K&R book is great! When you’re done with that I highly recommend you move on to “Modern C” by Jens Gustedt. It’s available for free online or in print. Brought my C knowledge up to date with all the cool stuff C23 has in it. Jens’ blog is a great resource as well.

Aside from the automation, which has been mentioned already, I tend to seek out terminal based solutions and heavily use it over GUIs because:

• my wrists tend to hurt after using a mouse for too long (mouse use is now limited mostly to browsing the web and spreadsheets)
• lower resource footprint means I can do more with less hardware
