I wrote the script below to batch rename files with powershell. It is intended to remove dots (.) and every (-) that is followed by a number from the filenames. Example: text.10-1 becomes text101. However, I feel like there must be a way to do this in a line of code.
Also, I wanted it to also enter a subdirectory and do it, how do I write it?
Get-ChildItem | ForEach{ $_ | Rename-Item -NewName "$($_.BaseName.Replace(".",'')+$_.Extension)" }
Get-ChildItem | ForEach{ $_ | Rename-Item -NewName "$($_.BaseName.Replace("-1",'1')+$_.Extension)" }
Get-ChildItem | ForEach{ $_ | Rename-Item -NewName "$($_.BaseName.Replace("-0",'0')+$_.Extension)" }
Get-ChildItem | ForEach{ $_ | Rename-Item -NewName "$($_.BaseName.Replace("-2",'2')+$_.Extension)" }
Get-ChildItem | ForEach{ $_ | Rename-Item -NewName "$($_.BaseName.Replace("-3",'3')+$_.Extension)" }
Get-ChildItem | ForEach{ $_ | Rename-Item -NewName "$($_.BaseName.Replace("-4",'4')+$_.Extension)" }
Get-ChildItem | ForEach{ $_ | Rename-Item -NewName "$($_.BaseName.Replace("-5",'5')+$_.Extension)" }
Get-ChildItem | ForEach{ $_ | Rename-Item -NewName "$($_.BaseName.Replace("-6",'6')+$_.Extension)" }
Get-ChildItem | ForEach{ $_ | Rename-Item -NewName "$($_.BaseName.Replace("-7",'7')+$_.Extension)" }
Get-ChildItem | ForEach{ $_ | Rename-Item -NewName "$($_.BaseName.Replace("-8",'8')+$_.Extension)" }
Get-ChildItem | ForEach{ $_ | Rename-Item -NewName "$($_.BaseName.Replace("-9",'9')+$_.Extension)" }
Thanks
How about this? Get-childitem in parens to avoid the "modifying the loop" problem.
echo hi | set-content -1.txt,-2.txt,-3.txt
(get-childitem) | rename-item -newname { $_.name -replace '-(\d)','$1' } -whatif
What if: Performing the operation "Rename File" on target "Item: C:\users\admin\foo\-1.txt Destination: C:\users\admin\foo\1.txt".
What if: Performing the operation "Rename File" on target "Item: C:\users\admin\foo\-2.txt Destination: C:\users\admin\foo\2.txt".
What if: Performing the operation "Rename File" on target "Item: C:\users\admin\foo\-3.txt Destination: C:\users\admin\foo\3.txt".
You can do this with a single Get-ChildItem call:
(Get-ChildItem -Path 'D:\Test' -File -Recurse) | Where-Object { $_.BaseName -match '[-.]' } |
Rename-Item -NewName {'{0}{1}' -f ($_.BaseName -replace '[-.](\d)', '$1'), $_.Extension} -WhatIf
Note: I have added switch -WhatIf for safety so you can first see what would happen in the console. When you are satisfied with that, remove the -WhatIf switch and run again to actually start renaming the files.
switch -Recurse lets Get-ChildItem also find files in subfolders

Example "rename multiple files" gives us this:
Get-ChildItem *.txt | Rename-Item -NewName { $_.Name -replace '.txt','.log' }
But I need something like this:
Get-ChildItem *.txt | Rename-Item -NewName { $_.Name -replace '.txt','someArray[$i]' }
How can I do that ?
Simple. Take the quotes off and add a $:
EDIT: Ok, here's my guess. I don't know what $textfile is, or what result you want exactly. [^.jpg] just means any character except those 4.
get-childitem *.jpg |
Foreach {$i=0} {Rename-Item $_ -NewName ($_.name -replace 'jpg', $textfile[$i++]) -whatif}
I have a directory c:\test with files 0001 test.pdf, 0002ssssit.pdf, 0003llllllllllll.pdf
My goal is to use PS to use a a loop to go through the directory and rename the files to:
0001.pdf
0002.pdf
0003.pdf
I keep getting path errors
$List = get-childitem "C:\test"
$List |Format-Wide -Column 1 -property name
ForEach($File In $List)
{
$First4 = $File.name.substring(0,4)
Rename-Item -newname $First4".pdf"
}
You need to pass the original file path to Rename-Item, otherwise it won't know what to rename!
Either:
$file | Rename-Item -NewName "${First4}.pdf"
or
Rename-Item -LiteralPath $file.FullName -NewName "${First4}.pdf"
inside the foreach body.
You could also use a single pipeline to accomplish the same (-NewName supports pipeline binding):
$List | Rename-Item -NewName { $_.Name.Substring(0,4) + $_.Extension }
try Something like this:
Get-ChildItem "c:\temp" -file "*.pdf" |
where Name -match "^[0-9]{4}" |
rename-item -NewName {"{0}{1}" -f $_.BaseName.Substring(0, 4), $_.Extension}
Renaming pdf-files with the command
get-childitem | % { rename-item $_ "2017-$_"}
renames correctly 33 files but applying the same command to more than 33 files produces filenames looking like 2017-2017-2017...-original.name.
How can I surmount that limitation for which I have not found any explication?
Since Rename-Item accepts piped input there is no need for a ForEach,
to exclude files beginning with 2017- :
Get-ChildItem *.pdf -exclude 2017-*.pdf |
Rename-Item -Newname { $_.Name -replace '^','2017-' } -whatif
to exclude any year/4digit-number prefix :
Get-ChildItem *.pdf |
Where-Object Name -notmatch '^\d{4}-' |
Rename-Item -Newname { $_.Name -replace '^','2017-' } -whatif
If the output looks OK, remove the -whatif
Looks like your code is chasing it's tail (i.e. it's renaming things that have already been renamed). Capture the list of files into a variable, then loop through that, renaming the captured list of files:
$filesToRename = Get-ChildItem -Filter '*.pdf'
$filesToRename | ForEach-Object {
Rename-Item -Path $_.FullName -NewName "2017-$($_.FullName)"
}
If you want to exclude already renamed files:
$prefix = '2017-'
$filesToRename = Get-ChildItem -Filter '*.pdf' | Where-Object { !$_.Name.StartsWith($prefix) }
$filesToRename | ForEach-Object {
Rename-Item -Path $_.FullName -NewName "$prefix$($_.FullName)"
}
cd ("F:\Offcloud\Gossip Girl\Season 01")
Dir | Rename-Item -NewName { $_.Name -replace "%20","" }
Dir | Rename-Item -NewName { $_.Name -replace "%27","" }
Dir | Rename-Item -NewName { $_.Name -replace "a","" }
Dir | Rename-Item -NewName { $_.Name -replace "b","" }
Dir | Rename-Item -NewName { $_.Name -replace "c","" }
Dir | Rename-Item -NewName { $_.Name -replace "d","" }
Dir | Rename-Item -NewName { $_.Name -replace "e","" }
Dir | Rename-Item -NewName { $_.Name -replace "f","" }
Dir | Rename-Item -NewName { $_.Name -replace "g","" }
Etc.. basically, I want to remove everything except a small list (0123456789x). Is there any way I can do this? My current script is taking a very LONG time. Also, how can I change my script to also go through all children directories?
You can use the -Recurse parameter to search down directory levels.
$SearchFolder = "F:\Offcloud\Gossip Girl\Season 01"
Get-ChildItem -Path $SearchFolder -Recurse `
| Rename-Item -NewName {
($_.BaseName -replace "%20|%27|a|b|c|d|e|f|g","") + $_.Extension
}
Then if you use the regex's OR operator (|) in your -replace string you can replace all strings at once. The replace is done on the BaseName which is the file name without the extension. Then we simply add the extension onto the end.
use this command :
$path = "F:\Offcloud\Gossip Girl\Season 01"
dir $path -Recurse -Include * |Rename-Item -NewName { $_.Name -replace "%20|%27|a|b|c|d|e|f|g|h","" }
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
