Colorizing Get-Childit
I just installed and used https://github.com/Davlind/PSColor which was painless. It supports PSGet so you can install easily with Install-Module PSColor
to get it.
The objects aren't transformed so they still support piping. (It's using the New-CommandWrapper
mentioned above)
It also supports other things like select-string.
