Test-Path folders and remove

[localpct]

We have a collection of folders we get from a script, and the engineers don't like to keep this list up to date. I'm looking for a way to query if the folders exist, and if they do, add them to a new variable

Code: [Select all] [Expand/Collapse]

1.     foreach ($folder in $Shares)
2.  
3.             {
4.  
5.             test-path $folder
6.  
7.             if ($true){
8.  
9.             $NewShares+= $folder;
10.  
11.             }
12.  
13.             }

The problem, my results are

\\share\folder\\share\folder2\\share\folder5

It's not breaking them into individual objects
What I'm looking at getting is

\\share\folder
\\share\folder2
\\share\folder5

You can create an array variable to store the result from the "foreach" statement.

[array] $myFolderlist = $null;

$myFolderlist = foreach ($folder in $Shares)
{
if ((test-path $folder) -eq $true){
$folder;
}
}

$myFolderlist

Hope this helps!

Yes it does.

Can I use this in a workflow? It would be much quicker to run through my list of 50 folders with a work flow. When I run the below script, it returns nothing

Code: [Select all] [Expand/Collapse]

1. Workflow TestWorkFlow{
2.  
3. foreach ($folder in $myFolderlist)
4.  
5. {test-path $folder}
6.  
7. }

This is how to code this kind of coding pattern, PS will accumulate to an array automatically.

Code: Select all

$NewShares = foreach($folder in $Shares){
     if(test-path $folder){$folder}
}

Or even easier:

Code: Select all

$NewShares = $Shares | Where-Object{test-path $_}

A workflow will not give much speed with such short code.

Thanks to both of you. I have it working as I need it..

Just too bad workflows won't work :/

Workflows will work. My indication is that they may not be all that much faster although this would depend on your network.

Here is an old script that I found in my junk box.

Code: Select all

workflow Test-WFConnection {
    param(
        [string[]]$Computers
    )

    foreach -parallel ($computer in $computers) {
        Test-Connection -ComputerName $computer -Count 1 -ErrorAction SilentlyContinue
    }

}

$computers = Get-ADComputer -Filter * | Select -Expand Name
Test-WFConnection $computers

Got it.. It's definitely not a significant increase. Thanks for taking the time to go back to this
