"Is it just about having minimal boilerplate"

That's a lot of it, but I think people don't realize how every keystroke counts with shell.

There's only a handful of languages where the "apply function" operator is space. Shell is one of them. (Haskell & Forth are the other two I know off the top of my head, possibly Factor (concatenative in general tends this way).) Most new shells that are successful copy this. I don't think that's a coincidence. Lisp's abundance of parens is something that people will have trouble with, even Lisp programmers, because this is not the usual whining about a foreign language paradigm and not being used to reading parens... this is literally about the effort required to physically enter them with a keyboard.
