# pwunconv

用来关闭用户的投影密码

## 补充说明

**pwunconv命令** 与pwconv功能相反，用来关闭用户的投影密码。它会把密码从shadow文件内，重回存到passwd文件里。

### 语法

```
pwunconv
```

### 实例

```
pwunconv     # 关闭影子密码
cat /etc/passwd | grep test     # 发现密码已经在passwd文件中了
test:$6$nYOEWamm$bz07nlv/.RgJufb3FAqJJeULfwybzgxmrWqbk7O4vI0KsT6N.ujrh6dDIUcAJdfjksyuyAFDPIngZeD3cgcf.0:3001:3001::/home/test:/bin/sh

ls /etc/shadow     # 查看影子文件，提示没有这个文件或目录
ls: cannot access /etc/shadow: No such file or directory
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://hezhiqiang.gitbook.io/linux/ming-ling/pwunconv.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
