Hi, I have a set of folders and I need to store the path of a particular one in a variable $folder. The set of folders are all children of a parent folder we'll call "parent". There are a bunch of folders with numeric names and one with a non numeric name. Here is an example of what is in the "parent" folder: 3.0.2.3 3.0.4.5 4.0.1.3 4.0.1.4 4.0.1.6 4.0.2.1 4.0.2.2 LOGS BUILD I want a powershell command that will store the path to the latest version folder (in this case "C:\parent\4.0.2.2") in my $folder variable. I think the best approach would be to filter the non numeric folders with a regex (something like "/d./d./d./d") and then use the pipeline and gci along with a command that would take the item at the bottom of the list. However I do not have much experience with the Powershell pipeline and was wondering if any talented Powershell users could help me with this problem. Thanks!

Try this... $LatestVersion=(get-childitem 'c:\temp' \| where-object {$_.PSIsContainer -and $_.Name -match '^\d'} \| Sort-Object Name \| select-object -last 1).Name $LatestVersion 4.0.2.2 In English: (Get all objects in c:\temp \| where object is a folder the and object name starts^ with a digit\d \| sort all the objects by name(default ascending) \| select the last object).Get the objects Name I hope the explanation helps... it took longer to write than the code ;-)

Rule #1: You should only use Format-Table as the final command in the pipeline and only when you're not using the output for anything else

Oops, you wanted the full path? Use .FullName at the end instead of .Name
