CLI: Improved
GNU Parallel is the first thing I usually install on top of a standard Unix userland. It&#x27;s almost a superset of xargs, with many interesting features. It depends on perl, though.<p>htop is also pretty much a great replacement for top. And ripgrep a great replacement for the find | xargs grep pattern.<p>Aside from that, I&#x27;m pretty content with the Unix userland. It&#x27;s remarkable how well tools have aged, thanks to being composable: doing one thing and communicating via plain text.<p>I&#x27;m less happy with the modern CLI-ncurses userland. Tools like e.g. mutt are little silos and don&#x27;t compose that well. I&#x27;ve migrated to emacs, where the userland is much more composable.
