In PowerShell, how might one return a set of paths but limit the depth of the result to 3
Here is my folder structure...
d:\testfiles\run\test01\success\build
d:\testfiles\run\test01\success\result
d:\testfiles\run\test02\fail\build
d:\testfiles\run\test02\fail\result
d:\testfiles\run\test03\exp\ready\build
d:\testfiles\run\test03\exp\ready\result
This command returns the full list of folders
Get-ChildItem -Directory d:\testfiles\run\ -recurse | Where-Object {$_.PSIsContainer -eq $true -and $_.Name -match "build|result"} | % { $_.FullName }
What I would like to get is the list of folders truncated to 3 deep, ie...
d:\testfiles\run\test01
d:\testfiles\run\test01
d:\testfiles\run\test02
d:\testfiles\run\test02
d:\testfiles\run\test03
d:\testfiles\run\test03
So, this seems to return the folders as expected...
Get-ChildItem -directory -recurse | Where-Object {$_.Name -match "^test01$|^test02$|^test03$"} | % { $_.fullname.split('\')[0..3] + '' -join '"\"' -replace ':"\\', ':\' -replace '\\"$', ''}
But this throws an error...
Get-ChildItem -directory -recurse | Where-Object {$_.Name -match "^test01$|^test02$|^test03$"} | Move-Item -Destination { $_.fullname.split('\')[0..3] + '' -join '"\"' -replace ':"\\', ':\' -replace '\\"$', ''}
The error I get...
Move-Item : Illegal characters in path.

I am trying to recursively search for files on a windows 7 machine + network drives attached to it while excluding certain folders i.e. C:\windows & all recursive folders in this such as system32.
I know this question has been asked before but following the answers has not helped and I am still left with a blank variable.
Here are the combinations I have tried:
$AllDrives = Get-PSDrive
$files=#("*.xml",*.txt)
foreach ($Drive in $AllDrives) {
if ($Drive.Provider.Name -eq "FileSystem") {
$filenames = Get-ChildItem -recurse $drive.root -include ($files) -File | Where-Object {$_.PSParentPath -notlike "*Windows*" -and $_.PSParentPath -notlike "*Microsoft*"
}
}
I have also tried these combinations:
$filenames = Get-ChildItem -recurse $drive.root -include ($files) -File | Where-Object {$_.PSParentPath -notmatch "Program Files|Users|Windows"}
$exclude_pattern = $drive.root + "Windows"
$filenames = Get-ChildItem -Force -Recurse -path $drive.root -Include $files -Attributes !Directory+!System -ErrorAction "SilentlyContinue" | Where-Object { $_.PSIsContainer -eq $false } | Where-Object { $_.FullName -notmatch $exclude_pattern }
Unfortunately, after an amount of time has elapsed, when I type $filename into the terminal nothing has been assigned to it.
I'm trying to delete some old files in an archive folder and my script works fine until it gets to the last section where it removes the empty folders (testing using -whatif initially). I get the following error:
Remove-Item : Cannot bind argument to parameter 'Path' because it is null.
At C:\ArchiveDelete.ps1:13 char:39
+ $dirs | Foreach-Object { Remove-Item <<<< $_.fullname -whatif }
+ CategoryInfo : InvalidData: (:) [Remove-Item], ParameterBindingValidationException
+ FullyQualifiedErrorId : ParameterArgumentValidationErrorNullNotAllowed,Microsoft.PowerShell.Commands.RemoveItemCommand
Tried to find a suitable answer on here but can't find a solution (I know I may be using an older version of Powershell)
#Days older than
$HowOld = -900
#Path to the root folder
$Path = "C:\SharedWorkspace\ArchiveDSAgile"
#Deletion files task
get-childitem $Path -recurse | where {$_.lastwritetime -lt (get-date).adddays($HowOld) -and -not $_.psiscontainer} |% {remove-item $_.fullname -force -whatif}
#Deletion empty folders task
do {
$dirs = gci $Path -recurse | Where { (gci $_.fullName -Force).count -eq 0 -and $_.PSIsContainer } | select -expandproperty FullName
$dirs | Foreach-Object { Remove-Item $_ -whatif }
} while ($dirs.count -gt 0)
None of your loops are necessary.
You can feed the output of Where-Object right into Remove-Item
$AgeCap = (Get-Date).AddDays(-900)
$Path = "C:\SharedWorkspace\ArchiveDSAgile"
Get-ChildItem $Path -Recurse -File | Where-Object LastWriteTime -lt $AgeCap | Remove-Item -WhatIf
The -File parameter for Get-ChildItem available in PowerShell 3.0 (I believe) and higher. The Workaround for PowerShell 2.0 would be checking against $_.PSIsContainer in Where-Object, as you did in your sample code.
Finally got it working:
#Days older than
$HowOld = -900
#Path to the root folder
$Path = "C:\SharedWorkspace\ArchiveDSAgile"
#Deletion files task
get-childitem $Path -recurse | where {$_.lastwritetime -lt (get-date).adddays($HowOld) -and -not $_.psiscontainer} |% {remove-item $_.fullname -force -whatif}
#Deletion empty folders task
Get-ChildItem $Path -Recurse | Where-Object {$_.lastwritetime -lt (get-date).adddays($HowOld) -and -not !$_.psiscontainer} | Remove-Item -recurse -WhatIf
Thanks for your help
My code below moves databases from one location to another location:
$filters = Get-Content "c:\customerName.txt"
$source = "\\Server1\Databases"
$destination = "\\Server2\Databases"
foreach($filter in $filters)
{
Get-Childitem $source -include *.* -Recurse`
| ? {!$_.PsIsContainer -and $_.fullname -match $filter} `
| % {
Move-Item $_.FullName -Destination $destination"\$filter"
}
}
The code works absolutely fine, but I need to change it so that it doesnt move files from a specific folder i.e. \\Server1\Databases\AMG
So am trying to edit the above code as following:
foreach($filter in $filters)
{
Get-Childitem $source -include *.* -Recurse | where {$_.source -notlike *"\\Server1\Databases\AMG"*} `
| ? {!$_.PsIsContainer -and $_.fullname -match $filter} `
| % {
Move-Item $_.FullName -Destination $destination"\$filter"
}
}
But if I run the code, it moves everything including the stuff from \\Server1\Databases\AMG
How can I fix this code to work as it is supposed to? Any ideas?
You need to change:
Get-Childitem $source -include *.* -Recurse | where {$_.source -notlike *"\\Server1\Databases\AMG"*}
To:
Get-Childitem $source -include *.* -Recurse | where {$_.fullname -notlike "*\\Server1\Databases\AMG*"}
There is no .source property returned by Get-Childitem. Instead you could use .fullname which is the full path for each file or folder.
You should put the * wildcard characters inside the quote marks.
I am trying to recursively remove certain characters from files and folders using a PowerShell script. Below is the script that I have found, but it will only remove underscores from files, not folders. There are a few characters which will need to be removed, but I am fine with having a script for each character if need be. It does recursively change files in the folders, but no folders are 'fixed'.
Current PowerShell script:
'dir -Recurse | where {-not $_.PsIscontainer -AND $_.name -match "_"} | foreach {
$New = $_.name.Replace("_","")
Rename-Item -path $_.Fullname -newname $New -passthru
}'
As pointed out in the comments the core of your issue is that you are excluding folders with the -Not $_.PsIscontainer component of your Where block.
dir -recurse | where {$_.name -match "_"} | ...
The second issue that you are having is most likely that since you are changing folder names the children you had previously inventoried with dir/Get-ChildItem would then have incorrect paths. One way to address this would be to process files first then folders.
$filesandfolders = Get-ChildItem -recurse | Where-Object {$_.name -match "_"}
$filesandfolders | Where-Object {!$_.PsIscontainer} | foreach {
$New=$_.name.Replace("_","")
Rename-Item -path $_.Fullname -newname $New -passthru -WhatIf
}
$filesandfolders | Where-Object {$_.PsIscontainer} | foreach {
$New=$_.name.Replace("_","")
Rename-Item -path $_.Fullname -newname $New -passthru -WhatIf
}
By no means the prettiest solution but it would work. It processes all the files first, then the folders. Remove the -Whatifs when you are sure it would do what you expect
Other characters
You had mentioned there were other characters that you were looking to remove. That wouldn't be a tall order. You could be using regex for this so lets try that.
$characters = "._"
$regex = "[$([regex]::Escape($characters))]"
$filesandfolders = Get-ChildItem -recurse | Where-Object {$_.name -match $regex}
$filesandfolders | Where-Object {!$_.PsIscontainer} | foreach {
$New=$_.name -Replace $regex
Rename-Item -path $_.Fullname -newname $New -passthru -WhatIf
}
$filesandfolders | Where-Object {$_.PsIscontainer} | foreach {
$New=$_.name -Replace $regex
Rename-Item -path $_.Fullname -newname $New -passthru -WhatIf
}
That would remove all of the periods and underscores from those files and folders.
Not tested but you might even be able to get it down to these few lines
$characters = "._"
$regex = "[$([regex]::Escape($characters))]"
$filesandfolders = Get-ChildItem -recurse | Where-Object {$_.name -match $regex}
$filesandfolders | Where-Object {!$_.PsIscontainer} | Rename-Item -NewName ($_.name -Replace $regex) -PassThru -WhatIf
$filesandfolders | Where-Object {$_.PsIscontainer} | Rename-Item -NewName ($_.name -Replace $regex) -PassThru -WhatIf
I am working with a script to clear old files off our file server. We are using this line in the script to find all files older than a certain date:
$oldFiles = Get-ChildItem $oldPath -Recurse | Where-Object { $_.lastwritetime -le $oldDate }
My question is, how do I ignore a certain directory in the $oldPath? For instance, if we had the following:
root
dir1
dir 2
subdir 1
subdir 2
dir 3
subdir 1
dir 4
And we want to ignore dir 2 and all subdirectories when building the list
Final working script:
$oldPath = "\\server\share"
$newDrive = "I:"
$oldDate = Get-Date -Date 1/1/2012
$oldFiles = Get-ChildItem $oldPath -Recurse -File | Where-Object {($_.PSParentPath -notmatch '\\Ignore Directory') -and $_.lastwritetime -le $oldDate }
$oldDirs = Get-ChildItem $oldPath -Recurse | Where-Object {$_.PSIsContainer -and ($_.PSParentPath -notmatch '\\Ignore Directory')} | select-object FullName
$oldDirs = $oldDirs | select -Unique
foreach ($oldDir in $oldDirs) {
$strdir = $newDrive + "\" + ($oldDir | Split-Path -NoQualifier | Out-String).trim().trim("\")
if (!(Test-Path $strdir)) {
Write-Host "$strdir does not exist. Creating directory..."
mkdir $strdir | Out-Null
} # end if
} # end foreach
foreach ($file in $oldFiles) {
$strfile = $newDrive + "\" + ($file.FullName | Split-Path -NoQualifier | Out-String).trim().trim("\")
Write-Host "Moving $file.FullName to $strfile..."
Move-Item $file.FullName -Destination $strfile -Force -WhatIf
} # end foreach
$oldfiles | select pspath | Split-Path -NoQualifier | Out-File "\\nelson\network share\ArchivedFiles.txt"
Modify your Where-Object condition to:
... | Where-Object {($_.PSParentPath -notmatch '\\dir 2') -and ($_.lastWriteTime -le $oldDate)}
Also, you probably want to filter out directory items as well so that $oldFiles contains only files e.g.:
$oldFiles = Get-ChildItem $oldPath -Recurse | Where {!$_.PSIsContainer -and ($_.PSParentPath -notmatch '\\dir 2') -and ($_.lastWriteTime -le $oldDate)}
If you're on PowerShell v3 you can use a new parameter on Get-ChildItem to simplify this to:
$oldFiles = Get-ChildItem $oldPath -Recurse -File | Where {($_.PSParentPath -notmatch '\\dir 2') -and ($_.lastWriteTime -le $oldDate)}
Something like this should work:
$exclude = Join-Path $oldPath 'dir 2'
$oldFiles = Get-ChildItem $oldPath -Recurse | ? {
-not $_.PSIsContainer -and
$_.FullName -notlike "$exclude\*" -and
$_.LastWriteTime -le $oldDate
}
Try $oldFiles = Get-ChildItem $oldPath -Recurse -Exclude "dir 2" | Where-Object { $_.lastwritetime -le $oldDate}
