Trial #13: Why is Write-Verbose not Doing Anything?

Problem:

I made a script with some functions in it and the built in PowerShell verbose switch is doing absolutely nothing.

    ./MyScript.ps1 -verbose #I'm having to revert to write host to have a clue what is happening!

Solution:

Give PowerShell a chance - it’s made it pretty easy for you - just put cmdletbinding attribute above your parameters in any given script.

    [cmdletbinding()]
    param()

Powershell will then give you some free common parameters including -verbose.

• Debug (db)
• ErrorAction (ea)
• ErrorVariable (ev)
• InformationAction
• InformationVariable
• OutVariable (ov)
• OutBuffer (ob)
• PipelineVariable (pv)
• Verbose (vb)
• WarningAction (wa)
• WarningVariable (wv)

Thanks to Ed Wilson, Microsoft Scripting Guy, for providing a solution to my problem and leading me into this interesting topic in his post.

There is a lot more you can do with the Parameter Binding Attribute
