Shell Scripts
Shell scripts are text files containing sequences of commands for Unix-like operating system shells (e.g., Bash, Zsh) that automate tasks, manage system operations, and process data. They are interpreted by a shell program, allowing developers to combine command-line utilities, control flow, and variables into reusable scripts. Common uses include file manipulation, system administration, deployment automation, and batch processing.
Developers should learn shell scripting to automate repetitive tasks, streamline workflows, and enhance productivity in development and operations (DevOps). It is essential for system administration, server management, and CI/CD pipelines, where tasks like log analysis, backup automation, and environment setup are frequent. Shell scripts are particularly valuable in Unix/Linux environments for quick prototyping and integrating command-line tools.
