首先我初始化一个仓库，并且提交了一个文件：

情景一

在工作区对index.html做了一些修改，还没有add到暂存区，并且暂存区没有index.html的修改。

我们先来执行 git status 来查看下状态：

$ git status
On branch master
Your branch is ahead of 'origin/master' by 2 commits.
  (use "git push" to publish your local commits)
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

    modified:   index.html

no changes added to commit (use "git add" and/or "git commit -a")

这里git告诉你可以使用命令git checkout -- <file>... 可以丢弃工作区的修改（目前还在工作区），对应的GitKraken上的操作为：

执行操作之后你会发现，之前工作区的修改已经没了，现在index.html回到了和版本库一样的状态。

情景二

对index.html做了一次更改，然后add到暂存区，接着又对它做了更改

$ git status
On branch master
Your branch is ahead of 'origin/master' by 2 commits.
  (use "git push" to publish your local commits)
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

    modified:   index.html

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

    modified:   index.html

此时我们执行：git checkout --index.html 就会撤销工作区的更改，回到和暂存区一样的状态：

$ git status
On branch master
Your branch is ahead of 'origin/master' by 2 commits.
  (use "git push" to publish your local commits)
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

    modified:   index.html
