Linux shell command shortcuts

Handy forgotten shortcuts, for those lazy moments;

• UP Arrow - Previous command.
• TAB - Autocomplete.
• history - Displays command history.
• !! - Execute previous command (I don't like, prefer UP ARROW).
• !n - Executes the command n in the history.
• !$ - Recall argument used on the previous command (if there was one).
• ALT . - Filter through previous arguments (doesn't always work, especially on Mac).
• ^r (CTRL r) - search through history.
