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.
