Limit depth of -recurse when using -get-childitem

Posted on 2007-03-29
Last Modified: 2008-01-09
Hello - I'm trying to dump out directories and owners for my helpdesk.
I found this script:
PS C:\> get-childitem \\server\c$\work  –recurse | get-acl |
select-object path,owner,accesstostring,group | export-csv c:\ACL.csv

from this site:

That's great, but I don't really need it to recurse the entire structure. All they want is the top two folder layers. Is there something equivalent to linux's --max-depth?  I also only need directories, not all objects, and really just want the folder owners, not the whole acl. If someone can assist with those additional items that would be great. I've only just looked at powershell for the first time today, so this is a learning process!

I'm running this on XP SP2, but the target will be Win2K and 2003 file servers.

It's all possible, but it would have to be a custom script, there's nothing built into limit recursion as far as I know.

I'm still a bit slow writing in PowerShell, but if you give me a day or so I'm sure I can come up with something.

Sorry for the wait. Basically you just want the Owner and the Path in a csv file?

I'm sure there's going to be a better / neater / easier way to do this.

Copy this to a .ps1 file and modify the $Start bit:

function do-recurse($Item, $i, $j)
      $Owner = $Item | Get-ACL | Select-Object owner

      Write-Output "$Item,$Owner"

      if ((get-item $Item).PSIsContainer -eq "True")
            if ($i -le $j)
            foreach ($ChildItem in (get-childitem $Item))
                        $Path = $Item + "\" + $ChildItem
                        if ((get-item $Path).PSIsContainer -eq "True")
                              do-recurse $Path $i $j

$Start = "<Path>"
do-recurse $Start 0 3

Once you've done that you must change the Execution Policy. I haven't signed the code because I'm not going to buy a digital signature so you must turn down the execution policy. I suggest setting it to Unrestricted so you can test this with:

Set-ExecutionPolicy Unrestricted

You can always turn it back up to the default, Restricted, after we're done.

After that you can execute the script above with:


And if you want the output in a file, do:

./<scriptname> | Out-File <FileName>

I'm afraid Export-CSV doesn't work for this at the moment, still trying to understand out to properly control output.

In the script you configure the maximum depth by modifying this line:

do-recurse $Start 0 3

Where 3 is the maximum depth. As I mentioned above I'm sure there are better ways to do all this, but it's tricky to find them.
