Down and dirty in unix...

Long ago, I used assembly language for the PC (in DOS) every day.

These days, working with microcontrollers, I only dip into assembly when debugging or writing initilization code.

But assembly is far from dead. Even for the PC.

Even for OSes like UNIX.

Yup. While Unix was written in C to be portable, you can get "down and dirty" if you want.

The interface is via (for a PC-based system) INT 80h, which also happens to be the website which teaches an introduction to assembly and UNIX on the PC.
