Gac Assemblies in Powershell

I first came across this on a post in StackOverflow about a month ago. The question was how to add assemblies to the Gac from a text file. Here is a (very) slightly modified solution from what I saw there:

sal -Name gacutil -Value $env:ProgramFiles'\Microsoft SDKs\Windows\V6.0A\bin\gacutil.exe'
filter gac-item { gacutil /nologo /i $_}
gc c:\list.txt | ?{$_ -like "*.dll"} | gac-item

The text file 'list.txt' would basically contain assemblies and their paths like:

C:\ICSharpCode.SharpZipLib.dll
c:\MyFile.dll
C:\MyAssemblyLocations\MyAssemblies\Test.dll

I was curious how easy it would be to just point to a folder and take all .dll files as opposed to looking at a text document. You can do that by modding the above script with this:

sl -Path $env:ProgramFiles\'MyBigProject\Bin'

foreach ($file in gci -Filter "*.dll" ) {
 gacutil /nologo /i $file.Name
}

Powershell really makes things like this very simple.
