Answer a question

I have many webp format images in a folder but with .jpg extension like

abc-test.jpg

It's a webp format image. I want it to convert in .png format with same name for that I have used this command and it worked

find . -name "*.jpg" -exec dwebp {} -o {}.png \;

It converted all webp images to .png but the issue is it's saving images like this:

abc-test.jpg.png

But my requirement is to save it without .jpg extension like

abc-test.png

If you have many to convert/rename, I would recommend you use GNU Parallel and not only get them converted faster by doing them I parallel, but also take advantage of the ability to modify filenames.

The command you want is:

parallel dwebp {} -o {.}.png ::: *.jpg

where the {.} means "the filename without the original extension".

If you want to recurse into subdirectories too, you can use:

find . -name "*.jpg" -print0 | parallel -0 dwebp {} -o {.}.png

If you want a progress meter, or an "estimated time of arrival", you can add --progress or --eta after the parallel command.

If you want to see what GNU Parallel would run, without actually running anything, add --dry-run.

I commend GNU Parallel to you in this age where CPUs are getting "fatter" (more cores) rather than faster.
