使用git mv命令将mian.c移动为main2.c

$ git mv main.c main2.cD:\Git\test (master -> origin)$ git statusOn branch masterChanges to be committed:  (use "git reset HEAD 
    
     ..." 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 statusOn branch masterChanges not staged for commit:  (use "git add/rm 
    
     ..." to update what will be committed)  (use "git checkout -- 
     
      ..." to discard changes in working directory)        deleted:    main.cUntracked files:  (use "git add 
      
       ..." to include in what will be committed)        main2.c
