What is the difference between the Bourne shell and the C shell?

The Bourne shell (sh) and the C shell (csh) are two different command line interpreters.

The Bourne shell is the original Unix shell created by Stephen Bourne. It is a command line interpreter that processes commands and executes programs. It is used for writing shell scripts, which are a set of commands that can be executed as a single program. The Bourne shell is best for writing complex shell scripts and is the default shell for most Unix-like systems.

The C shell (csh) was created by Bill Joy in the late 1970s. It is a command line interpreter that provides an interactive environment for users to type commands. It is best for everyday interactive use and is the default shell for BSD-based systems. The C shell provides features such as history, aliases, job control, and command line editing.

Example:

Bourne Shell:

$ echo “Hello World”
Hello World

C Shell:

% echo “Hello World”
Hello World

A terminal is a physical device that provides access to the command line interface of a computer system, while a shell is a software program that provides an interface for users to interact with the operating system.

For example, a physical terminal might be a monitor and keyboard connected to a server, while a shell might be a program like Bash or Zsh that interprets commands from the terminal.
