Flip back to chapter 12 and refresh your memory on working with background jobs. For this lab, I d like you to create a background job that queries the Win32_BIOS information from two computers (use your computer s name and localhost if you only have one computer to experiment with). When the job finishes running, I want you to receive the results of the job into a variable. Then, display the contents of that variable. Finally, export the variable s contents to a CliXML file.

Take a few moments and skim through some of the previous chapters in this book. Given that variables are primarily designed to store something that you might use more than once, can you locate anything in the previous chapters where you might find a use for variables For example, in chapter 10 you learned to create connections to remote computers. What you did in that chapter was create, use, and close a connection more or less in one step; wouldn t it be useful to create the connection, store it in a variable, and use it for several commands That s just one instance of where variables can come in handy (and I m going to show you how to do that in chapter 18), so see if you can find any more examples.

So far in this book, we ve primarily been relying on PowerShell s native ability to output tables and lists. As you start to combine commands into more complex scripts, you ll probably want to gain more precise control over what s displayed. You may also have a need to prompt a user for input. In this chapter, you ll learn how to collect that input, and how to display whatever output you might desire.

How PowerShell displays and prompts for information depends on how PowerShell is being run. You see, PowerShell is built as a kind of under-the-hood engine. What you interact with is called a host application. The command-line console that you see when running PowerShell.exe is often called the console host. The graphical PowerShell ISE is usually called the ISE host or the graphical host. Other non-Microsoft applications can host the shell s engine, as well. You interact with the hosting application, and it passes your commands through to the engine. Whatever results the engine produces are displayed by the hosting application. Figure 16.1 illustrates the relationship between the engine and the various hosting applications. Each hosting application is responsible for physically displaying any output produced by the engine, and for physically collecting any input requested by the engine. That means output may be displayed, and input collected, in different ways. In fact, the console host and ISE use very different methods for collecting input: the console host presents a text prompt within the command line, but the ISE produces a pop-up dialog box with a text entry area and an OK button. I wanted to point out these differences because it can sometimes seem confusing to newcomers. Why would one command behave one way in the command-line

window but behave completely differently in the ISE It s because the way in which you interact with the shell is determined by the hosting application, and not by PowerShell itself.
16.2 Read-Host
PowerShell s Read-Host cmdlet is designed to display a text prompt and then collect text input from the user. You saw me use this for the first time in the previous chapter, so the syntax may seem familiar:
PS C:\> read-host "Enter a computer name" Enter a computer name: SERVER-R2 SERVER-R2
This example highlights two important facts about the cmdlet:
A colon is added to the end of the prompt. Whatever the user types is returned as the result of the command (technically, it s placed into the pipeline).
You ll often capture the input into a variable, which looks like this:
