Remove numbers from all files in a folder - powershell

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+') }

Renaming files within a ton of subfolders

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.

Powershell rename multiple files

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}

PS to rename directory of files using only the first 4 characters

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}

Replace Part of File Name Powershell

I have files that are generated every morning:
Default_20140227_05.00.29.csv
Default_20140226_05.00.29.csv
I would like to rename the files:
VOD_20140227_05.00.29.csv
VOD_20140226_05.00.29.csv
I would basically be replacing Default with VOD.
I am using Powershell 1.0. Any help would be greatly appreciated.
simplified:
ls *.csv | Rename-Item -NewName {$_.name -replace "Default","VOD"}
I do not have PowerShell 1.0 to test, but assuming you are running this in the folder where files reside, you can try:
Get-ChildItem Default_*.csv |Rename-Item -NewName {$_.name -replace '^Default','VOD'}
gci | ?{$_.Name -like "Default*"} | % {$newname = ([String]$_).Replace("Default","VOD"); Rename-item $_ $newname}
A more explanatory version:
$DefaultFiles = Get-ChildItem | Where-Object {$_.Name -like "Default*"}
ForEach($File in $DefaultFiles)
{
$newname = ([String]$File).Replace("Default","VOD")
Rename-item -Path $File $newname
}
If you're looking for a generic version that will take your find and replace as parameters and log out what you've renamed (handy, imo), here's one building from Cole9350's answer:
$Find = $args[0]
$Replace = $args[1]
$TargetFiles = Get-ChildItem | Where-Object {$_.Name -like "*$Find*"}
ForEach($File in $TargetFiles)
{
$newname = ([String]$File).Replace($Find,$Replace)
write-host "Renaming $File to $newname"
Rename-item -Path $File.PSPath $newname
}
And if you want it recursive, just add -Recurse after Get-ChildItem

rename files in powershell

I would like to ask for help in renaming files in given folder.
I would like to change characters "vol._" to "vol."
thanks for help
gci c:\folder_path | ? {$_.name -match 'vol._'} |
rename-item -newname {$_.name -replace 'vol._','vol.'} -whatif
Take a look at the output and if everything works fine remove whatif switch
edit. If you need to rename files even in subfolders you have to apply a little change
gci c:\folder_path -rec | ? {!$_.psiscontainer -and $_.name -match 'vol._'} |
rename-item -newname {$_.name -replace 'vol._','vol.'} -whatif
What about:
gci c:\folderpath -include vol._* | rename-item -newname {$_.name -replace 'vol._', 'vol.'}
