移动文件（git mv）

使用git mv命令将mian.c移动为main2.c

$ git mv main.c main2.c

D:\Git\test (master -> origin)
$ git status
On branch master
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

        renamed:    main.c -> main2.c

可以看出，git识别出了这一次重命名操作，这一条操作相当于

$ mv main.c mian2.c
$ git rm main.c
$ git add main2.c

如果你手工更改一个文件的名称，则git会认为是删除了原文件，而新增了一个文件。例如手工将main.c改名为main2.c

$ 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:    main.c

Untracked files:
  (use "git add <file>..." to include in what will be committed)

        main2.c
