What makes me an expert is the amount of computer books I have near my desk. Sort of like how the enchantment table works in Minecraft. I am also a bash expert because I own an O’Reilly book on the subject I bought at a Borders 20 years ago at retail price. :)
I am a bash expert as well then, and probably the only person insane enough to have a web framework, complete with http server written in bash.
I'd say you were both masochistic and way beyond just being an expert in that case.
Bash Technical Fellow?
10 years ago my colleagues were astounded by my airtight bash scripts which formed the backbone of our deployment pipeline. I've come a long way since then, and I still learn new things about it regularly, so I guess I'm a bash expert.
