Python script to rename files in directory, transforming spaces to hyphens and the chars to lowercase

rename.py

import os

""" 
Renames the filenames within the same directory to be Unix friendly
(1) Changes spaces to hyphens
(2) Makes lowercase (not a Unix requirement, just looks better ;)

Usage:
python rename.py
"""

path =  os.getcwd()
filenames = os.listdir(path)

for filename in filenames:
    os.rename(filename, filename.replace(" ", "-").lower())

What about changing possible single adding to them leading zeros, something like:
file-1.txt file-2.txt --> file-001.txt file-002.txt

How about renaming with appending zeroes like name00.txt,name01.txt and so on to all files at once?

The internet is a beautiful place my friends, cherish.

Dear all. i want to write simple script that change entire file name in folder to test1,test2,test3 so on. actually i did it was so easy. but the thing i want is that the file name should change constantly.for instance, test1,test2,test3 and when i add example.txt file to folder the file must be changed to Test4. i got file exist error. by the way i don't want to remove file itself,only name,file content shouldn't be changed. hop i could make it clear to u.

What if I want to change names and not directories? 🐙

@Hellstorm90 use os.path.isfile to check if file (or os.path.isdir to check if directory)

works great exactly what i needed

Thanks :) works great for me.

Thanks..! it worked for me. Though my requirement is bit different.

Thank you for sharing. Very useful "as is" and a useful little script for learning :)

I have two cameras in the raspberry pie that every time it overwrites the name of the image, for example, image 1 and image 2,
when I run it again, it overwrites on image 1 and image 2, how can I rename previous images to avoid overwriting?

Thank you

Thank you so much,,, I searched so many links to rename my files in a folder with a regular expression/pattern none worked, But this.

Is there any way to extend this script down the tree to rename folders and files within folders???

Thank you, that's what i was looking for.

Does it read the names in ascending order?

Great! It’s simple, it works. 👍 Thank you!

There's a simpler way to do this using the linux rename command, if you'd like:

rename --force 's/ /-/g' *

If you run that on the CLI it'll rename all files in the current directory -- exchanging spaces for dashes.

@rdegges that does not make uppercase -> lowercase though.

how can i change only the first letter of a filename into uppercase??

how about removing leading space in multiple files in a directory?
i have many files in a directory and each one start with a space. so how to batch remove that?
