Linux Shells and Shell Programming (Bash)

Shell Programming is also known as Shell Script is a program that runs on the Shell commands. It consists of one or more shell commands which are created using the text editor based on the user’s choice. These shell programs are executed just like shell commands which have permission modes and should have the correct set of permissions to execute a program.
A Shell provides you with an interface to the Unix system. It gathers input from you and executes programs based on that input. When a program finishes executing, it displays that program's output.

Shell is an environment in which we can run our commands, programs, and shell scripts. There are different flavors of a shell, just as there are different flavors of operating systems. Each flavor of shell has its own set of recognized commands and functions.
