Does anyone have a script for lossless image compression on the server?

Question

linux

We need a script so that we can specify the directory in which we search and compress via jpegoptim, jpegtran, pngcrush, optipng, advpng, gifsicle or others, if something new has appeared.
We search in the directory and subdirectories.
Saving originals is optional.
It should work on Centos from the command line.
From what I found:

stackoverflow.com/questions/19153122/image-compres...
sharadchhetri.com/2014/05/29/jpeg- image-optimizati...
But it's not clear how to force search and process images in the directory and subdirectories

Answer 1

script and no one in general KNOWS whether the image is compressed or not

Answer 2

How to reduce thousands of pictures in all subfolders?

Answer 3
