I want to replace all space characters into "_" in names of all subfolders and files.
Unfortunately when I type:
Get-ChildItem -recurse -name | ForEach-Object { Rename-Item $_ $_.replace(" ","_") }
Error message:
Rename-Item : Source and destination path must be different. At line:1
char:60
+ Get-ChildItem -recurse -name | ForEach-Object { Rename-Item <<<< $_ $.replace(" ","") }
+ CategoryInfo : WriteError: (PATH_HERE) [Rename-Item], IOException
+ FullyQualifiedErrorId : RenameItemIOError,Microsoft.PowerShell.Commands.RenameItemCommand
How I should improve this short code?
Don't use the Name switch, it outputs only the names of the objects, not their full path. Try this:
Get-ChildItem -Recurse | `
Where-Object {$_.Name -match ' '} | `
Rename-Item -NewName { $_.Name -replace ' ','_' }
The issue here is that if there is no space in the file name the name does not change. This is not supported by Rename-Item. You should use Move-Item instead:
Get-ChildItem -recurse -name | ForEach-Object { Move-Item $_ $_.replace(" ", "_") }
Additionally, in your answer you missed the underscore in $_.replace(...) plus you where replacing spaces with an empty string. Included this in my answer.
Adding a filter worked for me:
Get-ChildItem C:\path-to-directory -Recurse -Filter *foo* | Rename-Item -NewName { $_.name -replace 'foo', 'bar'} -verbose

I am a PowerShell newbie. I have the following command to rename all subfolders:
Get-ChildItem -r | foreach{Rename-Item $_.FullName ($_.Name -replace "2021", "2021 renamed")}
This command works correctly, but also returns an error message:
Rename-Item : Source and destination path must be different.
At line:1 char:28
+ ... e | foreach{Rename-Item $_.FullName ($_.Name -replace "2021", "2021 r ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : WriteError: (C:\Users\abc\...def\ghi\2025:String) [Rename-Item], IOException
+ FullyQualifiedErrorId : RenameItemIOError,Microsoft.PowerShell.Commands.RenameItemCommand
Where ...def\ghi\2025 is the last subfolder.
Could someone please advise me what the error in my command is?
If you want to only rename subfolders, then you should add -Directory parameter. Also, you can pipe directly to Rename-Item, no foreach loop is required. The error message is shown for those items that you don't actually change (don't have 2021 in the name for example so the new name is the same as the old.) You could just set erroraction to silently continue.
Get-ChildItem -Directory -Recurse |
Rename-Item -NewName {$_.Name -replace "2021", "2021 renamed"} -ErrorAction SilentlyContinue
Or if you'd prefer you can stick with the loop and only attempt to rename those that actually have the matching criteria
Get-ChildItem -r | ForEach-Object{
if($_.name -match '2021')
{
Rename-Item $_.FullName ($_.Name -replace "2021", "2021 renamed")
}
}
I'm basically trying to trim() any filenames that have a leading or trailing space at the end of the name. This is the code I've got so far
$foldersToCheck = "$env:userprofile\documents", "$env:userprofile\pictures", "$env:userprofile\desktop"
foreach ($folder in $foldersToCheck) {
get-childitem -path $folder -recurse | foreach-object {
if ($_.name.startswith(" ") -or $_.name.endswith(" ")) {
$newName = $_.name.trim()
rename-item -path $_ -newName $newname
}
}
}
If I create a test file (c:\users\someusername\desktop\ test.txt), then I receive this error
rename-item : Cannot rename because item at ' test.txt' does not exist.
At line:6 char:13
+ rename-item -path $_ -newName $newname
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (:) [Rename-Item], PSInvalidOperationException
+ FullyQualifiedErrorId : InvalidOperation,Microsoft.PowerShell.Commands.RenameItemCommand
So, it looks like it found the file that needs to be renamed, but then says it doesnt exist.
The problem here is that PowerShell resolves $_ to just the file name when attempting to convert it to a string it can bind to -Path.
Explicitly pass the full path of the file and it'll work:
Rename-Item -Path $_.FullName -NewName $newname
Alternatively, pipe the $_ file object to Rename-Item and PowerShell will automatically figure out that it needs to bind $_.FullName to Rename-Item's -LiteralPath parameter:
$_ |Rename-Item -NewName $newname
You can also turn the whole loop into a single pipeline, and then take advantage of a pipeline-bound expression against -NewName:
$foldersToCheck |Get-ChildItem -Recurse |Rename-Item -NewName { $_.Name.Trim() }
If the existing Name and the -NewName values are the same, Rename-Item will just leave the files alone anyway :)
So, i need to save a string that was replaced on files.
I'm doing something wrong, but i`m not be able to figure it out, what!
My code:
Get-ChildItem -Path C:\Users\user\Documents -Recurse -Include "*.txt" -File | Select-String -Pattern \b192\.168\.10\.2\b , \b192\.168\.10\.11\b -AllMatches -List | Foreach-Object { $_ -replace '\b192\.168\.10\.2\b', "DEV" -and $_ -replace '\b192\.168\.10\.11\b', "QUAL" | Set-Content $_}
And gives-me the following error:
Set-Content : Could not open the alternate data stream '1:192.168.10.11' of the file 'C:\Users\user\Documents\result.txt'.
At line:1 char:323

FullyQualifiedErrorId : GetContentWriterFileNotFoundError,Microsoft.PowerShell.Commands.SetContentCommand
Thanks for any Help!
Inside the ForEach-Object block, $_ will refer to the current match result as returned by Select-String - to get the file path, reference the Path property:
... | ForEach-Object { ... |Set-Content -LiteralPath $_.Path}
The -and operator is used inside if tests like if(this -and that).
You should change the double replace actions from
$_ -replace '\b192\.168\.10\.2\b', "DEV" -and $_ -replace '\b192\.168\.10\.11\b', "QUAL"
into
$_ -replace '\b192\.168\.10\.2\b', "DEV" -replace '\b192\.168\.10\.11\b', "QUAL"
Also, if I understand the question properly, you want to find all string replacements in the file, and to get all, you need to remove the -List switch from Select-String.
Next, as Mathias explains in his answer, you need to use the Path property from the current match to get the file FullName.
However, if you pipe this through to Set-Content straight away, you will get an exception because the file then is in use and you cannot write to the same file.
Below creates a new file in the same path, with _replacements appended to the filename
# use '-Include' instead of '-Filter' if you need more file extensions to filter on
Get-ChildItem -Path 'C:\Users\user\Documents' -Recurse -Filter "*.txt" -File |
Select-String -Pattern '\b192\.168\.10\.2\b', '\b192\.168\.10\.11\b' -AllMatches |
Foreach-Object {
$file = '{0}_replacements{1}' -f [System.IO.Path]::GetFileNameWithoutExtension($_.Path),
[System.IO.Path]::GetExtension($_.Path)
$target = Join-Path -Path ([System.IO.Path]::GetDirectoryName($_.Path)) -ChildPath $file
$_ -replace '\b192\.168\.10\.2\b', "DEV" -replace '\b192\.168\.10\.11\b', "QUAL" |
Add-Content -Path $target
}
This results in a file called 'C:\Users\user\Documents\test_replacements.txt'
C:\Users\user\Documents\test.txt:4:DEV
C:\Users\user\Documents\test.txt:7:QUAL
The original file 'C:\Users\user\Documents\test.txt' will not be altered.
I'm having problems after a folder is copied to a different location, I need to rename the folders in the directory to remove ".deploy" from the end, but I get the following error below. I have Googled around for PowerShell admin permissions, but cannot seem to find a 'catch-all' for my scenario.
Get-Content : Access to the path 'C:\OldUserBackup\a.deploy' is denied.
At C:\PSScripts\DesktopSwap\TestMergeDir.ps1:28 char:14
+ (Get-Content $file.PSPath) |
+ ~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : PermissionDenied: (C:\OldUserBackup\a.deploy:String) [Get-Content], UnauthorizedAccessException
+ FullyQualifiedErrorId : GetContentReaderUnauthorizedAccessError,Microsoft.PowerShell.Commands.GetContentCommand
Here is what I have:
$UserName = [Environment]::UserName
$CurrUser = [Environment]::UserName + '.deploy'
$OldUserDir = 'C:\OldUserBackup'
$CurrDate = Get-Date -format G
$PathExist = Test-Path $OldUserDir
if ($PathExist -eq $true) {
#Copy Desktop, Downloads, Favorites, Documents, Music, Pictures, Videos
Copy-Item -Path $OldUserDir -Destination C:\Users\$UserName\Desktop\CopyTest -Recurse -Force
$configFiles = Get-ChildItem $OldUserDir *.deploy -rec
foreach ($file in $configFiles) {
(Get-Content $file.PSPath) |
Foreach-Object { $_ -replace ".deploy", "" } |
Set-Content $file.PSPath
}
}
You should use the -Directory switch on the Get-ChildItem cmdlet to only get directories. Then use the Rename-Item cmdlet to rename the folders. I use the -replace function with a simple regex to get the new folder name:
$deployFolders = Get-ChildItem $OldUserDir *.deploy -rec -Directory
$deployFolders | Foreach {
$_ | Rename-Item -NewName ($_.Name -replace ('\.deploy$') )
}
You don't even have to use the Foreach-Object cmdlet (Thanks to AnsgarWiechers):
Get-ChildItem $OldUserDir *.deploy -rec -Directory |
Rename-Item -NewName { $_.Name -replace ('\.deploy$') }
Calling this powershell command and getting an error. Driving me nuts.
Prompt> get-childitem -recurse ./ *NYCSCA* | where-object { $_.Name -like
"*NYCSCA*" } | rename-item $_ -newname $_.Name.Replace(" ","_") -whatif
Here is the response:
You cannot call a method on a null-valued expression.
At line:1 char:140

If I remove the last part, I get a list of files. Any clues? I have not grocked powershell yet, obviously.
Note: I tried to post this to superuser, but the site is consistently failing now - won't let me add this exact question.
Here it is greatly simplified. I cannot even get this classic example to work.
gci *NYCSCA* | ren $_ ($_.Name).Replace("foo","bar")
Thank you #JNK, the % did it. The solution I needed is this, in case you're interested:
gci -recurse | where-object{ $_.Name -like "*NYCSCA*"} | %{rename-item $_.FullName $_.FullName.Replace("NYCSCA","SDUSD") }
I think you need foreach-object:
get-childitem -recurse ./ *NYCSCA* | where-object { $_.Name -like
"*NYCSCA*" } | % {rename-item $_ -newname $_.Name.Replace(" ","_") -whatif}
The piped array can't be renamed as a set.
Here's a simplified version to rename files only
Get-ChildItem -Filter *NYCSCA* -Recurse |
Where-Object {!$_.PSIsContainer} |
Rename-Item -NewName { $_.Name.Replace(' ','_') } -WhatIf
