I'm new in powershell, I have to execute the following statement recursively:
Get-ChildItem | ForEach-Object {Rename-Item $_ -NewName ("new_filename{0}.smali" -f $nr++)}
In other words I have to rename all the .smali files in the subdirectories with any other name different from the current one (keeping the .smali extension).
Get-ChildItem -Path FolderPath -Filter *.smali -Recurse | ForEach-Object{$_ | Rename-Item -NewName ($.BaseName + StringToAdd + $.Extension) -WhatIf}
Copy the above line as is... Replace the values for FolderPath and StringToAdd and give it a try. If everything looks fine then execute it by removing the -Whatif switch.
dir is an alias for Get-ChildItem which has a -Recursive parameter.
$nr = 0; Get-ChildItem -Recurse -Filter "*.smali" | Rename-Item -NewName "new_filename$($nr++).smali"
Things to note:
DIR is an alias for Get-ChildItem. Get-ChildItem is more Powershell-y
Your command only looked at the top level directory, so I added the -recurse
Your command would rename all files, not just the "*.smali", so I added the filter.

From root folder, I am trying to search all files in subdirectories with "-poster" and rename those files to only poster without changing the file extension. All these files have other text in front of the "-poster" that I want to remove, and all the files are .jpgs.
Would a command such as this work:
Get-ChildItem -filter *-poster* -recurse | ForEach {Rename-Item $_ -NewName "poster.jpg"}
I haven't tried it, as don't want to risk changing other files.
Use the -WhatIf common parameter to preview an operation without actually performing it:
Get-ChildItem -Filter *-poster* -Recurse |
Rename-Item -NewName poster.jpg -WhatIf
Note:
-WhatIf does not test actual runtime conditions.
That is, if a poster.jpg file already exists in the target directory, the Rename-Item call will fail once -WhatIf is removed.
To handle this case, you have the following options, depending on your use case:
Allow the failure, if you don't expect a preexisting file.
Ignore the failure, if a preexisting file implies that no action is needed: add -ErrorAction Ignore to the Rename-Item call.
Blindly overwrite the existing file, by adding -Force to the Rename-Item call.
Create a file with a different name, such as by appending a sequence number, using a delay-bind script block - see below.
Get-ChildItem -Filter *-poster* -Recurse |
Rename-Item -NewName {
$newBaseName = 'poster.jpg'
$newBaseName = [IO.Path]::GetFileNameWithoutExtension($newName)
$newExtension = [IO.Path]::GetExtension($newName)
$suffix = ''
if ([array] $preexisting = Get-ChildItem -File -LiteralPath $_.DirectoryName -Filter "$newBaseName*$newExtension")) {
$highestNumSoFar = [int[]] ($preexisting.BaseName -replace '^.*\D') | Sort-Object -Descending | Select-Object -First 1
$suffix = $highestNumSoFar + 1
}
$newBaseName + $suffix + $newExtension
} -WhatIf
I want a solution for the same problem, but in Windows 10.
Recursively rename .jpg files in all subdirectories
I tried with following powershell command,
Get-ChildItem -Recurse -Include *.jpg | % { Rename-Item $_ -NewName ('{0:D1}.jpg' -f $i++)}
but it renames the files in sequential order without resetting the index to 1 in every sub folder.
I think you need two separate Get-ChildItem cmdlets for this. The first will gather all subdirectories and when looping though that, the second will gather the files in each directory:
Get-ChildItem -Path 'X:\RootFolder\where\the\files\are' -Recurse -Directory | ForEach-Object {
$count = 1 # reset the counter for this subdir to 1
Get-ChildItem -Path $_.FullName -Filter '*.jpg' -File | ForEach-Object {
$_ | Rename-Item -NewName ('{0:D1}.jpg' -f $count++) -WhatIf
}
}
Remove the -WhatIf if you are satisfied with the results shown in the console.
P.S. the title says *.png, but your code deals with *.jpg. Doesn't matter, as long as you set your filter to the correct extension and adjust the new name in the code accordingly
As of my knowledge you have to do use it as a nested foreach:
Foreach ($directory in (Get-ChildItem -Directory)){
$i = 1
Get-ChildItem $directory.Fullname -Recurse -Include *.jpg | % { Rename-Item $_ -NewName ('{0:D1}.jpg' -f $i++)}
}
I tested it and it worked :)
If it worked for you, please mark it as the accepted answer.
I have a piece of software which looks for a files named "report.txt". However, the text files aren't all named report.txt and I have hundreds of sub folders to go through.
Scenario:
J:\Logs
26-09-16\log.txt
27-09-16\report270916.txt
28-09-16\report902916.txt
I want to search through all the sub folders for the files *.txt in J:\logs and rename them to report.txt.
I tried this but it complained about the path:
Get-ChildItem * |
Where-Object { !$_.PSIsContainer } |
Rename-Item -NewName { $_.name -replace '_$.txt ','report.txt' }
Get-ChildItem * will get your current path, so in instead let's use the define the path you want Get-ChildItem -Path "J:\Logs" and add recurse because we want the files in all the subfolders.
Then let's add use the include and file parameter of Get-ChildItem rather than Where-Object
Then if we pipe that to ForEach, we can use the Rename-Item on each object, where the object to rename will be $_ and the NewName will be report.txt.
Get-ChildItem -Path "J:\Logs" -include "*.txt" -file -recurse | ForEach {Rename-Item -Path $_ -NewName "report.txt"}
We can trim this down a bit in one-liner fashion with a couple aliases and rely on position rather than listing each parameter
gci "J:\Logs" -include "*.txt" -file -recurse | % {ren $_ "report.txt"}
To replace certin word in all files in all sub folders
Get-ChildItem C:\Path -Recurse -Filter *OldWord* | Rename-Item -NewName { $_.name -replace 'OldWord', 'NewWord'} -verbose
I am trying to remove blank spaces from many file names using PowerShell 3.0. Here is the code that I am working with:
$Files = Get-ChildItem -Path "C:\PowershellTests\With_Space"
Copy-Item $Files.FullName -Destination C:\PowershellTests\Without_Space
Set-Location -Path C:\PowershellTests\Without_Space
Get-ChildItem *.txt | Rename-Item -NewName { $_.Name -replace ' ','' }
For example: the With_Space directory has these files:
Cable Report 3413109.pdf
Control List 3.txt
Test Result Phase 2.doc
The Without_Space directory will need the above file name to be:
CableReport3413109.pdf
ControlList3.txt
TestResultPhase 2.doc
Currently, the script shows no error but it only copies the source files to the destination folder, but doesn't remove the spaces in file names.
Your code should work just fine, but since Get-ChildItem *.txt lists only .txt files the last statement should remove the spaces from just the text files, giving you a result like this:
Cable Report 3413109.pdf
ControlList3.txt
Test Result Phase 2.doc
This should remove spaces from the names of all files in the folder:
Get-ChildItem -File | Rename-Item -NewName { $_.Name -replace ' ','' }
Prior to PowerShell v3 use this to restrict processing to just files:
Get-ChildItem | Where-Object { -not $_.PSIsContainer } |
Rename-Item -NewName { $_.Name -replace ' ','' }
something like this could work
$source = 'C:\temp\new'
$dest = 'C:\temp\new1'
Get-ChildItem $source | % {copy $_.FullName $(join-path $dest ($_.name -replace ' '))}
I think your script should almost work, except $_ isn't going to be defined as anything. By using the for-each cmdlet (%), you assign it and then can use it.
Get-ChildItem *.txt | %{Rename-Item -NewName ( $_.Name -replace ' ','' )}
EDIT:
That interpretation was totally wrong. Some people seem to have found it useful, but as soon as you have something being piped, it appears that $_ references the object currently in the pipe. My bad.
I have no problem adding sequential prefixes to filenames. The following works great on the top directory in question.
$path="E:\path\newtest1"
$count=4000
Get-ChildItem $path -recurse | Where-Object {!$_.PSIsContainer -and $_.Name -NotMatch '^\d{4}\s+'} | ForEach -Process {Rename-Item $_ -NewName ("$count " + $_.name -f $count++) -whatif}
BUT if there are files in subfolders within the top directory, these are all completely missed. Whatif reports that for any deeper file it "does not exist".
I have tried the following, based on looking at some pages on other recursion problems, but as you can probably guess I have no clue what it is doing. Whatif shows that it does at least pickup and rename all the files. But the following does it too much and makes multiple copies of each file with each number:
$path="E:\path\newtest1"
$count=4000
Get-ChildItem -recurse | ForEach-Object { Get-ChildItem $path | Rename-item -NewName ("$count " + $_.Basename -f $count++) -whatif}
Really keen to get some guidance on how to get the first of these two snippets to work to find all files in all subdirectories and rename them with sequential number prepended.
Try it like so:
Get-ChildItem $path -recurse -file | Where Name -NotMatch '^\d{4}\s+' |
Rename-Item -NewName {"{0} $($_.name)" -f $count++} -whatif
When you supply $_ as an argument (not a pipeline object), that gets assigned to the Path parameter which is of type string. PowerShell tries to convert that FileInfo object to a string but unfortunately the "ToString()" representation of files in nested folders is just the filename and not the full path. You can see this by executing:
Get-ChildItem $path -recurse -file | Where Name -NotMatch '^\d{4}\s+' | ForEach {"$_"}
The solution is either to A) pipe the object into Rename-Item or B) use the FullName property e.g. Rename-Item -LiteralPath $_.FullName ....
