These short bash commands or code snippets have proven useful. I will try to collect them here, and maybe freeze some of them into a proper .bashrc (and the relevant equivalent on Windows). Alternatively, I could bundle related snippets into blog posts. Let's see where this goes.

Bash mkdir export && magick mogrify -resize 3000×3000 -quality 80 -path export *.jpg

PowerShell mkdir export; magick mogrify -resize 3000×3000 -quality 80 -path export *.jpg
