Similar to behavior on different versions of Powershell

Question

This code works well in Powershell 5+, but does not work in Powershell 4.0 and 2.0:

$DaysToDelete = 2

$targets = "profile/Default",
           "profile/Profile 1",
           "profile/Profile 2",
           "profile/Profile 3",
           "profile/Profile 4"

$special = @("chromium", "64")

$profiles = Get-ChildItem "C:\" -Directory -Force |
    Where-Object Name -In $special |
    Select-Object -ExpandProperty FullName

$chromeDir = "C:\Users\*\AppData\Local\Google\Chrome\User Data\Default"
$chromeSetDir = "C:\Users\*\Local Settings\Application Data\Google\Chrome\User Data\Default"

$Items = @("*Archived History*",
            "*Cache*",
            "*Cookies*",
            "*History*",
            "*Top Sites*",
            "*Visited Links*",
            "*Web Data*")

$profiles | ForEach-Object {
    foreach($target in $targets) {
        $profile = Join-Path $_ $target

        $items | ForEach-Object {
        $item = $_ 
        Get-ChildItem $profile, $chromeDir, $chromeSetDir -Recurse -Force -ErrorAction SilentlyContinue |
            Where-Object { ($_.CreationTime -lt $(Get-Date).AddDays(-$DaysToDelete))  -and $_.Directory -like $item} | ForEach-Object { 
            $path = Join-Path $_.DirectoryName $_
            Remove-Item $path -force -Verbose -recurse -ErrorAction SilentlyContinue }
         }

    }
}

I found that a fragment that breaks the execution,

-and $_.Directory -like $item

It works great on PS 5+ (Windows 10), but doesn't find anything like PS 4 (Windows 7). The Chrome version and its directory hierarchy are the same on both machines: 59.0.3071.115 (Official Build) (64-bit).

Running script on Win10 with spec support

powershell.exe -Version 4.0

Gave nothing, everything is fine. I'm not so fluent with the Powershell version, so gurus are welcome to offer any suggestions. How to make a script version independent ?

UPDATE: Here is the complete code, but it does not give anything. I checked all the places and precisely localized this problem line above.

: , like , like $_.CreationTime :

$_.CreationTime -lt $(Get-Date).AddDays(-$DaysToDelete) -and $_.Directory -like $item

Answer 1

; , , .

. PowerShell.

$_.Directory -like $item

• Get-ChildItem , System.IO.FileInfo class.

  • Directory FileInfo, .
  • Directory DirectoryInfo.

• Get-ChildItem /, System.IO.DirectoryInfo class.

  • DirectoryInfo Directory.
  • Parent, System.IO.DirectoryInfo

• . .
  : True Windows 8.1 v5.1.14409.1005; , .
  False Windows 10 PS v5.1.143993.1480; , 2016 . , Name/FullName...

Get-ChildItem -File      | Where {$_.Directory      -like "*test*"}   # not ok: comparing object to string.
Get-ChildItem -Directory | Where {$_.Directory.Name -like "*test*"}   # not ok: DirectoryInfo object does not have Directory property

Get-ChildItem -File      | Where {$_.Directory.Name -like "*test*"}   # ok
Get-ChildItem -Directory | Where {$_.Parent.Name    -like "*test*"}   # ok

Answer 2

script ?

- , , 2.0.

- PowerShell .

script Test-Path -Path "$var" .

, : PowerShell .

( like):

$newer_file_exist += Get-ChildItem -Path $profile -Recurse -Force -ErrorAction SilentlyContinue | Where-Object {$_.PSIsContainer -eq $FALSE} | where {($_.CreationTime).ToString('yyyy-MM-dd') -lt (get-date).adddays(-$DaysToDelete).ToString('yyyy-MM-dd')};

, , -$DaysToDelete. {$_.PSIsContainer -eq $FALSE}. `{$ _. PSIsContainer -eq $TRUE}.

# get all files to be deleted
ForEach ($dir in $profiles_with_path) {
    # to check
    $test_current_pathPath = Test-Path -Path $dir
    If ($test_current_pathPath) {
        #write-host 'Currently writing for these months:'$($time.Name);
        $files_to_delete += Get-ChildItem -Path $dir -recurse -Force | Where-Object {$_.PSIsContainer -eq $FALSE} | % { $_.FullName }
    }
}

:

  If ($files_to_delete) {
            ForEach ($file in $files_to_delete) { 
                #Remove-Item $file -Recurse -Force -ErrorAction SilentlyContinue
                Remove-Item $file -Force -ErrorAction SilentlyContinue
                If ($? -eq $true) {
                    $files_deleted ++;
                    #Write-Verbose -Verbose "$File deleted successfully!"
                }
            }

ForEach ($dir in $profiles_with_path) { #
    Remove-Item $dir -Recurse -Force -ErrorAction SilentlyContinue
    If ($? -eq $true) {
        $directories_deleted ++;
        #Write-Verbose -Verbose "$File deleted successfully!"
    }
}
