I have the following in powershell to rename
$version = "2.1.1.1"
But i want to make a copy or rename in the same directory as
myprogram_2.1.1.1.exe
The below doesnt work
Rename-Item -Path "C:\myprogram.exe" -NewName "myprogram.exe" + $version
Any help with this ?
Try this:
$version = "2.1.1.1"
$NewName = (Get-Item "C:\myprogram.exe").Basename + "_" + $version + (Get-Item "C:\myprogram.exe").Extension
Rename-Item -Path "C:\myprogram.exe" -NewName "$NewName"
Try this:
Rename-Item -Path "c:\myprogram.exe" -NewName "myprogram${version}.exe"
When including a variable in a double-quoted string without trailing spaces, you can use ${variable} to enclose it.
You can simply do this:
Rename-Item -Path "C:\myprogram.exe" -NewName "myprogram_$version.exe"
Or:
$version = '2.1.1.1'
dir myprogram.exe | rename-item -newname { $_.BaseName + $version + $_.Extension } -whatif
What if: Performing the operation "Rename File" on target "Item:
C:\Users\js\myprogram.exe Destination:
C:\Users\js\myprogram2.1.1.1.exe".

I'm trying to rename about 500 files in a single directory. Each file is .docx format similar to the below.
Apartment_7-9_01_92.docx
Apartment_7-9_02_192.docx
etc.
I want to remove the last two/three digits before the '.', including the '_' so that I end up with
Apartment_7-9_01.docx
Apartment_7-9_02.docx
Having never really used Powershell, the research I've done so far leads me to something like the below:
Get-ChildItem -File | ForEach-Object { $_ | Rename-Item -NewName -Replace $_.Name.SubString(0, $_.lastIndexOf('_')),".docx"}
I would have thought this would take everything, including and after the last '_' and replace it with '.docx', but it's telling me the lastIndexOf method doesn't exist in this case.
Thanks
I fixed your code, but I don't think it does what you want. $_ is a fileinfo object, and $_.name is a string, and .lastindexof() is a string method. I think you want to replace a substring location after the last "_", not before it.
Get-ChildItem -File | ForEach-Object { $_ | Rename-Item -NewName (
$_.name -Replace $_.Name.SubString(0, $_.Name.lastIndexOf('_')),".docx") -whatif}
What if: Performing the operation "Rename File" on target "Item:
/Users/js/Apartment_7-9_01_92.docx Destination: /Users/js/.docx_92.docx".
What if: Performing the operation "Rename File" on target "Item:
/Users/js/Apartment_7-9_02_192.docx Destination: /Users/js/.docx_192.docx".
This seems to work, and is close to what you were trying. Just specify where the substring starts.
Get-ChildItem -File | ForEach-Object { $_ | Rename-Item -NewName (
$_.name -Replace $_.Name.SubString($_.Name.lastIndexOf('_')),".docx") -whatif}
What if: Performing the operation "Rename File" on target "Item:
/Users/js/Apartment_7-9_01_92.docx Destination:
/Users/js/Apartment_7-9_01.docx".
What if: Performing the operation "Rename File" on target "Item:
/Users/js/Apartment_7-9_02_192.docx Destination:
/Users/js/Apartment_7-9_02.docx".
There's a way to pipe directly to rename-item too, like in the docs:
Get-ChildItem -File | Rename-Item -NewName {
$_.name -Replace $_.Name.SubString($_.Name.lastIndexOf('_')),".docx"} -whatif
You could first split the BaseName on "_", then take every item except the last and rejoin back on "_". An easy way to do that is with $array[0..($array.Length - 2)]. You could also just do $array[0..2] to take the first 3 items. You can then add the Extension at the end. From here you can simply rename the FullName with Rename-Item.
$Path = "PATH/TO/FILES"
Get-ChildItem -Path $Path -File | ForEach-Object {
$items = $_.BaseName -split "_"
$newFileName = ($items[0..($items.Length - 2)] -join "_") + $_.Extension
Rename-Item -Path $_.FullName -NewName $newFileName
}
I am trying to rename a whole lot of files all located in one folder but in different subfolders. The files should be renamed so that their name consists of the foldername + the original file name. I am wondering if you could add a conditional statements so that the file name doesn't change if the file name already contains the folder name. The code below performs the function of renaming the files but doesn't contain the if statement.
dir -recurse | Rename-Item -NewName {$_.Directory.Name + " - " + $_.Name}
The code below is an example on how I imagine the code would look:
dir -recurse | if($_.Name -contains $_.Directory.Name) {Rename-Item -NewName {$_.Directory.Name + " - " + $_.Name}}
This should do it:
$rootFolder = 'D:\test'
Get-ChildItem -Path $rootFolder -File -Recurse | ForEach-Object {
$folder = $_.Directory.Name
if (!($_.Name.StartsWith($folder))) { $_ | Rename-Item -NewName ('{0} - {1}' -f $folder, $_.Name) }
}
Theo's answer works well, but there's an alternative that is both conceptually simpler and performs noticeably better:
You can take advantage of the fact that passing an unchanged file name to -NewName is a quiet no-op, so you can place all your logic in the -NewName script block:
Get-ChildItem -File -Recurse |
Rename-Item -NewName {
if ($_.Name -like ($_.Directory.Name + ' - *') { # already renamed
$_.Name # no change
}
else { # rename
$_.Directory.Name ' - ' + $_.Name
}
} -WhatIf
-WhatIf previews the renaming operation; remove it to perform actual renaming.
Rather than using ForEach-Object call with a nested Rename-Item call in its script block - which means that Rename-Item is called once for each input file - this solution uses a single pipeline with a single Rename-Item invocation, where the new name (if changed) is determined via a delay-bind script block - see this answer for details.
I was trying it in a way close to the way the question was asked. I wish I didn't have to add another foreach.
dir -recurse -file | & {
foreach ($i in $input) {
if(-not ($i.Name.contains($i.Directory.Name))) {
Rename-Item $i.fullname -NewName ($i.Directory.Name + ' - ' + $i.Name) -whatif
}
}
}
Or like this
dir -recurse -file | % {
if(-not ($_.Name.contains($_.Directory.Name))) {
Rename-Item $_.fullname -NewName ($_.Directory.Name + ' - ' + $_.Name) -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}
Currently I'am facing an issue in renaming file names with powershell. I'am actually able to rename files in a particular folder, however if the structure is different the command fails.
Example files:
test file - 1234 - copy.docx
test file - 1234.pdf
I was running the following command:
Get-ChildItem <location> -file | foreach {
Rename-Item -Path $_.FullName -NewName ($_.Name.Split("-")[0] + $_.Extension) }
I want to keep the filename before the last "-". But if I run my command, I always get file name before the first "-".
Any advice for a better approach?
Most straightforward approach:
Get-ChildItem <location> -File | Rename-Item -NewName {
$index = $_.BaseName.LastIndexOf("-")
if ($index -ge 0) {
$_.BaseName.Substring(0, $index).Trim() + $_.Extension
}
else { $_.Name }
}
Regex replace:
Get-ChildItem <location> -File |
Rename-Item -NewName {($_.BaseName -replace '(.*)-.*', '$1').Trim() + $_.Extension}
You could use RegEx to achieve the desired output:
Rename-Item -Path $_.FullName -NewName (($_.Name -replace '(.*)-.*?$','$1') + $_.Extension) }
(.*)-.*?$ selects all chars (greedy) until the last - before the end of the line.
We had a syncing issue that affected thousands of files.
A backup of the correct files was created in each folder by the sync tool. the backup has " -LocalPCName" added before the dot before the extension.
I am really a beginner in powershell.
I am trying to write a powershell script to go trough every folder and check if a file backup was create d for each file.
If a backup was created, I want to rename the file to add " -Wrongversion" and remove the " -LocalPCName" from the correct file.
This will basically recover the file to the correct version and make a copy of the wrong version.
I wrote this code but i am blocked at trying to match using -replace
Get-ChildItem *.* |
ForEach-Object {
If ($_.name -match "\s-LocalPCName")
{Get-ChildItem $_.Name -replace "\s-LocalPCName",""
}
}
Thank you for your help!
here is a newer version of my code but i get errors and i am concerned of using recurse, am i missing anything when this will go to subfolders? In this code, the LocalPCName is Didi2015
Get-ChildItem *.* -recurse|
ForEach-Object {
If ($_.name -match "\s-Didi2015")
{
$OldName = $_.Name -replace "\s-Didi2015",""
$dir=$_.DirectoryName
$ext = $_.Extension
$file = $OldName.Substring(0, $OldName.LastIndexOf('.'))
Write-Output $dir
Write-Output $ext
Write-Output $file
$Newname = $file + " -Wrongversion" + $ext
Write-Output $Newname
Rename-Item -Path $OldName -NewName $Newname -WhatIf
Rename-Item -Path $_ -NewName $OldName -WhatIf
}
}
Here is my final code. it works.
dir *-Didi2015*.* -Recurse|
ForEach-Object {
If ($_.name -match "-Didi2015")
{
$OldName = $_ -replace "-Didi2015",""
$dir=$_.DirectoryName
$ext = $_.Extension
$file = $OldName.Substring(0, $OldName.LastIndexOf('.'))
# Write-Output $dir
# Write-Output $ext
# Write-Output $file
# Write-Output $OldName
# Write-Output $Newname
# Write-Output $_.Name
$Newname = $file + "-Wrongversion" + $ext
Rename-Item -Path $OldName -NewName $Newname -WhatIf
Rename-Item -Path $OldName -NewName $Newname -Force
Rename-Item -Path $_ -NewName $OldName -WhatIf
Rename-Item -Path $_ -NewName $OldName -Force
}
}
