Save Result from Get-ChildItem to an external variable

I am trying to find a way to store the result of Get-ChildItem to an external variable that I can use in another application.

Is this even possible? Every thread I have followed has resulted in failure.

Please help!

Example:

powershell.exe -command "Get-ChildItem -Path \\atl0wencd001.cead.prd\e$\EncoreNuGet\Packages\Insco.FicoRMA.Bin.&NUGET_ENV#.*.nupkg | Sort-Object LastAccessTime -Descending | Select-Object -First 1 |
