Powershell：使用数组和gci

Question

thanks for help in advance. I am new to powershell, so sorry for noobish questions.

Problem: I import a csv with filenames to an array. The array consists out of numbers (ie 95325866256) what are filenames. My aim is to copy all files from a remote system with the IDs from the array. Here is what I tried:

$array_chipIDs = Import-csv "C:\Data\chipID.csv" -UseCulture
$Export = "C:\Data\Export"
Write-Host -ForegroundColor Cyan "Anzahl der IDs: "$array_chipIDs.count

foreach ($i in $array_chipIDs){
Write-Host -ForegroundColor Yellow $i 

 foreach ($chipID in $array_chipIDs) {  
       Get-ChildItem -Path $pfad1 -Recurse -Include *.sdf, *.idat | select FullName | Copy-Item -Path {$_.Fullname} $export  
    if ($chipID -eq ''){
   break
   }
       }

But I miss the Point to give the gci the actual array value (the filename).

Thanks for help!

Answer 1

You are doing it wrong. You get the IDs from file and you loop through them but the files you are copying are from $pfad1 variable which is not defined anywhere by the way. You are also looping twice without a reason.

If you just want to copy files from one folder to another folder then use this example.

 $source = "c:\sourcefolder"
 $destination = "c:\destinationfolder\"
 get-childitem -Recurse $source | Where {$_.PSIsContainer -eq $False} | 
     copy-item -Destination $destination

You can define the source and destination folders to be network paths as long as you have permissions on the folders.

Now this will copy any files from source to destination. If you want to restrict particular type or extension of files then we can extend the above.

 $source = "c:\sourcefolder"
 $destination = "c:\destinationfolder\"
 $extensions = @("*.sdf","*.idat")
 foreach($e in $extensions){
     get-childitem -Recurse $source -Filter $e | Where {$_.PSIsContainer -eq $False} | 
         copy-item -Destination $destination

}

This code will then try and get only the extensions added to the array $extensions. You can add more extensions.

If you want to do it from the file like the excel then may be share a sample. The file must have the correct file name. If it does not have the full path then you need to define the actual path in a variable like source. But can't say much unless you give us an example. Hope this helps.

Answer 2

The first loop was just to check the Import of my csv. But here is now a working foreach-loop.

foreach($chipID in $array_chipIDs) {
   Get-ChildItem -Path $s_path -Recurse -Include "filetype" | Where-Object { $_.FullName -match $chipID.ChipID } | Copy-Item -Destination $export
    }
