When I paste this and then source the file, I get:

-bash: \e[A:: command not found -bash: \e[B:: command not found

edit: thanks for the responses below. Learn something new every day :)

It goes in ~/.inputrc, the configuration file for GNU readline. Those aren't shell commands.

If you really want to put them in .bashrc instead of .inputrc, you can source readline directives with the 'bind' command, like so:

    bind '"\e[A": history-search-backward'   # up-arrow
    bind '"\e[B": history-search-forward'    # down-arrow

.inputrc. And don't source it, just start a new bash.

inputrc is not to be sourced; it's read by readline when the shell starts. You need to restart your shell.

CTRL-x-r will reload it as well, without having to restart your shell
