Firstly, why is =~ completely undocumented in the bash man page? This question was my first encounter with the feature.
Because it's not --- not undocumented, that is. Manpage search can't seem to find it, but it _is_ there.
Just search for '==' instead, then go one paragraph down.
Secondly, why does quoting the expression invalidate it?
I suspect that's because the manual actually says it does. As I'm reading it, they're (ab)using quotation to mean "this is not meant to be a regex, but rather a straight text search pattern"
