I have one and it’s very nice.

Many people get it, it is quite normal, I think. The trick to avoid is to practice mental hygiene - don’t let the shit come in. Ponder over things that you can influence, be a kind person and help others. That way you see the world in a better light and it’s good for your sleep. You won’t solve the problems of humankind anyway. And get out of industries that aren’t kind to the elder.

That’s why I included Perl, it is always there. Just don’t code as if you were in the nineties and Perl is a perfectly legitimate language, even more so for shell tasks. Bad and good doesn’t depend so much on the language but the coder.

Why not use Perl or python for scripting tasks? Bash script is terrible imo.

Fzf doesn’t need fish, though. I use it with bash.

Why do you assume, they had no such concern? There were seals to ensure authenticity and avoid man in the middle attacks. There were encoded messages, smoke, flags, light and sound signals. Trusted couriers, pigeons, etc …
