Attempting to use two arrays as variables to search file names (powershell) - arrays

Question

I need to search multiple (named) folders on multiple servers for files matching a specific date and copy those files to a local folder using Powershell. The number of folders are not the same size arrays as the number of servers. I.e. I need \server1\interfacefolders\folder1, \server1\interfacefolders\folder2, \server2\interfacefolders\folder1, \server2\interfacefolders\folder2, etc.
I have the following set up as arrays/variables preparing for this, I thought "nested" foreach loops would work, but it bombs out...any ideas how to get started on this?:
[string[]]$ProdServerArray = "server1", "server2", "server3"
[string[]]$InterfaceArray = "folder1", "folder2" "folder3" do {
$date = Read-host "Enter date (MM/DD/YYYY) : " } while ($date -as [datetime] -isnot [datetime])
$date = $date -as [datetime]
$destination = new-item c:\GetFilesResults\$($date.toshortdatestring().replace("/","-")) -type directory
$path = foreach ($ProdServer in $ProdServerArray)
{
$folder = foreach ($Interface in $InterfaceArray)
{
$file = "\\$path\InterfaceFolder\$folder\*"
if ("$file".LastWriteTime -gt $date.date)
{
Copy-Item -Path $file.fullname -Destination $destination
}
}
}

Answer 1

to build the full folder names from those two arrays, you can use two nested foreach loops. once you have the values, you can build the paths via something like the -f string format operator.
i left out the rest of your code since it does not appear to pertain to the question you asked. [grin]
$ProdServerArray = 'serverAAA', 'serverBbBbBb', 'server_CCC'
$InterfaceArray = 'folder1', 'folder2', 'folder3', 'folder666'
foreach ($PSA_Item in $ProdServerArray)
{
foreach ($IA_Item in $InterfaceArray)
{
'\\{0}\InterfaceFolders\{1}' -f $PSA_Item, $IA_Item
}
'=' * 30
}
output ...
\\serverAAA\InterfaceFolders\folder1
\\serverAAA\InterfaceFolders\folder2
\\serverAAA\InterfaceFolders\folder3
\\serverAAA\InterfaceFolders\folder666
==============================
\\serverBbBbBb\InterfaceFolders\folder1
\\serverBbBbBb\InterfaceFolders\folder2
\\serverBbBbBb\InterfaceFolders\folder3
\\serverBbBbBb\InterfaceFolders\folder666
==============================
\\server_CCC\InterfaceFolders\folder1
\\server_CCC\InterfaceFolders\folder2
\\server_CCC\InterfaceFolders\folder3
\\server_CCC\InterfaceFolders\folder666
==============================

First of all, you are missing a comma in the line:
[string[]]$InterfaceArray = "folder1", "folder2" "folder3"
Additionally, as far as I can tell, your do while loop doesn't appear to be accomplishing anything, as the only time this will ever be true is if the time 12:00:00AM exactly on the date specified. No matter what date you input in the format (MM/DD/YYYY), they will not be equal unless the case I said above.
Since you are searching multiple servers, Invoke-Command is your friend, as a foreach loop will act in series, while this will work in parallel. It will send out the search command to each server simultaneously.
I am not quite sure exactly what you are trying to do, so I did not fill in the actual search code(seen below), but the part i have left blank would be where you enter what filename/filename schema you are looking for. If you provide more clarity I can assist further if needed.
(Note: $filepath, although self explanatory, is the file paths you wish to search. You can generate them in a way similar to the one provided by Lee_Dailey. I'd recommend removing the divider lines and saving the paths generated to a String System.Array Object)
Invoke-Command -ComputerName $ProdServerArray -ScriptBlock {Get-Childitem –Path $filepath -Recurse -ErrorAction SilentlyContinue |where {<your code here>}}
