PowerShell execute command with arguments safely

In my opinion this is the best way for executing external commands from PowerShell with arguments in a safe manner - via the use of an array to hold the arguments.

Consider this one a PowerShell gem to keep in the toolbox.

Note

The example below makes use of EchoArgs.exe - a small utility that simply echoes back arguments passed to it. Utility is part of the PowerShell Community Extensions, or the exe alone can be downloaded at https://ss64.com/ps/EchoArgs.exe.

Example

Export chrome bookmarks

This is a script to export bookmarks from the web browser Google Chrome to a users home drive in a Windows environment with clients and domain controllers. Most of the script comes from this article

Instruction

Double-click on the bat-file.
Go the home drive on the users new computer.
Double-click on openChromeFolder.bat which will take you to the chrome directory on that machiene.
Copy the file Bookmarks to the newly opened window.

	.Synopsis
	Creates a web server that will invoke PowerShell code based on routes being asked for by the client.

	.Description
	New-PSWebServer creates a web server. The web server is composed of a schema that defines the client's requests to routes where PowerShell code is executed.

	Under the covers, New-PSWebServer uses the HTTPListener .NET class to execute powershell code as requested, retrieves the results and sends data back through the httplistener web server framework.
