PowerShell - Loop through files and rename












2















newbie here. I am trying to write a PowerShell script to:




  1. loop through all files in directory

  2. List item


  3. Get all .pdf files ONLY



    Rename them-the file names are long - over 30 chars
    -They contain 2 numbers which I need to extract
    -Example:



    Cumulative Update 11 for Microsoft Dynamics NAV 2018 (Build 25480).pdf ->
    RESULT : = 18CU11.pdf




I tried examples from bunch of sites and I can't seem to even loop successfully.
Either get an error - that path doesn't exist or that can't rename files as somehow loop gets a filepath and that I can't rename



Get-ChildItem "C:Users******DesktopPowerShell Practice" -Filter *.pdf |  #create list of files



ForEach-Object{

    $oldname = $_.FullName;

    $newname = $_.FullName.Remove(0,17); 

    #$newname = $_.FullName.Insert(0,"CU")



    Rename-Item $oldname $newname;



    $oldname;

    $newname;  #for testing

}


That's just latest attempt, but any other ways of doing it will be fine - as long as it does the job.

    How do your original filenames look exactly?

    If it says the path doesn't exist, then probably .. the path doesn't exist? You should include the actual output from your attempts!

Try this logic:



[string]$rootPathForFiles = Join-Path -Path $env:USERPROFILE -ChildPath 'DesktopPowerShell Practice'

[string]$listOfFilesToRename = Get-ChildItem -Path $rootPathForFiles -Filter '*.PDF' | Select-Object -ExpandProperty FullName

$listOfFilesToRename | ForEach-Object {

    #get the filename wihtout the directory

    [string]$newName = Split-Path -Path $_ -Leaf 

    #use regex replace to apply the new format

    $newName = $newName -replace '^Cumulative Update (d+) .*NAV 20(d+).*$', '$2CU$1.pdf' # Assumes a certain format; if the update doesn't match this expectation the original filename is maintained

    #Perform the rename

    Write-Verbose "Renaming '$_' to '$newName'" -Verbose #added the verbose switch here so you'll see the output without worrying about the verbose preference

    Rename-Item -Path $_ -NewName $newName 

}
