Unix Shell
Unix Shell is a command-line interface and scripting language that serves as the primary user environment in Unix-like operating systems, such as Linux and macOS. It interprets user commands to interact with the operating system kernel, manage files, run programs, and automate tasks through shell scripts. Common shells include Bash, Zsh, and Korn Shell, each offering features for system administration, development, and automation.
Developers should learn Unix Shell for system administration, automation, and efficient command-line workflows, especially in DevOps, backend development, and data processing. It is essential for tasks like file manipulation, process management, and scripting repetitive operations, making it a core skill for working with servers, containers, and cloud environments. Mastery improves productivity in environments like Linux servers, CI/CD pipelines, and data analysis tools.
