Windows PowerShell script debugging Windows Server 2016 introduced several improvements for script debugging introduced for Windows PowerShell: Break All Remote editing Remote debugging Job debugging Runspace debugging Remote Desired State Configuration debugging Let’s look into each element in more detail. Break All Break All is a very useful function to stop a script as it’s running so that we can dive into the debugger to find out how the script is running and what the current state of the variables and other elements are. Support has been included for both the Windows PowerShell console and the ISE. To use the debugger in a console session, press Ctrl+Break In the Windows PowerShell ISE, you can press Ctrl+B or, on the menu, click Debug and then click Break All. Remote editing With the current Windows PowerShell ISE, you can open and directly edit a file in a remote Windows PowerShell session. Using a new command called PSEdit, we can directly edit files locally and in remote sessions. The following code shows a sample in action: [Cloud01]: PS C:\> PSEdit C:\WinDemo\Get-ComputerInfo.ps1 When you execute PSEdit, it will open the file in the ISE where you can make changes and save them to the remote machine and reexecute the code. Remote debugging Extending on to the capabilities of remote editing, you can now debug a script running in a remote session with the ISE. The Set-PsBreakpoint cmdlet sets the breakpoint in the code and then you use the Write-Debug cmdlet to output some information for use in your scripts when you encounter a break point. This drops you into the debugger at that point to perform some additional work and look at the available information. Figure 5-1 shows this in operation. 138 CHAPTER 5 | Systems management
Figure 5-1: Sample code in the Windows Powershell ISE with remote debugging When a script encounters a breakpoint in a remote session, it will display a message indicating it has done so. Figure 5-2 illustrates a sample message. Figure 5-2: Breakpoint warning in a remote session Not all remote sessions will support a remote debug session, but when you connect to the remote session using the Connect-PSSession cmdlet, you will see the output shown in Figure 5-3. The output also lets you know whether it is available. Figure 5-3: Remote debug availability If remote debug is available, you can connect to the session by using the Enter-PSSession cmdlet, which connects you directly to the debugger Figure 5-4: Remote debugger in action Job debugging One useful function in Windows PowerShell is the ability to execute scripts as background jobs. These jobs can run without clogging up the main console screen, letting you proceed with additional tasks. This was fine, but these jobs could sometimes be difficult to troubleshoot and could require a lot of trial and error in order to develop robust scripts that could truly be run as jobs. Now, with Server 2016, Windows PowerShell introduces the Debug-Job cmdlet, which gives you the ability to debug these background jobs more effectively. Figure 5-5 shows this cmdlet being used. Note how Debug-Job shows you the line and character at which the job broke. 139 CHAPTER 5 | Systems management
