What modern tools should be standard part of a modern unixy distro?Why?

https://github.com/kellyjonbrazil/jc which can parse output of various command-line tools into JSON. And jq (https://stedolan.github.io/jq/) of course.

I've been consistently surprised basic utilities (netstat, iostat, screen (or tmux), etc etc) are NOT by-default installed on servers with a 'vanilla' instal (ie not requiring an extra kickstart or autoyast)

jq/fq - for working with json/binary formats

csvkit/miller - for working with csv, tsvs

rg/fzf - for search and fuzzy finding

There are many tools like lsd, bat, fd and a few more.
