What's Powershell?

It's a command-line shell from microsoft, that's built-On Windows. It's also Open-source and written in C#, you can see the source code on github.

We will be using version 5.1, if you don't know your version, try:

```powershell

$PSVersionTable.PSVersion

```

Command-lets

The name means "Command-Let" came from the pattern used to name all the commands in powershell, where first we have some verb and then we have a noun (e.g.: _Get-Command_)

We can see all the commands available by typing:

```powershell

Get-Command -CommandType Cmdlet

```

Getting help

To get help from any command, you just need to use `Get-help x` where x is the command you're trying to know about.

Getting examples

If you want to get some examples about the command usage, you can use `Get-help x -Examples`.

Open on browser

To see the help command in the official microsoft's page, you need to add the flag `-Online`, the full command would be like `Get-help x -Online`.

Open in another window

`-ShowWindow` -> It will open another GUI window.

Also, you can use the command `Update-help` to get the new version of the commands documentation.
