十一. mv命令
//改名
[root@VM_0_15_centos test]# ls
a hello.txt son son2 target
//改名情况一：
//mv file（存在） file1（不存在） 为file改名
[root@VM_0_15_centos test]# mv hello.txt bye.txt
[root@VM_0_15_centos test]# ls
a bye.txt son2 son3 target
//改名情况二：
//mv dir（存在） dir1（不存在） 为dir改名
[root@VM_0_15_centos test]# mv son son3
[root@VM_0_15_centos test]# ls
a hello.txt son2 son3 target
//移动
//移动情况一
//mv file（存在） dir（存在）
//结果：文件file移动至dir中
[root@VM_0_15_centos test]# ls
a bye.txt son2 son3 target
[root@VM_0_15_centos test]# tree a
a
`-- hello.txt
0 directories, 1 file
[root@VM_0_15_centos test]# mv bye.txt a
[root@VM_0_15_centos test]# ls
a son2 son3 target
[root@VM_0_15_centos test]# tree a
a
|-- bye.txt
`-- hello.txt
0 directories, 2 files
//移动情况二
//mv dir（存在） dir1（存在）
//结果：dir移动到dir1中
[root@VM_0_15_centos test]# ls
a son2 son3 target
[root@VM_0_15_centos test]# mv a son2
[root@VM_0_15_centos test]# ls
son2 son3 target
[root@VM_0_15_centos test]# tree son2
son2
|-- a
| |-- bye.txt
| `-- hello.txt
`-- son
`-- hello.txt
2 directories, 3 files
//移动情况三
//mv file（存在） file1（存在）
//结果：file文件覆盖掉file1文件，file文件会被删除掉
