Most common bash/zsh syntax works in shell. For most day to day shell usage, I'd say: * get comfortable with stdin/stdout/stderr syntax (and redirection) * get piping down pat. It's so useful. * practice using &&, ||, and ; to sequence commands * know how to use ENV=value to override env vars, and understand how env vars work * yak shave a bit and make some aliases/functions in your shell based on your usage patterns From here, it gets esoteric pretty fast, no matter what shell you're in. But you have enough concepts to figure out you need from there.
