I have a lot of files in a directory containing square brackets for example:
Filename 1 [12454365].txt
I tried the following script but it's giving me the an error.
get-childitem -recurse | foreach { move-item -literalpath $_.name ($_.name -replace '\[.*\]', '')}
Error message
move-item : A device attached to the system is not functioning.
Only want to remove square brackets not everything in between!
If you specify -Recurse, you will need to specify the file with FullName because it will be targeted other than the current directory.
(Get-ChildItem -File -Recurse) | foreach {
$dest = Join-Path $_.DirectoryName ($_.Name -replace "[\[\]]")
Move-Item -LiteralPath $_.FullName $dest
}
Also, it is better to use Rename-Item for file renaming.
(Get-ChildItem -File -Recurse) | Rename-Item -NewName { $_.Name -replace "[\[\]]" }
I believe the issue is that you are replacing the brackets and everything in between.
Get-ChildItem * -Filter "*`[*`]*" | Rename-Item -NewName { $_.name -replace '\[','' -replace '\]','' }

How could I modify name of every file by adding _ before the filename extension in a Get-ChildItem -Include without calling 3 times a Foreach.
My script works, but I would like to simplify it by using -Include and not -Filter.
function renommer_fichier {
$files = Get-ChildItem -Path C:\mestp\mesFichiers -Filter *.jpg
Foreach ($file in $files)
{
$file | Rename-Item -NewName { $_.Name -replace '.jpg', '_.jpg' }
}
$files = Get-ChildItem -Path C:\mestp\mesFichiers -Filter *.mp3
Foreach ($file in $files)
{
$file | Rename-Item -NewName { $_.Name -replace '.mp3', '_.mp3' }
}
$files = Get-ChildItem -Path C:\mestp\mesFichiers -Filter *.mpeg
Foreach ($file in $files)
{
$file | Rename-Item -NewName { $_.Name -replace '.mpeg', '_.mpeg' }
}
}
Unfortunately, the -Include parameter - which supports specifying multiple patterns - doesn't work as one would intuitively expect:
Use Get-Item instead of Get-ChildItem and append \* to the input path to make -Include work as intended.
See this answer for background information.
Use the .BaseName and .Extension properties in the delay-bind script block you're passing to Rename-Item to facilitate inserting _ before the filename extension.
Get-Item -Path C:\mestp\mesFichiers\* -Include *.jpg, *mp3, *.mpeg |
Rename-Item -WhatIf -NewName { $_.BaseName + '_' + $_.Extension }
Note: The -WhatIf common parameter in the command above previews the operation. Remove -WhatIf once you're sure the operation will do what you want.
I have the following code but it is renaming folders and files. When i use basename it says the file i get an error that says the Source and destination path must be different.
I want to rename sd^fks.pdf to sd_fks.pdf
Get-ChildItem $dstpath -Recurse | `
Where-Object {$_.Name -match '^'} | `
Rename-Item -NewName { $_.Name -replace '^','_' }
Escape the circumflex character. Stick to the Name attribute. You might want to add -File to Get-ChildItem to only get files:
Get-ChildItem $dstpath -File -Recurse | Where-Object {$_.Name -match '\^'} | Rename-Item -NewName {$_.Name -replace '\^','_'}
You don't need the Where-Object clause for this. Instead use Filter which makes the code run faster aswell:
Get-ChildItem -Path $dstpath -Filter '*^*' -Recurse -File | Rename-Item -NewName { $_.Name -replace '\^','_' }
When in doubt, regex escape:
[regex]::escape('^')
\^
'^' means 'the beginning of the line in regex:
'hi' -replace '^','prefix-'
prefix-hi
Or plug the expression in at https://regex101.com and see what it says.
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)"
}
I have to go through many levels of child folders and remove special characters that are invalid in SharePoint, mainly '#&'
I have scoured the internet trying different commands; rename-item/move-item, variations of the two, all to no avail. The closest i've gotten is using:
Get-ChildItem -Recurse | Rename-Item -NewName {$_.Name -replace'[!##&]','_'}
but i keep getting this error: Rename-item: Source and destination path must be different.
Could someone point me in the right direction?
Regards
That error only happens when you attempt to rename a directory to the same NewName as the current name, you can safely ignore it.
Add -ErrorAction SilentlyContinue to silently suppress the error message:
Get-ChildItem -Recurse | Rename-Item -NewName {$_.Name -replace'[!##&]','_'} -ErrorAction SilentlyContinue
You need to filter out the files that you're not planning to rename:
Get-ChildItem -Recurse |
Where-Object { $_.Name -match '[!##&]' } |
Rename-Item -NewName {$_.Name -replace '[!##&]','_'}
something like this may work
dir -Recurse -File | ? basename -Match '[!##&]' | % {
# if the file.txt already exists, rename it to file-1.txt and so on
$num = 1
$base = $_.basename -replace'[!##&]', '_'
$ext = $_.extension
$destdir = Split-Path $_.FullName
$newname = Join-Path $destdir "$base$ext"
while (Test-Path $newname) {
$newname = Join-Path $destdir "$base-$num$ext"
$num++
}
ren $_.fullname $newname
}
I have this awesome powershell script that will remove special characters from filenames:
Function Rename-Files($path)
{
Get-ChildItem -path $path |
Foreach-Object {
$newName = $_.name -replace '[^A-Za-z0-9-_ ]', ''
if (-not ($_.name -eq $newname)){
Rename-Item -Path $_.fullname -newname ($newName)
}
}
} #end function
Rename-Files -path "C:\somepath"
i would like to know whether it is possible to get this working not just on the top directory but recursively through the entire directory structure?
Just add the -Recurse Get-ChildItem parameter. e.g.
Get-ChildItem -Recurse -path $path
