There are plenty of samples on the Internet about how to run PowerShell scripts from command line. However, I have huge trouble passing parameters, especially when the parameters contain space. After hours of trial and error, here is what I got it working.
powershell -NonInteractive -NoProfile -Command “& “””C:\Directory with Space\PowerShellScript.ps1“”” -NoSpaceParameter value1 -Time “””12/9/2010 7:00:00 PM“”” -Comment “””test abc“”””
Basically, the Command parameter is surrounded by one double quote, and to use double quote in PowerShell command itself, you need to use triple double quote. Have fun quoting. J
