My media files have the following names:
s01ep01
S01ep02
etc.
I need to remove the letter "p" so my program can properly cross reference the episodes.
Something like this should do:
Get-ChildItem 'C:\your\folder' |
Rename-Item -NewName { $_.Name -replace '^(s\d+e)p', '$1' }

I have been looking around for a way to quickly and easily rename hundreds os files in one go.
something where I only have to change smalle parts for it to be reused somewhere else.
So i ended up starting to make this script. shown below...
the output should come out like this:
Show Title - SXX.EXXX - Episode title - [release year]
the raw files all looks like this:
XXX Episode title [release year]
It does not work right now. and i haven't been able to see why yet.
Whenever i run it, it does nothing. but i do not get any error message.
$ShowTitle = "My Title -"
$SeasonNumber = "02"
# Getting all child files (In ALL subfolders)
$files = Get-Childitem –Path Get-Location -Recurse |
Where-Object { $_.Name -match $_.Name } |
# Insert a ' - ' between the episode number and the episode text.
Rename-Item -NewName {$_.BaseName.insert(5,'-') + $_.Extension} |
# Append title and season number to the beginning of the file.
Rename-Item -NewName { $ShowTitle + "S" + $SeasonNumber + ".E" + $_.Name} |
# Makes a "-" between episode title and year of release.
Rename-Item -NewName { $_.Name -replace '\[', '- [' }
it worked on a smaller scale before. like this:
$files = Get-Childitem –Path "C:\Users\user\Videos\Series\show\Season x" -Recurse |
Where-Object { $_.Name -match 'show title' } |
Rename-Item -NewName { $_.Name -replace '\[', '- [' }
But i would like to do all the steps above in one go.
Can someone give me a hint so I can find the right answer to my little problem?
Thank you in advance.
You've got a lot of bugs here.
Get-Childitem –Path Get-Location -Recurse
This doesn't make sense. You're looking for a file or folder in the current directory with the literal name Get-Location. Like C:\Get-Location\. If you want to get the files in the current directory, you just don't specify the -Path parameter: Get-ChildItem -Recurse.
Where-Object { $_.Name -match $_.Name } is kind of nonsense code? The right hand side of the -match operator is going to be treated as a regular expression. That means . means "any character", square brackets and parentheses have special meaning, and so on. It's often going to always be true, but I can't imagine that you actually want to do what that says. It's very possible to construct a valid filename that doesn't match a regular expression with the same string value. For example '[01] File.avi' -match '[01] File.avi' is false.
Second, the -NewName parameter takes a string, while {$_.BaseName.insert(5,'-') + $_.Extension} is a ScriptBlock. That may work because some parts of Powershell allow that, but idiomatically I would say that it's wrong because it will not work consistently. A better option would be to use a string with embedded subexpressions like -NewName "$($_.BaseName.Insert(5,'-'))$($_.Extension)"
Finally, Rename-Item doesn't pass any output to the pipeline without the -PassThru parameter. You'd only process the first item and then I imagine the system would complain of an empty pipeline or only the first Rename-Item would do anything.
Try something like this:
$ShowTitle = "My Title -"
$SeasonNumber = "02"
# Getting all child files (In ALL subfolders)
$files = Get-Childitem -Recurse |
Where-Object { $_.Name -match 'some value or delete this command if you want all files' } |
# Insert a ' - ' between the episode number and the episode text.
Rename-Item -NewName "$($_.BaseName.Insert(5,'-'))$($_.Extension)" -PassThru |
# Append title and season number to the beginning of the file.
Rename-Item -NewName "$($ShowTitle)S$($SeasonNumber).E$($_.Name)" -PassThru |
# Makes a "-" between episode title and year of release.
Rename-Item -NewName "$($_.Name -replace '\[', '- [')" -PassThru
I have a batch of files with names like: 78887_16667_MR12_SMITH_JOHN_713_1.pdf
I need to retain the first three sets of numbers and remove everything between the third "_" and "_1.pdf".
So this: 78887_16667_MR12_SMITH_JOHN_713_1.pdf
Becomes this: 78887_16667_MR12_1.pdf
Ideally, I'd like to be able to just use the 3rd "_" as the break as the third set of numbers sometimes includes 3 characters, sometimes 4 characters (like the example) and other times, 5 characters.
If I used something like this:
Get-ChildItem Default_*.pdf | Rename-Item -NewName {$_.name -replace...
...and then I'm stuck: can I state that everything from the 3rd "" and the 6th "" should be replaced with "" (nothing)? My understanding that I'd include ".Extension" to also save the extension, too.
You can use the -split operator to split your name into _-separated tokens, extract the tokens of interest, and then join them again with the -join operator:
PS> ('78887_16667_MR12_SMITH_JOHN_713_1.pdf' -split '_')[0..2 + -1] -join '_'
78887_16667_MR12_1.pdf
0..2 extracts the first 3 tokens, and -1 the last one (you could write this array of indices as 0, 1, 2, -1 as well).
Applied in the context of renaming files:
Get-ChildItem -Filter *.pdf | Rename-Item -NewName {
($_.Name -split '_')[0..2 + -1] -join '_'
} -WhatIf
Common parameter -WhatIf previews the rename operation; remove it to perform actual renaming.
mklement0 has given you a good and working answer. Here is another way to do it using a regex.
Get-ChildItem -Filter *.pdf |
ForEach-Object {
if ($_.Name -match '(.*?_.*?_.*?)_.*(_1.*)') {
Rename-Item -Path $_.FullName -NewName $($Matches[1..2] -join '') -WhatIf
}
}
I have a directory that consists of a number of text files that have been named:
1Customer.txt
2Customer.txt
...
99Customer.txt
I am trying to create powershell script that will rename the files to a more logical:
Customer1.txt
Customer2.txt
...
Customer99.txt
The prefix can be anything from 1 digit to 3 digits.
As I am new to powershell, I really don't know how I can achieve this. Any help much appreciated.
The most straigth forward way is a gci/ls/dir
with a where matching only BaseNames starting with a number with a
RegEx and piping to
Rename-Item and building the new name from submatches.
ls |? BaseName -match '^(\d+)([^0-9].*)$' |ren -new {"{0}{1}{2}" -f $matches[2],$matches[1],$_.extension}
The same code without aliases
Get-ChildItem |Where-Obect {$_.BaseName -match '^(\d+)([^0-9].*)$'} |
Rename-Item -NewName {"{0}{1}{2}" -f $matches[2],$matches[1],$_.extension}
Here is one way to do it:
Get-ChildItem .\Docs -File |
ForEach-Object {
if($_.Name -match "^(?<Number>\d+)(?<Type>\w+)\.\w+$")
{
Rename-Item -Path $_.FullName -NewName "$($matches.Type)$($matches.Number)$($_.Extension)"
}
}
The line:
$_.Name -match "^(?<Number>\d+)(?<Type>\w+)\.\w+$")
takes the file name (e.g. '23Suppliers.txt') and perform a pattern match on it, pulling out the number part (23) and the 'type' part ('Suppliers'), naming them 'Number' and 'Type' respectively. These are stored by PowerShell in its automatic variable $matches, which is used when working with regular expressions.
We then reconstruct the new file using details from the original file, such as the file's extension ($_.Extension) and the matched type ($matches.Type) and number ($matches.Number):
"$($matches.Type)$($matches.Number)$($_.Extension)"
I'm sure there's a nicer way to do this with regex, but the following is a quick first go at it:
$prefix = "Customer"
Get-ChildItem C:\folder\*$prefix.txt | Rename-Item -NewName {$prefix + ($_.Name -replace $prefix,'')}
how do I remove every character after a _ in folder names
ex
folder names
307456_ajksndkajsdna_asd_busd to 307456
780451_dsadafg_4565 to 780451
edit: also remove the _
I am using windows 7
In PowerShell, you can use the -split operator to split the string by _ and keep only the first part:
$number,$null = '307456_ajksndkajsdna_asd_busd' -split '_'
The value of $number is now 307456, the rest has been discarded.
If you want to rename all child folders in a folder to just the first number, use Get-ChildItem to retrieve the files, and Rename-Item to rename them:
Get-ChildItem -Path C:\folder\name |Where-Object {$_.PSIsContainer} |Rename-Item -NewName { $($_.Name -split '_')[0] }
I want to remove the last 11 characters of multiple files names. For example
I have these file names:
ABCDE_2015_10_20
HIJKL_2015_10_20
MNOPQ_2015_10_20
RSTUV_2015_10_20
would like to rename them to
ABCDE
HIJKL
MNOPQ
RSTUV
I have tried using the follwing code:
Get-ChildItem 'E:\Thomson Reuters\Stage' | rename-item -newname { [string]($_.name).substring($_.name.length -14) }
Can anybody tell me where I am going wrong?
You're almost there, you just need to tell substring exactly where to start and end:
Get-ChildItem 'E:\Thomson Reuters\Stage' | rename-item -newname { $_.name.substring(0,$_.name.length-11) }
By passing two integers to substring you give it the StartIndex and Length of the string you want to capture. See here for the documentation
Just to add to the response from arco444:
Get-ChildItem 'E:\Thomson Reuters\Stage' -filter *.txt | rename-item -NewName {$_.name.substring(0,$_.BaseName.length-6) + $_.Extension -replace "_"," "}
This would rename all .txt files in the directory, remove the last 6 characters of the file name, replace any remaining underscore in the filename with a space but still retain the file extension.
So assuming these were text files you would see something like this:
ABCDE_2015_10_20.txt
HIJKL_2015_10_20.txt
MNOPQ_2015_10_20.txt
RSTUV_2015_10_20.txt
Become this:
ABCDE 2015.txt
HIJKL 2015.txt
MNOPQ 2015.txt
RSTUV 2015.txt
As you want to split the file name at the 1st underscore,
use the .split() method or -split operator with the zero based index [0].
rename changing the BaseName and keeping the Extension
Get-ChildItem 'E:\Thomson Reuters\Stage' |
Rename-Item -NewName { $_.BaseName.Split('_')[0] + $_.Extension }
