$0 is the name of the running process. If you use it inside of a shell then it will return the name of the shell. If you use it inside of a script, it will be the name of the script.

- Anil Harwani told us about the Tanenbaum-Torvalds debate on OTC CatchUp #145, which was an argument where Tanenbaum was trying to prove why a Microkernel architecture (Tanenbaum's OS Minix had that architecture.) is better than a Monolithic Kernel architecture that Torvald's Linux has.
- Kernel architectures
- Minix
- Tanenbaum initially created the Minix Operating System for educational purposes.
- Anil also told us how Minix was found inside the Intel Management Engine, which was a big deal, as Minix, whose goal was never to have military-grade security, was being used on billions of machines at a privilege level that is higher than the kernel, and that made billions of machines vulnerable. Also, this implies that Minix is the most used OS on the planet.
