# Ad-Hoc命令

`ad-hoc`命令是一些希望快速执行，但是不想保存以后使用的工作。也就是说，playbooks是可以反复执行的动作组合，而`ad-hoc`命令则是快速完成的命令。

## 并发和shell命令

以下指令以10个并发fork来完成重启分组`atlanta`服务器

```bash
ansible atlanta -a "/sbin/reboot" -f 10
```

默认情况下`ansible`使用当前帐号执行命令，如果需要使用不同帐号，添加`-u username`

```bash
ansible atlanta -a "/usr/bin/foo" -u username
```

如果希望执行`sudo`

## 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://huataihuang.gitbook.io/cloud-atlas-draft/devops/ansible/startup/adhoc.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.
