I find it amusing when people are discussing all these new shells and features, yet everytime I see someone letting them know they can do these exact same things in bash, there's absolute silence. It's not the first time I see ble.sh being recommended here with no reactions from the community whatsoever. As for fish, I've used it for a few weeks. Not having POSIX compatibility and GNU readline shortcuts made work much, much harder.
