Issues with -exclude in powershell

Hi guys, I've been trying to get a script working that will go through all the folders and files in a location and add them to a text file then delete them all excluding a couple of folders but I haven't got a lot of experience with powershell yet and I was looking for advice.

Here's the script so far:

$targetfolder = "C:\ScriptTest\ftproot"

$date = get-date -format ddMMyyyy

Get-ChildItem $targetfolder -Exclude "C:\ScriptTest\ftproot\google", "C:\ScriptTest\ftproot\Expedia", "C:\ScriptTest\ftproot\Corpedia" | Where {!$_.PSIsContainer -and $_.LastWriteTime -lt (get-date).AddDays(-2)} | Out-File "C:\ScriptTest\ftproot\$Date.txt"

Get-ChildItem $targetfolder -Exclude "C:\ScriptTest\ftproot\google", "C:\ScriptTest\ftproot\Expedia", "C:\ScriptTest\ftproot\Corpedia" | Where {!$_.PSIsContainer -and $_.LastWriteTime -lt (get-date).AddDays(-2)} | remove-item

Open in new window


I've run everything up till the delete part but the text file is still picking up the folders I want to exclude, can anyone offer advice?

Try this.

I have not tested but I think your quotes might be your issue.

$targetfolder = "C:\ScriptTest\ftproot"

$date = get-date -format ddMMyyyy

$excluded = "C:\ScriptTest\ftproot\google, C:\ScriptTest\ftproot\Expedia, C:\ScriptTest\ftproot\Corpedia"


Get-ChildItem $targetfolder -Exclude $excluded | Where {!$_.PSIsContainer -and $_.LastWriteTime -lt (get-date).AddDays(-2)} | Out-File "C:\ScriptTest\ftproot\$Date.txt"

Get-ChildItem $targetfolder -Exclude $excluded | Where {!$_.PSIsContainer -and $_.LastWriteTime -lt (get-date).AddDays(-2)} | remove-item

That's great and works to exclude items in the folders but I've just realised I left out the -recurse parameter in the main post, I added -recurse where I thought it should go and it still excludes what is in the folders but it doesn't exclude subfolders, will I have to add each subfolder to the $excluded variable or is there another way?
Here is where I added -recurse to your code:

$targetfolder = "C:\ScriptTest\ftproot"

$date = get-date -format ddMMyyyy

$excluded = "C:\ScriptTest\ftproot\google, C:\ScriptTest\ftproot\Expedia, C:\ScriptTest\ftproot\Corpedia"


Get-ChildItem $targetfolder -Exclude $excluded -Recurse | Where {!$_.PSIsContainer -and $_.LastWriteTime -lt (get-date).AddDays(-2)} | Out-File "C:\ScriptTest\ftproot\$Date.txt"

Get-ChildItem $targetfolder -Exclude $excluded -Recurse | Where {!$_.PSIsContainer -and $_.LastWriteTime -lt (get-date).AddDays(-2)} | remove-item

Try this..
$targetfolder = "C:\ScriptTest\ftproot\"
$date = get-date -format ddMMyyyy
$Dir = GCI -Path $targetfolder -Recurse | ? {$_.PSIsContainer -and `
$_.fullname -ne 'C:\ScriptTest\ftproot\google' -and `
$_.fullname -ne 'C:\ScriptTest\ftproot\Expedia' -and `
$_.fullname -ne 'C:\ScriptTest\ftproot\Corpedia' } | Select -ExpandProperty fullname

$Dir | Get-ChildItem -Recurse | Where {!$_.PSIsContainer -and $_.LastWriteTime -lt (get-date).AddDays(-2)} | Out-File "C:\ScriptTest\ftproot\$Date.txt"

$Dir | Get-ChildItem -Recurse | Where {!$_.PSIsContainer -and $_.LastWriteTime -lt (get-date).AddDays(-2)} | remove-item -WhatIf

Open in new window


PS : I have added -WhatIf for testing, you can remove -WhatIf to delete the files..

Forgot to add Recurse for excluded folders.. Check this updated script..
$targetfolder = "C:\ScriptTest\ftproot\"
$date = get-date -format ddMMyyyy
$Dir = GCI -Path $targetfolder -Recurse | ? {$_.PSIsContainer -and `
$_.fullname -notmatch 'C:\\ScriptTest\\ftproot\\google' -and `
$_.fullname -notmatch 'C:\\ScriptTest\\ftproot\\Expedia' -and `
$_.fullname -notmatch 'C:\\ScriptTest\\ftproot\\Corpedia'} | Select -ExpandProperty fullname

If ($Dir) {
$Dir | Get-ChildItem -Recurse | Where {!$_.PSIsContainer -and $_.LastWriteTime -lt (get-date).AddDays(-2)} | Out-File "C:\ScriptTest\ftproot\$Date.txt"
$Dir | Get-ChildItem -Recurse | Where {!$_.PSIsContainer -and $_.LastWriteTime -lt (get-date).AddDays(-2)} | remove-item -WhatIf
}

$targetfolder = "C:\ScriptTest\ftproot"

$date = get-date -format ddMMyyyy

$excluded = "C:\ScriptTest\ftproot\google, C:\ScriptTest\ftproot\Expedia, C:\ScriptTest\ftproot\Corpedia"
$exlist = $excluded.split(",")


 
foreach ($excludeditem in $exlist)
{

Get-ChildItem $targetfolder -Exclude $excluded -Recurse | Where {!$_.PSIsContainer -and $_.LastWriteTime -lt (get-date).AddDays(-2) -and _.fullname -notlike "*$excludeditem*"} | Out-File "C:\ScriptTest\ftproot\$Date.txt"

Get-ChildItem $targetfolder -Exclude $excluded -Recurse | Where {!$_.PSIsContainer -and $_.LastWriteTime -lt (get-date).AddDays(-2) -and _.fullname -notlike "*$excludeditem*"} | remove-item
                                            


}

Jumped the gun with my last comment, I hadn't noticed subsun's updated response. I'm afraid it will still exclude the top level folders but not the subfolders. Thanks for the effort though, would it make more sense if I just added the subfolders to the exclude list?

Actually after having another look at the results of the text file none of the excluded files are showing up in it which is right, but the -whatif said that the subfolders would still be removed? I hope this information helps

Not sure why it is giving you that result, I can see both the commands (Line 9 and 10) are same except one pipe the output to Out-File and other to Remove-Item.. Could you please double check the script ans see if it is same as I posted in my comments?

That was my mistake sorry, rookie mistake I didn't cls before I ran the updated one and I scrolled too far. That seems to work excellently now thank you both for your help! I'll try it in the test environment now without the -whatif just to be sure but that should work thank you.
