4 Useful Way to Know Plugged USB Device Name in Linux
|
||||||
|
在Linux系统里识别USB设备名字的4种方法
|
||||||
|
============================================================
|
||||||
|
|
||||||
|
对于初学者来说，在Linux系统里你必须掌握的技术之一就是识别出插入系统里的各种设备。这也许是你的系统硬盘，外部的存储设备或者是可移动设备，比如USB设备或SD闪存卡等。
|
||||||
|
|
||||||
|
现如今，使用USB设备来传输文件是十分常见的事，对于那些喜欢使用命令行的新手来说，当你需要格式化USB设备时，学会使用不同的方法来识别USB设备名是非常重要的。
|
||||||
|
|
||||||
|
如果你插入一个设备到你的系统中，尤其是在桌面环境下，比如USB设备，它会自动挂载到一个指定目录,正常情况下是在/media/username/device-label目录下，之后你就可以进入到该目录下访问那些文件了。然而，在服务器上就不是这么回事了，你必须手动挂载这个设备，并且指定一个挂载点。
|
||||||
|
|
||||||
|
Linux系统使用/dev目录下特定的设备文件来标识插入的设备。你会发现该目录下的某些文件，包括/dev/sda或者/dev/sha表示你的第一个主设备，每个分区使用一个数字来表示，比如/dev/sda1或/dev/sha1表示主设备的第一个分区等等。
|
||||||
|
|
||||||
|
```
|
||||||
|
$ ls /dev/sda*
|
||||||
|
```

列出Linux系统下所有的设备名
|
||||||
|
|
||||||
|
现在咱们来使用下面一些特殊的命令行工具找出设备名：
|
||||||
|
|
||||||
|
### 使用df命令来找出插入的USB设备名
|
||||||
|
|
||||||
|
查看插入你系统里的每一个设备及对应的挂载点，你可以使用下图中的df命令检查Linux系统磁盘空间使用情况：
|
||||||
|
|
||||||
|
```
|
||||||
|
$ df -h
|
||||||
|
```
|
||||||

使用df命令查找USB设备名
|
||||||
|
|
||||||
|
### 使用lsblk命令查找USB设备名
|
||||||
|
|
||||||
|
你也可以使用下面的lsblk命令（列出块设备）来列出插入你系统里的所有块设备：
|
||||||
|
|
||||||
|
```
|
||||||
|
$ lsblk
|
||||||
|
```

|
||||||
|
|
||||||
|
### 使用fdisk工具识别USB设备名
|
||||||
|
|
||||||
|
fdisk是一个功能强大的工具，用于查看你系统中的所有分区表，包括所有的USB设备，使用root权限执行如下命令：
|
||||||
|
```
|
||||||
|
$ sudo fdisk -l
|
||||||
|
```
|
||||||

列出块设备的分区表
|
||||||
|
|
||||||
|
### 使用dmesg命令来识别出USB设备名
|
||||||
|
|
||||||
|
dmesg是一个重要的用于打印或者控制内核环形缓冲区的命令。环形缓冲区是一种数据结构，它存放着内核操作数据的信息。
|
||||||
|
|
||||||
|
运行如下的命令来查看内核操作信息，它同时也会打印出USB设备的信息：
|
||||||
|
|
||||||
|
```
|
||||||
|
$ dmesg
|
||||||
|
```
