6 Bash Productivity Tips

1. Use !!
Typing !! followed by Enter will bring back and execute the last command (same as Ctrl+P followed by Enter).

2. Use Emacs-like shortcuts
Emacs-like shortcuts make use of the Ctrl and Alt keys, and the big advantage of navigating and manipulating text in a Bash prompt is that you won't have to move your fingers away from the typing position (to access the arrow keys, or the Home, Page Up and Page Down keys). Notice that most of those work well inside manual pages too, or when using the Nano editor, or the less and more pagers.
