Thanks for reading! Please feel free to share any tips or advice for working with Python's pathlib, os, and os.You can use batch file renaming to delete part of a filename, too. Add output logs for filename changes-currently, text is output to the console, but could easily be captured in a log file.(Originally, all matches were replaced-hence the switch to using. In rn all, build in an option to specify how many substring matches are replaced.In rn and rn all, build in handling for spaces-currently, there is no working way to remove a substring without adding any characters!.If you'd like to tackle some specific issues with the current code, here are a few on my list: Please feel free to fork/clone/hack apart as you wish! If you do, I'd love to hear how you're using the script, whether it's for music sample libraries or something else entirely. Once again, here's the link to the GitHub repo: That's it! Now you're ready to mass-rename your files! :) rpartition() until it finds a match in its parent directories, potentially causing directory errors! You've been warned. Note: This method currently encounters errors when a file does NOT contain the given input! Instead, it will continue searching with. Calling os.rename(src, dst) will change the filename in your system. If found, that one instance is replaced with the given string output, and reconcatenated as the string dst.

Here, src.rpartition(input) allows us to search the filename-string src from right-to-left, searching for a match for the string input.

rpartition ( input ) dst = head + output + tail os. In addition to the above snippet, we see os.path.isfile() in action here:ĭef rename_partial_filename ( filename, input, output ): src = str ( filename ) head, sep, tail = src.

os.path.isfile(path) - returns true if the supplied path is an existing file, or false if not.

os.path.isdir(path) - returns true if the supplied path is an existing directory, or false if not.

The os.path module provides a number of useful validation methods, including two which are used in this script: In the snippet above, we also see that os.path.isdir() is used to throw an error if no directory is found. Otherwise, when user input is cd followed by something else, new_path is a string created by using os.path.join to add the contents of user_input onto the end of current_directory. , a new_path string is created from current_directory.parent, and is turned back into a Path object with current_directory = pathlib.Path(new_path). isdir ( current_directory ): print ( "Not a valid directory!" ) current_directory = temp_directory join ( current_directory, user_input ) current_directory = pathlib. If user_input = "cd" : temp_directory = current_directory if user_input = "." : new_path = current_directory. # inside main loop, after getting user_input realpath ( './drum-samples' ) # set default path hereĬurrent_directory = pathlib.

See script.py line 37 (as of this writing) for the code to change: The only configuration you will need to do is setting a default path. As a CLI, file-renamer also provides a way to navigate a filesystem to modify files in different folders quickly and easily from the command line.Īfter cloning the repo to your computer, you can run file-renamer with $ python3 script.py in the repo's directory. I got really tired of renaming them one-by-one, so I wrote my first Python script, file-renamer, as a CLI to do mass-renaming!īasically, I wanted a way to change or remove specific strings from multiple filenames at once.

One drawback of the my main drum machine is that it limits readable filenames-anything after a certain number of characters is cut off, and any name-collisions will point to the first file with that name.Ī lot of my music sample library has folders full of long, repetitive filenames, like this: One of my hobbies is making electronic music, and thanks to resources like, I have tons and tons of audio files to manage.
