- 同一路径下，源文件与目的文件不能重名。
- 源文件必须存在，且不为目录。
- 源文件路径支持“\*”和“？”通配符，“\*”代表任意多个字符，“？”代表任意单个字符。目的路径不支持通配符。当源路径可匹配多个文件时，目的路径必须为目录。
- 目的路径为目录时，该目录必须存在。此时目的文件以源文件命名。
- 目的路径为文件时，所在目录必须存在。此时拷贝文件的同时为副本重命名。
- 目前不支持多文件拷贝。参数大于2个时，只对前2个参数进行操作。
- 目的文件不存在时创建新文件，已存在则覆盖。
拷贝系统重要资源时，会对系统造成死机等重大未知影响，如用于拷贝/dev/uartdev-0 文件时，会产生系统卡死现象。

- mkdir后加所需要创建的目录名会在当前目录下创建目录。
- mkdir后加路径，再加上需要创建的目录名，即在指定目录下创建目录。
- mkdir后加参数，提供目录权限定制，目录逐级创建等功能。

> fatfs文件系统所有创建的文件和其挂载节点的权限属性保持一致，目前节点的权限只有用户读写权限，group和others权限不生效，
>
> 且只有读写位可设置，有rw和ro两种，因此mkdir在附加-m参数时，创建的目录权限仅有777和555两种，可执行权限也不生效。

## 使用指南<a name="section04"></a>
- 源文件路径支持“\*”和“？”通配符，“\*”代表任意多个字符，“？”代表任意单个字符。目的路径不支持通配符。当源路径可匹配多个文件时，目的路径必须为目录。
- 目的路径为目录时，该目录必须存在。此时目的文件以源文件命名。
- 目的路径为文件时，所在目录必须存在。
- 目的文件已存在则会覆盖。
## 使用实例<a name="section05"></a>
举例：
mv -i test.txt testpath/
mv test?.txt testpath/ （移动 test3.txt testA.txt test_.txt）
## 输出说明<a name="section06"></a>
**示例 1** 显示结果如下
```shell
OHOS:/$ touch test.txt
OHOS:/$ mkdir testpath
OHOS:/$ touch testpath/test.txt
OHOS:/$ mv -i test.txt testpath/
mv: overwrite 'testpath//test.txt' (Y/n):y
OHOS:/$ ls
bin etc proc storage testpath usr
dev lib sdcard system userdata vendor
OHOS:/$ cp testpath/test.txt ./
OHOS:/$ ls
bin etc proc storage test.txt userdata vendor
dev lib sdcard system testpath usr
OHOS:/$ mv -i test.txt testpath/
mv: overwrite 'testpath//test.txt' (Y/n):n
OHOS:/$ ls
bin etc proc storage test.txt userdata vendor
dev lib sdcard system testpath usr
```
**示例 2** 通配符使用
```shell
OHOS:/$ ls
bin etc proc storage test.txt testA.txt testpath usr
dev lib sdcard system test3.txt test_.txt userdata vendor
OHOS:/$ mv test?.txt testpath/
OHOS:/$ ls
bin etc proc storage test.txt userdata vendor
dev lib sdcard system testpath usr
OHOS:/$ ls testpath/
test.txt test3.txt testA.txt test_.txt

- ping命令用来测试到目的IP的网络连接是否正常，参数为目的IP地址。
- 如果目的IP不可达，会显示请求超时。
- 如果显示发送错误，说明没有到目的IP的路由。
- 命令需要启动TCP/IP协议栈后才能使用。
