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 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.
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 '\[','' -replace '\]','' }
I know I can convert all filenames in a given folder to uppercase with the following:
Get-ChildItem -Path your_path -Recurse | Rename-item -NewName {$_.name.ToUpper()}
However, how can I capitalize only the first two letters of all filenames in a folder?
i.e.
ls123456_This_is_a_Test.pdf --> LS123456_This_is_a_Test.pdf
re98765_Another_Test.pdf --> RE98765_Another_Test.pdf
Thanks

Use the .SubString() method to separate the first two characters
## Q:\Test\2018\07\21\SO_51451148.ps1
$Folder = (Get-Item '.').FullName
Get-ChildItem -Path $Folder -File -Recurse |
Where-Object Name -match '^[a-z]{2}.' |
Rename-item -NewName {"{0}{1}" -f $_.Name.SubString(0,2).ToUpper(),
$_.Name.Substring(2)} -WhatIf
If the output looks OK, remove the -WhatIf parameter
try it :
Get-ChildItem "c:\temp" -file | %{
if ($_.Name.Length -gt 1)
{
$NewName="{0}{1}" -f $_.Name.SubString(0, 2).ToUpper(), $_.Name.Substring(2)
}
else
{
$NewName=$_.Name.ToUpper()
}
Rename-item $_.FullName $NewName -WhatIf
}
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 a folder with a load of files with a random number in the middle. they are in this format:
Input-4535344534x-results.xml
Input-4535344534y-log.xml
Input-4535344534z-main.xml
Is there any way to remove the numbers through a .bat file or something I can execute as part of an ssis package so that I am left with:
Input-x-results.xml
Input-y-log.xml
Input-z-main.xml
I tried running this in powershell but it does not seem to work
Get-ChildItem -Filter *.xml | Rename-Item -NewName {$_.Name -replace '^[0-9_]+'}
Thanks
Something like this should work:
Get-ChildItem -Filter *.xml |
Foreach-Object {
$newName = $_.Name -replace "(\w+-)(\d+)(\w+)",'$1$3'
Rename-Item -Path $_.FullName -NewName $newName
}
UPDATE: Simplifying
Get-ChildItem -Filter *.xml | Rename-Item -NewName {$_.Name -replace "(\w+-)(\d+)(\w+)",'$1$3'}
Let me know if this helps.
ls Input-*.xml -n | % { mv $_ ($_ -replace '\d+') }
