2 Meet PowerShell
This chapter is all about getting you situated and helping you to decide which PowerShell interface you’ll use (yes, you have a choice). If you’ve used PowerShell before, this material might seem redundant, so feel free to skim this chapter—you might still find some tidbits here and there that’ll help you down the line.
Also, this chapter applies exclusively to PowerShell on Windows, macOS, and Ubuntu 18.04. Other Linux distributions have a similar setup, but they will not be covered in this chapter. For those other installation instructions, you can get them right from PowerShell’s GitHub page at https://github.com/PowerShell/PowerShell#.
