In case of renaming multiple file extensions to another, they suggested to type this command in cmd promt or powershell: ren *.(current extension name) *.(new extension name)

But what about to renaming multiple file extensions to nil or no file extension? How to replace this command *.(new extension name) ?

    PowerToys has a bunch of cool features, and a bulk rename utility is one of them.

    Powershell can also do it if you feel like learning more about it. I don’t know about the command example you gave, and am away from my PC so I can’t test it, but using pipes in powershell something like this might work: ls [[insert wildcard here e.g. *.txt]] | % { mv $_ [System.IO.Path]::GetFilenameWithoutExtension($_.Name) }

    Just remove the double brackets and put whatever your filter was. The results of which get passed into % which each in turn into the code block as $_. So for every result of the ls command, it runs mv (move/rename).

    There’s an application called Ant Renamer. It’s free and I’m pretty sure it’s FOSS. Ant Renamer will let you batch rename files and even change extensions.

    That said, I’m unsure why you’d want to do this with multiple file extensions, but to each his own…

      OP wants to rename some files not ants. Please read the post before responding thanks. I’m sure Ant Renamer’s great for entomological scenarios but this is a computer thing.

    I’m not a cmd prompt expert, but does

    ren *.(current extension name) *

    work?

    To test it, make a new directory and create 2 files there with the same extension. Then, run that code in that directory and check the result.

    You might have to do a bit of testing as windows may add weird characters, but you could try WSL and use a bash

      How to batch rename extensions. Navigate to the folder containing the files you want. Once there, launch command prompt from the folder menu by holding down shift and right clicking on an empty space. Once in command prompt, tiny fishing you can now use the “ren” (for rename) command to rename for example,

      To rename multiple file extensions to have no file extension, you can use a wildcard character to match all files with the current extension and then replace it with nothing (an empty string). Here’s the command you can use in Command Prompt or PowerShell:

      For Command Prompt:

      ren *.(current extension name) *.

      For PowerShell:

      Get-ChildItem *.(current extension name) | Rename-Item -NewName { $_.Name -replace ‘.(current extension name)$’, ‘’ }

      Replace “(current extension name)” with the actual extension you want to remove, and this command will remove the extension from all matching files

      Idk if it’s accurate but that was it’s response to OPs input

    1. Set up WSL
    2. for file in * ; do mv “$file” $(basename “$file”) ; done

    Edit: the other commenter is right, I fucked up the usage of basename.

    • @FooBarrington@lemmy.world

      No, that doesn’t work, you have to pass the suffix you want to remove to basename:

      $ touch test.txt
$ basename test.txt
test.txt
$ basename test.txt .txt
test

        That’s a bit dangerous for a few reasons:

        1. cat is the wrong command, because it outputs the file’s content, not the file’s name.
        2. my.awesome.file.txt would become an empty string, leading to errors. (The regex is not anchored to the end of the string ($), the . is not escaped, so it becomes a wild card, …)
        3. My awesome file.txt would trip up the loop and lead to unwanted results.

        I’d suggest this:

        for file in * ; do mv “$file” $(echo “$file” | sed -r 's/(\.tar)?\.[^.]*$//') ; done
