Bash Incremental History Search / Autocomplete
Published: 26-06-2013 | Author: Remy van Elst | Text only version of this article
❗ This post is over twelve years old. It may no longer be up to date. Opinions may have changed.
This little snippet for your .bashrc or your .inputrc changes the Up/Down arrow behavior to autocomplete what is already typed instead of just go back in history.
Normally when you press Up in Bash you get the previous command. With these
lines that is changed. If you typed vim filename, then top and then again
vim and pres up, it will autocomplete to vim filename instead of go back to
top.
Either in your .bashrc:
bind '"\e[A": history-search-backward'
bind '"\e[B": history-search-forward'
Or in your .inputrc:
"\e[A": history-search-backward
"\e[B": history-search-forward
