    A problem that plagued Unix in this period was the multitude of implementations, based on either System V, BSD, or what Poul-Henning Kamp later described as a "more or less competently executed" combination of the two, usually with home-grown extensions to the base systems from AT&T or Berkeley.

    A Unix shell is a command-line interpreter or shell that provides a command line user interface for Unix-like operating systems. The shell is both an interactive command language and a scripting language, and is used by the operating system to control the execution of the system using shell scripts. Users typically interact with a Unix shell using a terminal emulator; however, direct operation via serial hardware connections or Secure Shell are common for server systems. All Unix shells provide

    The most generic sense of the term shell means any program that users employ to type commands. A shell hides the details of the underlying operating system and manages the technical details of the operating system kernel interface, which is the lowest-level, or "inner-most" component of most operating systems. In Unix-like operating systems, users typically have many choices of command-line interpreters for interactive sessions. When a user logs into the system interactively, a shell program is

    The first Unix shell was the Thompson shell, sh, written by Ken Thompson at Bell Labs and distributed with Versions 1 through 6 of Unix, from 1971 to 1975. Though rudimentary by modern standards, it introduced many of the basic features common to all later Unix shells, including piping, simple control structures using if and goto, and filename wildcarding. Though not in current use, it is still available as part of some Ancient UNIX Systems. It was modeled after the Multics shell, developed in 1

    Variations on the Unix shell concept that don't derive from Bourne shell or C shell include the following: 1. es – A functional programming rc-compatible shell written in the mid-1990s. 2. Friendly interactive shell – First released in 2005. 3. PowerShell – An object-oriented shell developed originally for Windows OS and now available to macOS and Linux. 4. Qshell – A shell on the IBM i operating system based on POSIX and X/Open standards. 5. rc – The default shell on Plan 9 from ...
