This article briefly examines and compares the kernels of the three most widely used quasi-Unix operating systems using three axes of comparison: efficiency, evolvement, and user friendliness. The ...

The OS allows for paging, multitasking, a file system, and exception handling. It doesn’t implement interrupt handling, timers, inter-process communication, or handling of multiple processors.

As [Bruno Croci] found while digging into this question, it is not the shell that interprets the shebang, but the kernel.

Linux is a tried-and-true, open-source operating system released in 1991 for computers, but its use has expanded to underpin systems for cars, phones, web servers and, more recently, networking gear.
