Linux中直接删除文件: rm <filename>

删除已经提交的文件会导致工作区与版本库不一致, 采用git status命令会显示:

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

    deleted:    test.txt

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

两种情况:

• 确认要在版本库中删除该文件:
  ①. git rm 从暂存区删除
  ②. git commit 确认删除文件

• 命令用错了,失误删除,需要恢复文件
  git checkout -- <filename>
  只能恢复到最后一次提交的版本
