Powershell - delete folder if exists in an other directory

I have folders in"Directory1" and zip of these folders in "Directory2" with the mention "_OK" at the end of the zip name.

Directory1 : Directory1 1B002955_SML 23_LEAP 1A version2 mars2022_2022-03-11T08h00m40s_s603575

Directory2 : Directory21B002955_SML 23_LEAP 1A version2 mars2022_2022-03-11T08h00m40s_s603575_OK

Now i want to delete the folders from the 1st directory if the corresponding zip exists in the 2nd directory. The two directory aren't on the same server.

I thought about renaming Directory2 zip by removing "_OK"

rename-item $_ $_.Name.Replace("_OK", "")

Then compare Directory1 and Directory2 with the compare-object cmdlet but I found that it's for comparing the specified properties and in my case I just want to compare names

Still new to powershell, i'm not sure the best way to proceed

Hope someone can help

Thank you

Solution

  • Use the Compare-Object cmdlet as follows, assuming that:

    as output by Get-ChildItem calls:

    Compare-Object -IncludeEqual -PassThru $filesA $filesB -Property { 
    $_.BaseName -replace '_OK$'
  } | Where-Object SideIndicator -eq == | 
        Remove-Item -Recurse -Force -WhatIf

    Note: The -WhatIf common parameter in the command above previews the operation. Remove -WhatIf once you're sure the operation will do what you want.

    • -IncludeEqual makes Compare-Object also include objects that compare the same (by default, only differing objects are reported).

    • -PassThru causes the LHS input object from a pair of matching objects to be output (by default, only the matching property value - as defined by the -Property argument(s) - is output.)

    • -Property { $_.BaseName -replace '_OK$' } uses a nameless calculated property to compare pairs of input objects by; in this case, the -replace operator is used to effectively remove string _OK, if present at the end ($), from the base file name (the file name without extension).

    • Where-Object SideIndicator -eq == limits the output to objects that compare equal, using simplified syntax.

    • Adding -Recurse to the Remove-Item ensures that no confirmation prompt is shown if the target directory is non-empty; -Force ensures that removal succeeds even if the target directory is hidden or contains hidden items.
