Shell programming

Shell programming involves writing scripts for the command-line interface of an operating system like Linux or macOS. These scripts automate tasks such as file management, system monitoring, and software execution by issuing a sequence of commands. Think of it as creating a set of instructions that the computer can run automatically, saving time and reducing manual effort. Shell scripts help users customize workflows, manage system resources efficiently, and perform repetitive tasks reliably. They are fundamental for system administrators, developers, and advanced users to streamline operations and maintain control over complex computing environments.
