Windows PowerShell : Variables, Types, and Operators

Phil Pennington — Tue, 15 Sep 2009 15:44:00 GMT

Join James Brundage, PowerShell Test Team SDE, as he introduces Variables, Types, and Operators.

Windows PowerShell is a Windows command-line shell designed for ease-of-use not only by system administrators but also for application and system developers. The shell includes an interactive prompt and a scripting environment that can be used independently or in combination. PowerShell V2 is available by default with both R2 and Windows 7 and, via an optional update, previous versions of Windows.

For Developers specifically, Windows PowerShell in combination with the Windows Management Infrastructure (WinRM, WS-Management, WMI) provides a great way to automate server hosted solutions.   For example, if you implement all your administration logic via PowerShell, then layer the MMC GUI over the top (i.e. MMC calls PowerShell to get the work done) - you will have given your Enterprise customers the absolute best of all worlds; GUIs, scripting, and delegated, remote automation.

Unlike most scripting shells, which accept and return text, Windows PowerShell is integrated with the .NET Common Language Runtime (CLR) and the .NET Framework, and thus deals in .NET objects instead of just text strings. This fundamental change in the environment brings entirely new tools and methods to the management and configuration of Windows.   Application Developers may extend their solutions with custom PowerShell based object models that integrate seamlessly with platform management solutions.

Like many shells, Windows PowerShell gives you access to the file system on the computer. In addition, Windows PowerShell providers enable you to access other data stores, such as the registry and the digital signature certificate stores, as easily as you access the file system.

Version 2 of Windows Powershell introduces an array of new features including remote sessions, an integrated script environment, debugging tools, and much more.

Windows PowerShell V2 Modules

Phil Pennington — Thu, 09 Apr 2009 19:41:00 GMT

This video demonstrates converting a Windows PowerShell script to a Windows PowerShell module.

See more info at MSDN Code Gallery.

The video starts by introducing a simple script file, counter.ps1, with three functions and two variables.

The script file is dot sourced into the environment. All variables and functions are now in scope. The intent is to only have two of the functions in scope, with the rest being private implementation details.

Next, the file is renamed from counter.ps1 to counter.psm1 for the correct module extension. Using the Import-Module cmdlet, the module is loaded into scope. It is demonstrated that the variables are private, however all functions are public. This is shown using Get-Command -module counter to list the exported commands.

Before changing the module it is necessary to remove it from scope. This is accomplished using Get-Module | Remove-Module to pipe any modules (only one in this sample) to be removed.

In order to hide certain functions, it is necessary to specific which are public using Export-ModuleMember function_name. By specifying only the intended public functions, others remain private, only accessible from within the module.

Windows PowerShell V2 Sessions and Debugging

Phil Pennington — Thu, 09 Apr 2009 19:17:00 GMT

This video demonstration walks through the steps of creating and using sessions in Windows PowerShell v2. It also introduces the debugging functions such as working with breakpoints.

See additional information via MSDN Code Gallery.

Demo:

The Universal Code Execution Model means that you can run your cmdlets, scripts, and functions in any session, locally or remotely. A Windows PowerShell session is actually a persistent connection to the computer using the Windows Remote Management (WinRM) service. Creating sessions is performed using the New-PSSession cmdlet.

First, display the current process ID using the $pid environment variable. Next, create a new session on the localhost using New-PSSession.

The Invoke-Command cmdlet will cause script to be invoked on the given session, and in this case will simply output the value of $pid, the process ID, on the given session. This is a quick way to verify that the session is truly a different process from the original state.

The Get-PSSession cmdlet will display any running sessions. This does not include your terminal window which is not managed as a connection. Without running New-PSSession, the Get-PSSession cmdlet will not return any objects.

Next, execute the Some-Functions.ps1 script file containing a simple Square-Root function. Once invoked, you can execute the functions in the session, but not in the local terminal. The Import-PSSession cmdlet, run next, imports the sqrtAdvance function so it can be used locally.

Finally, the Remove-PSSession cmdlet is invoked to destroy the session and its underlying connection. Calling Get-PSSession confirms that it is no longer active.

Next, the video covers debugging using the Integrated Scripting Environment (ISE). The Set-PSBreakpoint cmdlet allows you to declare a breakpoint on a line, variable, or command. In the video, the breakpoint is placed on the variable "s1" which is the session variable. A breakpoint also specifies AccessMode, by default, Write. As soon as anything attempts to modify the value of "s1" code execution will break.

The existing script for working with sessions is started and as soon as the New-PSSession cmdlet is run, the breakpoint takes effect. ISE has a Debug menu which supports creating and managing breakpoints, stepping through and resuming code, and evening showing the call stack. The video steps through the code and demonstrates these features.

Windows PowerShell V2 Functions

Phil Pennington — Thu, 09 Apr 2009 19:01:00 GMT

Creating functions in Windows PowerShell is an easy way to extend the environment without resorting to code compilation and complicated deployment steps.

By using functions along with the right attributes and parameters, you can create first-class code extensions in PowerShell v2 without ever opening Visual Studio.
