Quick and dirty one, I was looking for an alternative to ipconfig /all that worked with invoke-command. This works on IPv4 and IPv6 and includes both tunnel and cluster adapters. This does not work on Server 2008 R2 even with WMF 5+.

Get-ChildItem -Path source -Recurse -Directory | Remove-Item

There's five useful commands when it comes to controlling your output in PowerShell (in my experience): Out-File, Export-Csv, Format-Table aka ft, Format-List aka fl, and Out-Null. These are all pretty self explanatory. Out-File saves your output to a regular text file (and does not translate it from a PowerShell object …

New-Item -ItemType file <filename>
# Example: creating the PowerShell profile. -Force is required to make the full path.
New-Item -ItemType file $profile -Force
New-Item can also …

When it comes to remoting in PowerShell, there's two main options: Invoke-Command (good) and Enter-PSSession (bad, but necessary sometimes).
