What are your favorite non-standard CLI/TUI applications?
I use “non-standard” loosely here. I’m looking for CLI utilities that are definitely not part of the POSIX required or optional utilities, and more colloquially not considered to be standard BSD or *nix fare.
fzf, ncdu, sd (sed alternative), fd (find alternative)
ripgrep
GNU datamash - handy for field processing like collapse, sum, etc (instead of awk/perl)
