Bash
Bash (Bourne Again SHell) is a Unix shell and command language used primarily in Linux and macOS environments. It provides a command-line interface for interacting with the operating system and allows users to write scripts to automate tasks, manage files, and execute programs. Bash scripting combines shell commands with programming constructs like variables, loops, and conditionals to create reusable automation workflows.
Developers should learn Bash for system administration, DevOps, and automation tasks, such as deploying applications, managing servers, or processing log files. It is essential for working in Unix-like environments, including cloud infrastructure and CI/CD pipelines, where shell scripts are commonly used to configure environments and run build processes. Bash skills are also valuable for local development automation, like setting up project environments or batch-processing data.
