editor. I expect you ll be happier with the PowerShell ISE, or with a third-party editor like PowerGUI, PrimalScript, or PowerShell Plus. The ISE, in fact, makes scripting practically indistinguishable from using the shell interactively. By using the ISE s script pane, you simply type the command or commands you want to run, and then click the Run button in the toolbar to execute those commands. Click Save and you ve created a script without having to copy and paste anything at all.

The idea behind PowerShell scripts is, first and foremost, to make it easier to run a given command over and over, without having to manually retype it every time. That being the case, we should come up with a command that we want to run over and over again, and use that as an example throughout this chapter. I want to make this decently complex, so I ll start with something from WMI and add in some filtering, sorting, and other stuff. At this point, I m going to switch to using the PowerShell ISE instead of the normal console window, because the ISE will make it easier for me to migrate my command into a script. Frankly, the ISE makes it easier to type complex commands, because you get a full-screen editor instead of working on a single line within the console host. Here s my command:

Figure 17.1 shows how I ve entered this into the ISE. Notice that I selected the threepane layout by using the toolbar button set on the far right. Also notice that I formatted my command so that each physical line ends in either a pipe character or a comma. By doing so, I m forcing the shell to recognize these multiple lines as a single, one-line command. You could do the same thing in the console host, but this formatting is especially effective in the ISE because it makes my command a lot easier to read. Also notice that I ve used full cmdlet names and parameter names and that I ve specified every parameter name rather than using positional parameters. All of that will make my script easier to read and follow either for someone else, or in the future when I might have forgotten what my original intent was. I ve run the command by clicking the green Run toolbar icon in the ISE (you could also press F5) to test it, and my output shows that it s working perfectly. Here s a neat trick in the ISE: you can highlight a portion of your command and press F8 to just run the highlighted portion. Because I ve formatted my command so that there s one distinct command per physical line, that makes it easy for me to test my command bit by bit. I can highlight and run the first line independently. If I m satisfied with the output,

I can highlight the first and second lines, and run them. If it worked as expected, I can run the whole command. At this point, I can save the command I guess we can start calling it a script now! I ll save it as Get-DiskInventory.ps1. I like giving my scripts cmdlet-style verb-noun names. You can see how this script is going to start to look and work a lot like a cmdlet, so it makes sense to give it a cmdlet-style name.

enabled scripting by setting a more permissive execution policy. If you haven t done so, then you should flip back to chapter 14 and complete its hands-on lab so that scripts will run in your copy of PowerShell.
