- nnn[0] (C) - A terminal file manager, similar to ranger. It allows you to navigate directories, manipulate files, analyze disk usage, and fuzzy open files.
- ncdu[1] (C) - ncurses disk analyzer. Similar to du -sh, but allows for directory navigation as well.
- z.lua[2] (Lua) - It's an alternative to the z utility mentioned in the article. I haven't done the benchmarks, but they claim to be faster than z. I'm mostly just including it because it's what I use.
