Summary
This chapter focused on figuring out what version of PowerShell was installed and the many ways to start a PowerShell session. A quick introduction to PowerShell cmdlets showed that a lot of the command-line knowledge we have from DOS can be used in PowerShell and that aliases make this transition easier.
In the next chapter, we will look at the Get-Command, Get-Help, and Get-Member cmdlets, and learn how they unlock the entire PowerShell ecosystem for us.
