Bash / Shell Scripting: Command the Linux Terminal

Bash (Bourne Again Shell) is the default command-line shell on most Linux distributions. Shell scripting involves writing programs that the shell interprets — automating tasks, processing files, managing systems, and building tools that run directly from the command line.

Every Linux professional writes Bash scripts. Our books teach practical, production-quality scripting from basic one-liners to complex automation frameworks.
