computer nonsense, regexes, arcane computer magic
Much of my early coding was in Perl, so I have been writing regular expressions for well over a decade now, and as a result am very good at reading and writing them. None of that means they feel one bit less like arcane magic.
This brought to you by my quick and dirty snake-case to CamelCase conversion:
perl -p -e 's/\b-?(\w)/\U\1/g'
Like, it works and I can parse it out but is sure is impenetrable at first glance for such a simple transformation!

@cincodenada now I'm thinking of how I'd do this for readability! split, cap, join I guess?

Also, disclaimers: this is for a very limited-scope one-off bash kludge, I do not care how robust it is, and also please never do this in any context where someone else might have to read your code. I guarantee there's a built-in or readily-available library method in practically every language to do this. Heck, there might be a standard bash util I'm not aware of!
