PowerShell Integrated Scripting Environment is a tool that can benefit all levels of users, which is why many developers and administrators use it almost exclusively when working with PowerShell -- often skipping the original console altogether.
With PowerShell ISE, which provides a graphical user interface (GUI) for writing and fixing PowerShell scripts, IT administrators and developers can write, edit and run PowerShell scripts and commands. It provides a more user-friendly way to work with the wide range of features available for creating and testing PowerShell codes.
For example, PowerShell ISE includes IntelliSense for autocompleting commands and for matching cmdlets, variables, parameters and other language elements. The GUI also provides quick access to a variety of snippets that make it easier to construct command logic, such as looping structures. In addition, admins get multiple execution environments, selective code execution and the ability to run commands from either the PowerShell script or the console pane.
What else can PowerShell ISE do?
PowerShell script development
PowerShell Integrated Scripting Environment provides many other features to support PowerShell script development, such as drag-and-drop editing, tab completion, block selection, syntax coloring, keyboard shortcuts and Unicode support. Plus, admins can open PowerShell script files by dragging them from Windows Explorer to the PowerShell ISE GUI. They can even extend the PowerShell Integrated Scripting Environment object model to customize the deployment and add functionality.
Admins can also use PowerShell Integrated Scripting Environment to troubleshoot and debug PowerShell scripts. Although this goes hand in hand with script development, sometimes admins must fix an existing script and want to use PowerShell ISE's debugging capabilities. Not only do they get features such as selective execution and multiple execution environments, but they can also set up breakpoints, step through code, check variable values and display call stacks. In addition, PowerShell Integrated Scripting Environment displays parsing errors as admins type.
Running complicated commands
Admins might also use PowerShell Integrated Scripting Environment when they want to run complex ad hoc commands and prefer to avoid the inherent clunkiness of the PowerShell console. With PowerShell ISE, they can type all their code in the script pane and then, when they're ready, run part or all of the code. This also makes it easier to tweak the script if admins need to run it multiple times, incorporating slight modifications with each execution.
PowerShell Integrated Scripting Environment is also useful as a learning tool. Someone new to PowerShell can benefit a great deal from built-in features, such as IntelliSense, snippet access and parse error displays.
