# Where is the \_\_ command?

One tricky thing is understanding that there are a certain number of commands that *come with PowerShell, \_while \_most* commands do not.

Every new version of PowerShell includes at least a few new commands. For example, Start-Job appeared for the first time in PowerShell v2, while Invoke-AsWorkflow was introduced in PowerShell v3.

What confuses people is that a new version of PowerShell also tends to correspond with a new version of the Windows operating system? and the OS itself comes with hundreds of commands. For example, you may have used Get-SmbShare for the first time in Windows Server 2012, which included PowerShell v3. But Get-SmbShare is *part of the operating system, not part of PowerShell.* That is, you won't have Get-SmbShare on every system that has PowerShell v3 or later, because the command isn't a "feature of PowerShell," it's a "feature of Windows."

So? where do you get commands?

Usually, with whatever product those commands are a part of. Want the Exchange Server commands? Install the Exchange Server admin tools. Want the Windows Server 2012 commands? Install the Remote Server Administration Toolkit (RSAT), which contains the server admin tools.

## 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://devops-collective-inc.gitbook.io/the-big-book-of-powershell-gotchas/where-is-the-__-command.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.
