Ble.sh seems pretty cool. The path hacking it does on readlink doesn't work right and causes the CNF handler to launch on NixOS.

I guess it does the PATH hacking based on whether the system is GNU or not so that it can get `realpath`/`readlink -f`-like behavior even on systems that don't natively have that because they include *BSD coreutils.

That might not behave as expected (and is unnecessary) on my macOS systems, either, since I like to keep GNU coreutils (with no `g` prefixes on the executable names) on my PATH there (heresy, I know).

It's also noticeably slower, to the point that there's a bit of jitter as I type.

It's pretty cool, though. If it's any better after I patch the readlink PATH hacking out, maybe I'll configure it for bash on my systems.

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.

That's weird. Fish has all of the GNU readline shortcuts OOTB and has for as long as I can remember
