What is Shell?

1.	What is Shell?
Answer» A Shell is basically a command-line interpreter between user and kernel or a complete ENVIRONMENT specially designed to run COMMANDS, shell scripts, and programs. In this, whenever a user enters human-readable commands (input commands) through the keyboard, the shell communicates with the kernel to execute these commands, and DISPLAY output in a shell script. Just as there are different flavors of operating systems, there are also different types of shells. Every shell has its own set of commands and functions. Shells ISSUE the prompt, $, called a command prompt. You can type into the prompt while it is displayed. After you press enter, your input is read by the shell. Based on the first word of your input, it determines the command you want to run. The characters in a word are separated using spaces and tabs. Example: Here is an example of a date command that displays the current date and time: $date Tue Aug 10 06:03:35 MST 2021
