What should beginners learn BEFORE nmap — terminal, networking, or neither?

Curious what people actually recommend.

I keep seeing new learners jump straight to `nmap -A` and then:

– not knowing where their output file went

– not knowing how to `grep` open ports

– not knowing what `ss -tuln` is showing

– not knowing localhost vs a real target

I made a short flash-card "Beginner Lab Atlas" (56 commands) that covers files,

filters, pipes, DNS, and listening ports — intentionally before any nmap flags.

Is that the right order, or do you throw people into scanning day one?

Lab only: localhost / authorized targets.
