I’ll start:
- Tmux
- vim
- ghidra
- okteta (hex editor)
- speedcrunch (calculator with bit manipulation)
- python3 with IPython for nice reply and embed(), pwntools
- alacritty
- neovim
- tmux
- vifm - terminal file manager with vi keybindings.
- zathura - pdf reader with vi keybindings.
- inxi - prints information about your hardware.
- tldr - cheat sheet for common commands
- qalculate - the most powerful calculator I’ve seen. There are qt, gtk and cli versions of it.
- moreutils - collection of tools. My favourite is vidir, it opens directory structure in your terminal text editor, so that you can rename multiple files easily.
