Here is a Python script I wrote that pads zeroes depending on the largest number present and ignores non-numbered files in the given directory.

You can then use the zeropad.sh script as follows. Save the above to a file called zeropad.sh and then do the following command to make it executable chmod +x. Here’s how to do that in bash #!/bin/bash In other words I replace file1.png with file001.png and file20.png with file020.png and so on. Os.rename(os.path.join(path,oldname), os.path.join(path,newname)) zfill(4) + ".png") for x in os.listdir(path) if x.startswith("output_") and x.endswith(".png")] You could compile a list of valid filenames assuming that all files that start with "output_" and end with ".png" are valid files: l =. Os.rename(os.path.join(path, filename), os.path.join(path, new_filename)) New_filename = prefix + "_" + num + ".png" ![]()
