Learn about Windows PowerShell
Summary: Microsoft Scripting Guy, Ed Wilson, talks about Windows PowerShell best practices for simple scripts.
Microsoft Scripting Guy, Ed Wilson, is here. "Heyyyyy! Script it, baby!" The words of Scripting Cmdlet Style continue to echo through the house.

When I am working with Windows PowerShell, and the command begins to wrap to the second line, I start thinking about migrating to the Windows PowerShell ISE. If the line goes beyond two lines, I definitely move to the ISE. The reason is because command-line editing is rudimentary in the Windows PowerShell console, and also because the commands begin to be difficult to read. Also, as the length of command increases, my chance of executing the command correctly the first time decreases. If I pollute my Windows PowerShell console history with a bunch of commands that do not work properly, the whole thing becomes an exercise in futility.

It serves the same essential purpose: to allow me to quickly and efficiently execute simple Windows PowerShell commands.

That is an introduction to Windows PowerShell best practices related to quick scripts. Best Practices Week will continue tomorrow when I will talk about functions.
