Biomechanics & Muscle Memory Tips
- 1Command-line speed relies heavily on double hyphens (--) and forward slashes (/)—avoid looking down when typing flags.
- 2Drill pipe (|) and redirection (>, >>) strokes with opposite-hand Shift alternation for effortless bash chaining.
- 3Keep your right pinky anchored near J/K/L/; rather than floating off the keyboard between terminal arguments.
