Tab-tab — Auto-suggest BONUS!
Bash comes with a special bonus: Tab-tab. When you hit tab twice, your shell prompt will show you a list of suggested completions and then return you to the same state ready to continue taking your input.
Remember, this might work in conjunction with #10 above, because your first tab may have completed the input to the point where your bash could make the completion. If there’s more than one option, bash will beep at you to let you know it couldn’t fully make your completion. Hit tab again, and you will see a list of matching filenames that are criteria for your completion.
