Shell scripting is a powerful tool used in the world of computing to automate tasks and streamline processes within a Unix-like operating system. Essentially, it involves writing a series of commands in a text file that the operating system's shell interpreter can execute sequentially. These scripts can range from simple tasks like file manipulation to complex system administration tasks. Shell scripting provides a flexible and efficient way to handle repetitive tasks, allowing users to save time and effort by automating routine operations. Additionally, it offers great versatility as it can interact with system utilities, external programs, and even other scripts, making it an essential skill for system administrators, developers, and power users alike.
