When the personal computer was young, a household was likely to have one (or fewer) computers in it. Children played games on it during the day, and parents did accounting or programming or roamed through a BBS in the evening.

Linux is famous for its commands. This is partially because nearly everything that Linux does can also be invoked from a terminal, but it's also that Linux as an operating system is highly modular. Its tools are designed to produce fairly specific results, and when you know a lot about a few commands, you can combine them in interesting ways for useful output.
