Powershell History Question

---

Hello! I am working with PowerShell Basics, Command History and Aliases course

I am in PowerShell Admin mode and ran the following:
Set-PSReadLineOption -HistoryNoDuplicates :$false (trying to toggle on/off)

And I get the following error message:

*Set-PSReadLineOption : A positional parameter cannot be found that accepts argument ':False'.
At line:1 char:1

• Set-PSReadLineOption -HistoryNoDuplicates :$false

•   + CategoryInfo          : InvalidArgument: (:) [Set-PSReadLineOption], ParameterBindingException
    + FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.PowerShell.SetPSReadLineOption*
  
  

Anyone have any ideas why I would be getting this error?

@Chris-Cartwright,

PowerShell is a game of patience...

It is all about the space in this case... Take a look at what I have highlighted below, which does work, and compare it to what you have that is not working...

Set-PSReadLineOption -HistoryNoDuplicates: $false

You can also use the Get-PSReadLineOption cmdlet to see the outcome of the change.

Good luck... and let me know if you have any other questions as you continue through the show...

Cheers,

Adam

@Adam-Gordon Thank you so much! I didn't even realize that, oh boy. I will keep the spaces in mind. Thanks again!!
