19让工作区的文件恢复为和暂存区一样

场景

将仓库中工作目录文件修改后提交到了暂存区，此时继续修改工作目录文件，修改后发现使用暂存区的代码更好，此时希望将暂存区文件代码恢复到工作目录来。

实践

 G:\mygitea\GitLearn\learn03   master ± 
$ git status
On branch master
Changes to be committed:
  (use "git restore --staged <file>..." to unstage)
        modified:   test.txt

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


 G:\mygitea\GitLearn\learn03   master ± 
$ git diff --cached
diff --git a/test.txt b/test.txt

 提交到暂存区
+提交后对工作区进行变更.

此时要修改工作区的内容使其与暂存区内容一致，我们使用git checkout命令。如果要改暂存区的内容，我们使用git reset命令。

 G:\mygitea\GitLearn\learn03   master ± 
$ git checkout -- test.txt

 G:\mygitea\GitLearn\learn03   master ± 
$ git diff

 G:\mygitea\GitLearn\learn03   master ± 
$ cat test.txt
测试
提交到暂存区

执行命令后，工作区恢复成与暂存内容一致。
