In short, a heck ton of them. I can write a series of articles about which tools I use. I made it a credo to gather as much as possible CLI and TUI tools and become master at them. The latter part still eludes me – not enough time and energy still – but I have become quite the small encyclopaedia of CLI/TUI tools.
Waiting for Aston’s “you should write a blog about it Dimi!”.
