A Useful Thing in Bash

GNU Readline, for those who doesn't know, also comes with vi mode, where you can search with '/' and '?' keys. You can enable it with 'set -o vi' in bash shell or putting 'set editing-mode vi' it in ~/.inputrc.

If you put it in ~/.inputrc, you will get vi mode in all tools/shells which are using Readline like mysql, rlwrap, psql...

If using readline in vi-mode, I recommend also setting `set show-mode-in-prompt on` to provide visual feedback on which mode you're in. Maybe it's just me, but sometimes I walk away from a repl for quite a while (weeks sometimes) and when I come back to it I stumble for a moment because it wasn't in the mode I was expecting.

Agreed, I just wish it could be a bit more customisable. like so https://savannah.gnu.org/support/?109610

It's completely customizable! Just takes some creativity.

vi command line editing mode is required by POSIX (see under EXTENDED DESCRIPTION at https://pubs.opengroup.org/onlinepubs/9699919799.2018edition...)
