Here's a cool way to do OCR of any area of your screen and copy the result directly to you clipboard:
import png:- | tesseract stdin stdout | xclip -i -selection clipboardYou need tesseract and imagemagick. This works on systems using the X windows system. There's another way to do it in Wayland.
Do those come standard in Red Hat Linux 8?
Probably not, but can be installed from the default official repos.
