Nice slides. I missed him covering ripgrep and friends, which is very useful to avoid slower find-grep queries. Along with ripgrep, I think GNU Parallel (covered in the slides) and htop (briefly discussed) are great additions to any Unix development environment. The rest of the standard utilities have stood the test of time surprisingly well. But top is a bit wonky, xargs has many pitfalls and, as I said, ripgrep is…
Also, I recommend using fd as a replacement for find. It’s API is a bit easier to grok imo, and it’s similarly blazing fast.
fd/rg/fzf are the core tools I end up using most frequently, working in a big monorepo.
