Bash

Use an edition interface in line vim style in your bash shell, just include the following opcion in your ~/.bashrc file:

set -o vi

Bonus: If you want to show the current mode, which is really convenient, try including the following code in your /etc/inputrc file:

set show-mode-in-prompt on
set vi-cmd-mode-string "|c|"
set vi-ins-mode-string "|i|"

The result will look something like this:

|i|user@machine:~$ Hello wo

Vim

Vim is a highly configurable text editor built to make creating and changing any kind of text very efficient. The way that you interact with it make it more than just a text editor (or not), a way of interacting with your entire computer.

• Tools where I currently use Vim keybindings:
  • aerc: an email client that runs in the terminal, highly efficient and extensible
  • bash: the GNU Project’s shell the Bourne Again SHell
  • dwm: dynamic window manager for X
  • qutebrowser: a keyboard-focused browser with a minimal GUI
  • tmux: a terminal multiplexer
  • vifm: a file manager with curses interface, which provides Vim-like environment for managing objects within file systems, extended with some useful ideas from mutt
  • pulsemixer: cli and curses mixer for PulseAudio

You can find a comprehensive list of applications using Vim keybindings in the The Keybindings Everywhere - The Ultimate List.

• Tools I’ve used but I stop using or rarely use
  • NeoMutt: a command line mail reader
  • bspwm: tiling window manager (binary space partition window manager)
  • i3: improved tiling window manager
  • vidir: edit directories and filename in vim (or other text editor, if you find a reason for that …)
