What is Shell Scripting?
Shell scripting refers to writing scripts or programs in a shell (command-line interface) to automate and execute a series of commands and tasks. The shell is a program that provides an interface for users to interact with the operating system.
In Linux and Unix-based systems, the most commonly used shell is the Bash (Bourne-Again SHell) shell. Shell scripts are written using various programming constructs like loops, conditional statements, variables, and functions to perform a wide range of tasks, from simple file operations to complex system administration tasks.
Shell scripts can be used to automate repetitive tasks, batch processing of files, system maintenance, backup and restore, monitoring, and many more. Shell scripting is an essential skill for system administrators, developers, and power users who work with the command-line interface on a regular basis.
