Scenario / Questions

I wanted to see colorized filenames when I typed dir in Powershell. So, I added the Set-ChildItemColor function from here to my profile file. I also added this line at the end of the profile file to override the dir alias:

Set-Alias dir Get-ChildItemColor

Now, when I open Powershell, I get this error:

Set-Alias : The AllScope option cannot be removed from the alias 'dir'.
At C:\Users\joe\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1:82
+ Set-Alias <<<<  dir Get-ChildItemColor
    + CategoryInfo          : WriteError: (dir:String) [Set-Alias], SessionStateUna
    + FullyQualifiedErrorId : AliasAllScopeOptionCannotBeRemoved,Microsoft.PowerShe

What is this AllScope? How do I remove that option to get colorized dir?

Find below all possible solutions or suggestions for the above questions..

Suggestion: 1

Use the -Option parameter of Set-Alias.

Set-Alias -Name dir -Value Set-ChildItemColor -Option AllScope

See Get-Help Set-Alias and Get-Help about_Scope for details.
