How do I make a script like this in the command line?

Question

I would like to create a script that lists every files, which first four characters of the filename match/similar. I would need this because I have hundreds of files and I don't want to delete the duplicated files manually. Somebody suggested me to write a script to the command line. But unfortunately I can't programming. :(

e.g.

xyzvw.txt

xyzvq.txt

qwerty.txt

qwertz.txt

So xyzvw.txt and xyzvq.txt are have the same first four character. I want to find every files like these.

I also tried duplicator deleter programs, but it only deleted a few duplication.

Can anyone help?

Answer 1

Is this what you are looking for?

$folder = 'C:\temp\'
$First4 = Get-ChildItem $folder -file | foreach { $_.Name.Substring(0,4)} | Select-Object -Unique
"Here are the unique prefixes that we found."
$First4

foreach ($four in $First4) {
    ""
    "--------- $four -----------"
    (Get-ChildItem $folder -Filter ($four + "*")).fullname
}    

Answer 2

I found a program, which you can find similar files and very easy to use.
