A really nice command-line trick is to enable history autocomplete via up and down arrows. For example, if I am looking for an old ‘grep’ command, I could cycle through all greps in my history simply by typing ‘grep’ UP-ARROW.
All you need to do is add the following lines to the ‘.profile’ file in your home directory.
# make bash autocomplete with up arrow/down arrow bind '"\e[A":history-search-backward' bind '"\e[B":history-search-forward'
Note – You’ll need to start a new terminal session for this to take effect.
