resizeComics.sh

sh image_processing/resizeComics.sh file1.cbz file2.cbz ...

Batch processes CBZ comic archive files: extracts images, resizes them to 70% of original dimensions at quality 70 using ImageMagick, then recompresses into CBZ. Processing is parallelized with GNU parallel.

screenshots.sh

sh image_processing/screenshots.sh

Captures a screenshot every 4 hours on Linux (using scrot) and saves it to ~/Dropbox/Screenshots/ubuntu/. Useful for keeping a visual log during long-running tasks. Runs indefinitely until interrupted.
