Command Line

An ever-chaning collection of command line tools that I find useful on a daily basis or just fun to play with from time to time.

Command Line

While I do have a strong preference for single a.out binaries without large dependency trees that do not require additional runtimes, I’m also a strong believer of using the right technology for the right job. Hence, I obviously prefer C/C++, Rust, and Go programs, but I also don’t mind using Python-, Node.js-, Ruby- or Elixir/Erlang-based helpers to get a job done. For example, I would definitely want a C/C++ or Rust alternative to ls – glad you’re asking, have eza please and thank you – over a Node.js version, simply because I want it to be instantly available and chew up as little CPU and memory as possible. That’s also one of the reasons I try to stay at least 6 feet apart from everything Electron-based, and why I don’t touch anything that requires the JVM even with a 10 foot pole.

The Environment

I’m using Alacritty with a
minimalist config, the Z shell with Oh My Zsh and a rather large .zshrc. I sometimes use tmux.

My color schemes change from time to time, but you can check my dotfiles to see what I’m currently using.
