๐Ÿ–ผ๏ธ โžบ

An operating system shell is a computer program that provides relatively broad and direct access to the system on which it runs. The term shell refers to how it is a relatively thin layer around an operating system.12

Most shells are command-line interface (CLI) programs. Some graphical user interfaces (GUI) also include shells.

Footnotes

  1. โ€œThe Internetโ€™s fifth manโ€, Brain scan, The Economist, London: Economist Group, December 13, 2013, Mr Pouzin created a program called RUNCOM that helped users automate tedious and repetitive commands. That program, which he described as a โ€œshellโ€ around the computerโ€™s whirring innards, gave inspirationโ€”and a nameโ€”to an entire class of software tools, called command-line shells, that still lurk below the surface of modern operating systems. โ†ฉ
