I have a large number of files in a number of directories with this type of naming convention:
"BU1_KCG_RANDOM_030515.csv", etc.
I need to remove the 16th and 17th characters. So the new file name would be "BU1_KCG_RANDOM_0515.csv".
How can I iterate the multiple directory renaming accordingly?
So far I have got the below, but I am not sure what would come next.
Get-ChildItem -Filter *.csv -Recurse | Rename-Item -NewName {$_.Name..................}
Using -replace:
Get-ChildItem -Filter *.csv -Recurse |
foreach { $_ | rename-item -newname ($_.Name -replace '(.{15})..(.+)','$1$2') }
I much prefer mjolinor's answer, but you can always do things in a different way with PowerShell. Since you can index a string like a char array we can use a little array notation to get the characters you want as well.
$oldname = "BU1_KCG_RANDOM_030515.csv"
$newname = -join $oldname[0..14 + 17..($oldname.Length)]
$newname
BU1_KCG_RANDOM_0515.csv
We also need to use -join to convert the array back into a string.
Bit basic, eg doesn't check if the file has already been renamed, but should get you to the next step
gci -filter *.csv -rec | % { Rename-Item $_ -newname ($_.Name.substring(0,15) + $_.Name.substring(17)) }
where
gci = get-childitem
% = for-each
$_ = this (inside the for-each)

I need to limit the files affected to Example*.pdf. The files have 1-3 digits in the names and I need to standardize them. So Example_1.pdf -> Example_001.pdf while Example_100.pdf -> Example_100.pdf
The first part renamed files to Example.1.pdf so I could parse them with a single delimiter, but it gave me errors on the second step (cmdlet rename-item at command pipeline position 1 supply values for the following parameters: path)
Get-ChildItem of* | rename-item -newname { $_.Name -replace '_','.' }
Get-ChildItem of* |
foreach {
$nameArray = $_.Split('.')
$ExampleNumber = $nameArray[1]
rename-item -path $Path -newname $nameArray[0]+$ExampleNumber+$nameArray[2]
}
But if I can get something like this to work then I can play around with $ExampleNumber
Then I tried using regular expressions. Had this worked it would have padded the single digit files and then I could make a second pass for double digit files. But it didn't rename anything.
Get-ChildItem ex* | rename-item -newname { $_ -replace '(.*)(\d{1})\.pdf', 'Example_0$2.pdf'}
Any help is appreciated.
Note the $_ inside the -NewName block is of type FileInfo.
Here's my suggestion:
Get-ChildItem ex* | Rename-Item -NewName {
[void]($_.Name -match "\d+")
$_.Name -replace "\d+", (([int]$Matches[0]).ToString("000"))
}
Or alternatively:
Get-ChildItem ex* |
Rename-Item -NewName {
$_.Name -replace "\d+", (([int][regex]::match($_.Name, "\d+").value).ToString("000"))}
I have multiple files from camera with names "00010001", "00010002", etc. Those are multiple file types (JPG, CR2, xmp, MOV) in one folder (lets say C:\camera).
I need to add 10000 to number in all file names, so it becomes "00020001", "00020002", etc. I guess this could be done with a simple script in powershell, but I have absolute no experience with it. I would be very grateful if someone helped me with it. Thank you.
If the code should also handle files in subfolders of 'C:\Camera', you can use the -Recurse and -Include parameters:
(Get-ChildItem -Path 'C:\Camera' -File -Include '*.JPG','*.CR2','*.XMP','*.MOV' -Recurse) |
Where-Object { $_.BaseName -match '\d{8}' } |
Rename-Item -NewName { '{0:D8}{1}' -f ([int]$_.BaseName + 10000), $_.Extension } -WhatIf
If however this should NOT go any deeper that the root folder 'C:\Camera', then do this:
(Get-ChildItem -Path 'C:\Camera' -File) |
Where-Object { $_.BaseName -match '\d{8}' -and $_.Extension -match '\.(JPG|CR2|XMP|MOV)$' } |
Rename-Item -NewName { '{0:D8}{1}' -f ([int]$_.BaseName + 10000), $_.Extension } -WhatIf
Once you are satisfied the code would create the new filenames as you wish, remove the safety switch -WhatIf
Explanation:
Get the files in the folder that have BaseNames consisting of 8 digits ($_.BaseName -match '\d{8}') and that have an extension of either JPG, .CR2, .XMP or .MOV
Convert that BaseNaem into an interger number and add 10000
Reassemble the file name with the -f format operator, where the template string {0:D8}{1} makes sure all (new) numbers are prefixed with zeroes up to 8 digits
I'm trying to rename a bunch of files using powershell by removing the prefix (which is the same in all files), replacing "+" with a space and setting the remainder to title case. Here's what I have so far:
Where-Object { $_ -Match '^Website\.com_+' } |
ForEach-Object
{
$_ |
Rename-Item -NewName {$_.Name -replace 'Website\.com_','' -replace '\+',' '};
Rename-Item $_.Fullname (Get-Culture).TextInfo.ToTitleCase($_)
}
The first rename works, it removes and formats files properly, but then the second rename says the items don't exist, which makes me think I should just then pass them into another foreach loop in another pipe, but I can't seem to make that work either.
It seems like having 2 rename-items isn't really working and I tried having the title case with the replace and it doesn't seem to work either.
It would be more straight forward to build the name in 2 stages and then do one Rename-Item
Something like below should do what you need
Where-Object { $_ -Match '^Website\.com_+' } |
ForEach-Object {
$BaseName = ($_.Name -replace 'website\.com','' -replace '\+','')
$FinalName = (Get-Culture).TextInfo.ToTitleCase($BaseName)
Rename-Item $_.FullName -NewName $FinalName
}
$_ in your ForEach-Object loop is a snapshot of the item - it won't dynamically change to follow things you do to the underlying file. When you rename the item, $_ represents the old name. So, when you attempt the second rename based on $_.FullName, Rename-Item won't find anything.
A potential solution to your problem of "setting the remainder to title case" would be, outside the loop, do another Get-ChildItem search for anything that falls into this condition, and then rename them separately.
Finally found something that works:
$path = "G:\Downloads\Chrome\test2"
$items = (Get-ChildItem -Path $path -File *.mp4 |
Where-Object { $_ -Match '^Website\.com_+' } |
ForEach-Object{
$_ |
Rename-Item -NewName {$_.Name -replace 'Website\.com_','' -replace '\+',' '} -PassThru
})
$items | % {
Rename-Item -Path $_.FullName -NewName (Get-Culture).TextInfo.ToTitleCase($_.Name)
}
Thanks to everyone who tried to help me!
I am using below Powershell script which successfully traverses through all my case folders within the main folder named Test. What it is incapable of doing is to rename each sub folder, if required, as can be seen in current and desired output. Script should first sort the sub folders based on current numbering and then give them proper serial numbers as folder name prefix by replacing undesired serial numbers.
I have hundreds of such cases and their sub folders which need to be renamed properly.
The below output shows two folders named "352" and "451" (take them as order IDs for now) and each of these folders have some sub-folders with a 2 digit prefix in their names. But as you can notice they are not properly serialized.
$Search = Get-ChildItem -Path "C:\Users\User\Desktop\test" -Filter "??-*" -Recurse -Directory | Select-Object -ExpandProperty FullName
$Search | Set-Content -Path 'C:\Users\User\Desktop\result.txt'
Below is my current output:
C:\Users\User\Desktop\test\Case-352\02-Proceedings
C:\Users\User\Desktop\test\Case-352\09-Corporate
C:\Users\User\Desktop\test\Case-352\18-Notices
C:\Users\User\Desktop\test\Case-451\01-Contract
C:\Users\User\Desktop\test\Case-451\03-Application
C:\Users\User\Desktop\test\Case-451\09-Case Study
C:\Users\User\Desktop\test\Case-451\14-Violations
C:\Users\User\Desktop\test\Case-451\21-Verdict
My desired output is as follows:
C:\Users\User\Desktop\test\Case-352\01-Proceedings
C:\Users\User\Desktop\test\Case-352\02-Corporate
C:\Users\User\Desktop\test\Case-352\03-Notices
C:\Users\User\Desktop\test\Case-451\01-Contract
C:\Users\User\Desktop\test\Case-451\02-Application
C:\Users\User\Desktop\test\Case-451\03-Case Study
C:\Users\User\Desktop\test\Case-451\04-Violations
C:\Users\User\Desktop\test\Case-451\05-Verdict
Thank you so much. If my desired functionality can be extended to this script, it will be of great help.

You can do the following based on what you have posted:
$CurrentParent = $null
$Search = Get-ChildItem -Path "C:\Users\User\Desktop\test" -Filter '??-*' -Recurse -Directory | Where Name -match '^\d\d-\D' | Foreach-Object {
if ($_.Parent.Name -eq $CurrentParent) {
$Increment++
} else {
$CurrentParent = $_.Parent.Name
$Increment = 1
}
$CurrentNumber = "{0:d2}" -f $Increment
Join-Path $_.Parent.FullName ($_.Name -replace '^\d\d',$CurrentNumber)
}
$Search | Set-Content -Path 'C:\Users\User\Desktop\result.txt'
I added Where to filter more granularly beyond what -Filter allows.
-match and -replace both use regex to perform the matching. \d is a digit. \D is a non-digit. ^ matches the position at the beginning of the string.
The string format operator -f is used to maintain the 2-digit requirement. If you happen to reach 3-digit numbers, then 3 digit numbers will be output instead.
You can take this further to perform a rename operation:
$CurrentParent = $null
Get-ChildItem . -Filter '??-*' -Recurse -Directory | Where Name -match '^\d\d-\D' | Foreach-Object {
if ($_.Parent.Name -eq $CurrentParent) {
$Increment++
} else {
$CurrentParent = $_.Parent.Name
$Increment = 1
}
$CurrentNumber = "{0:d2}" -f $Increment
$NewName = $_.Name -replace '^\d\d',$CurrentNumber
$_ | Where Name -ne $NewName | Rename-Item -NewName $NewName -WhatIf
}
$NewName is used to simply check if the new name already exists. If it does, a rename will not happen for that object. Remove the -WhatIf if you are happy with the results.
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.
