My favorite use of cat is hiding malware in images and gifs. Don’t worry, I’ve never actually deployed any malware over social media, I just know how to use cat (and a few other things) to do it.
Some image formats will ignore junk data after the image. So you can probably run cat image.png message.txt to embed text in image files, although I haven’t tried this myself.
Dude, people still think vi is important skills. I know ‘ed’, so the rest is just a waste.
For that matter, just use cat, and be free of vietnam-era cult shit.
