People have been rewriting and improving misc unix cli tools with better, prettier, faster, more convenient apis, plus speed.
It'd be fun to write one of these!
On my list:
fd is wonderful. Some other "better in rust" utilities: https://github.com/ogham/exa - ls replacement with color, better human defaults https://github.com/Byron/dua-cli - du replacement https://htop.dev/ - top replacement https://github.com/sharkdp/bat - cat replacement w/ syntax highlighting, git status, line numbers https://github.com/BurntSushi/ripgrep - grep replacement :man-running: https://github.com/dalance/procs - ps replacement https://github.com/ducaale/xh - httpie replacement https://github.com/emacs-mirror/emacs - vim / vscode replacement
