme-update

祝通關(guān)順利！
