This is a repost from https://coderwall.com/p/oqtj8w but it’s so handy, I want to share anyway :-)
Create ~/.inputrc and fill it with this:
"\e[A": history-search-backward "\e[B": history-search-forward set show-all-if-ambiguous on set completion-ignore-case on
This allows you to search through your history using the up and down arrows … i.e. type “cd /” and press the up arrow and you’ll search through everything in your history that starts with “cd /”.
