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

Hello I would like to know is there a way to replace multiple filenames from parent folder?
I was able to rename multiple files using command below, but I have to access each folder first to rename multiple files.
dir .\* -include ('*.mp4','*.srt') | Rename-Item -NewName { $_.Name -replace '\[','' -replace '\]','' }
I was trying to replace dir .\* to dir .\**\* to select from parent folder but didn't work.
What am I missing?
You can do that by adding the -Recurse switch to Get-ChildItem (dir is alias to Get-ChildItem).
When searching for files that contain square brackets, you need to use the -LiteralPath parameter.
Also, be aware that there is a snag if you pipe the results from that directly to Rename-Item..
When doing so, Get-ChildItem may pick up the already processed files again, wasting time of course, so to prevent that you can either do:
$rootFolder = 'X:\WhereTheFilesAre'
(Get-ChildItem -LiteralPath $rootFolder -Include '*.mp4','*.srt' -File -Recurse) |
Rename-Item -NewName { $_.Name -replace '\[|]' }
or
$rootFolder = 'X:\WhereTheFilesAre'
$files = Get-ChildItem -LiteralPath $rootFolder -Include '*.mp4','*.srt' -File -Recurse
foreach ($file in $files) {
$file | Rename-Item -NewName { $file.Name -replace '\[|]' }
}
In additional to marsze's concise answer and realizing this isn't really a performance question:
-Include is much slower than -Filter because it filters after retrieving from the file system. Whereas, -Filter has the file system do the heavy lifting. In essence -Filter is a nuanced version of moving filtering operations left in the command/pipeline to improve performance. However, -Filter doesn't take multiple values! That said, you may still be able to exploit this characteristic using a loop, something like:
'*.mp4','*.srt' |
ForEach-Object{
Get-ChildItem .\ -Filter $_ -File
} |
Rename-Item -NewName { $_.Name -replace '\[|\]' }
-File works even though you are using -Recurse and may carry a modest performance improvement. I also shortened the -replace to 1 operation which can only help further.
What you probably want is the -Recurse switch:
dir "the folder" -Recurse -Include ('*.mp4','*.srt')
Note that this will recurse all levels of subdirectories.
I just found out I could use dir . to select all files (with specific file types), including files in subdirectories.
dir . -Recurse -Include ('*.srt', '*.mp4') | Rename-Item -NewName { $_.Name -replace '\[|\]','' }
I am doing some batch file name updates and am having trouble including folders. I have it currently set to target only specific file types, but I also want to include folders. Since folders don't have an extension I am unsure how to specify folders in the "-include" string. Any help would be greatly appreciated.
Here is what I am currently working with, but it ignores folders when I would like them included.
Get-ChildItem k:/toolbox/powershell -Include *.gif, *.jpg, *.png, *.xls,
*.xlsx, *.ppt, *.pptx, *.doc, *.docx, *.pdf -recurse | where {$_.name -match
"_"} | foreach {
$New=$_.name.Replace("_","-")
Rename-Item -path $_.Fullname -newname $New -passthru
}
(Get-Item '~\Desktop\*') | foreach { $FolderName = $_.name.Replace("_","-"); Rename-Item -path $_.fullname -newname $FolderName -passthru }
I would just add 2nd statement:
Get-ChildItem "k:/toolbox/powershell" -Recurse |where mode -eq d----- | where {$_.name -match "_"} | foreach {$New=$_.name.Replace("_","-")
Rename-Item -path $_.Fullname -newname $New -passthru }
If you run Get-ChildItem "k:/toolbox/powershell" you will receive a list of items where the "Mode" is "d-----" for directories, hence you can use that filter criteria for directories
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 need to write a script in PowerShell which renames all the files with no extension under a given directory and all subfolders. By renaming I mean to add an extension e.g. ".html" to the file which doesn't have it.
So far I've tried to build something like this:
Get-ChildItem -Path 'C:\dev\blah' -Filter *. -Recurse | ForEach-Object {
Rename-Item -Path $_.FullName -NewName ($_.FullName + ".html")
}
You need to exclude folders from the enumerated items. Use the switch -File if you're running PowerShell v3 or newer, otherwise add a Where-Object filter. Also, you don't need ForEach-Object since Rename-Item accepts pipeline input.
Get-ChildItem -Path 'C:\dev\blah' -Filter *. -Recurse | Where-Object {
-not $_.PSIsContainer
} | Rename-Item -NewName {$_.Name + ".html"}
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.
