Githug是一個用來了解、熟悉Git的一個非常好的游戲。

目前網(wǎng)站上收錄的都是之前只有55關(guān)的解題方法，沒有新增的rebase_onto這一關(guān)的內(nèi)容。現(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 topicbranch 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 somefunctionality which is found in next.o---o---o---o---o master\o---o---o---o---o next\o---o---o topicWe want to make topic forked from branch master; for example, because the functionality on which topic depends wasmerged 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 nextWe 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！
