I have a directory containing a large number of image files, some of which are in subdirectories. I need to rename all image files matching
*.png, *.jpg, *.jpeg, *.bmp, *.gif using a simple pattern for renaming:
- the same prefix for all files;
- a number with padding zeros and printed as hex string.
My goal is to assign a unique name to all image files, independently of their extension, so that I can then convert them to the same image format without the risk of overwriting those files with the same names.
I was writing a script in order to perform the above procedure (for directory listing, I was inspired by the code snippet of this answer).
for root, dirs, filenames in os.walk(path): for filename in filenames: if filename.endswith((".jpeg", ".jpg", ".png", ".gif", ".bmp")): # rename file
I was wondering if there was any bash or powershell command in order to perform the above procedure.
