Output

I need to understand difference between Write-Host which is what I normally use and Write-Output, Write-Error and Write-Debug. However according to Write-Verbose which writes to the verbose message stream. Reading about_CommonParameters shows that -Verbose is a Common Parameter, like -Debug and they can both be used with functions to control output. In Use PowerShell to Write Verbose Output - Hey, Scripting Guy! Blog - Site Home - TechNet Blogs this topic is discussed further. I have tried using -verbose on my whole script as in ps - Powershell script support for -verbose - Stack Overflow but had issues when my function also defined this use, so more work is needed here. In theory about_Functions_CmdletBindingAttribute should help.
