PowerShell equivalent of LINQ Any()?

Question

I would like to find all directories at the top level from the location of the script that are stored in subversion.

In C# it would be something like this

Answer 1

My approach now was:

gci -r -force `
    | ? { $_.PSIsContainer -and $_.Name -match "^[._]svn$" } `
    | select Parent -Unique

---

The reason why

select-object {$_.Directory}

doesn't return anything useful is that there is no such property on a DirectoryInfo object. At least not in my PowerShell.

To elaborate on your own answer: PowerShell can treat most non-empty collections as $true, so you can simply do:

$svnDirs = gci `
    | ? {$_.PsIsContainer} `
    | ? {
        gci $_.Name -Force `
            | ? {$_.PSIsContainer -and ($_.Name -eq "_svn" -or $_.Name -eq ".svn") }
        }
