Rename-Item registry key from pipeline adds a space

Question

I'm just learning Powershell so this should be simple for some of you...

I have the followinng command to rename multiple registry subkeys:

Get-Childitem -Path HKLM:\SOFTWARE\SCCMINV\OfficeAddins\Addins -Name -Recurse | % { rename-item $_ "HKLM_ $_" }

The problem is that the new key name results in a space between the string text and pipeline input, such as:

"HKLM_(space)Search.OutlookToolbar"

Any suggestions?

Your code, as posted, DOES include a space between 'HLKM_' and '$_'

{ rename-item $_ "HKLM_ $_" }

If this IS just a typo, you could use the following code, which trims any spaces from $_ prior to inserting it into the string to replace the {0} token.

{ rename-item $_ ( "HKLM_{0}" -f $_.Trim() ) }
