# WSL

## Basic Operation

### Build a wsl

在微软商店中直接安装即可。\

以下的操作以 Ubuntu-18.04 为例，可以通过 `wsl -l` 查看自己安装的WSL。

### Run a wsl

```bash
wsl --distribution Ubuntu-18.04-20190707

or

wsl -d Ubuntu-18.04-20190707
```

### Remove a wsl

```bash
wsl --unregister Ubuntu-18.04-20190707
```

### Terminate a wsl

```bash
wsl -t Ubuntu-18.04-20190707

or 

wsl --terminate Ubuntu-18.04-20190707
```

### Back up a wsl

```bash
wsl -t Ubuntu-18.04-20190707 // 必须先停止要备份的WSL
wsl --export Ubuntu-18.04-20190707 path/to/your/backup
```

### Recover a wsl

```bash
wsl --import Ubuntu-18.04-20190707 path/to/your/wsl/location path/to/your/backup
```

注意这里有两个地址的参数，第一个是定义安装WSL在哪里，第二个是WSL的备份在哪里，**可以通过删除再重新定义存放WSL的路径的方式来减少WSL对C盘的占用**。
