This should be interesting.
During The Scripting Games, I observed (and in some cases made) a great many comments that I'm lumping under the name "Purity Laws."
- You shouldn't use a command-line utility like Robocopy in a PowerShell script.
- You shouldn't use .NET classes in a PowerShell script.
- You should map a drive using New-PSDrive, notÂ net use.
And so on. You see where I'm going: there are folks out there who feel as if the only thing that goes into a PowerShell script is Pure PowerShell. Which is odd, because it isn't an approach the product team actually gave much value. They spentÂ extra time making sure the shell could use .NET, and could run external utilities - why not use them, if they work and get the job done?
A counterargument involves maintenance and readability. External commands, for example, are harder to read, may not be well-documented, and don't work consistently with the rest of PowerShell. .NET classes are hard to discover, and force you into a very "programmer-y" approach. Some environments might not want the extra overhead - even if it means giving up functionality.
So where do you come down on this debate? I'd really love someÂ detailed recommendations.Â What's right forÂ your environment, and most importantlyÂ why?Â Are there any facts or situations that would sway you to the other side of the argument?
