Following the instructions here, I edited by .bash_profile to enable the up and down arrows to autocomplete what I have typed in the shell based on previous commands.
I added to my .bash_profile:
# bind history search to up and down arrows if [[ $- == *i* ]] then bind '"\e[A": history-search-backward' bind '"\e[B": history-search-forward' fi
This is great, but I want the down arrow to return to my original text if I can't find the command I'm looking for.
For example, say I have three previous commands:
Now, I type
ls with the intention of autocompleting it to
I hit the up arrow, which (with my current implementation) autocompletes my text to
ls -al. I hit the up arrow again, which autocompletes my text to
ls -l. At this point, I decide that I won't find the command I'm looking for. If I press the down arrow, the text changes to
ls -al, but pressing the down arrow again doesn't change anything. I want pressing the down arrow to return to my original text (
ls in this case) after I've reached the most recent command in the history.
I would really appreciate it if anyone could help me out or point me in the right direction.
