Shell Scripting

Shell scripting is a powerful tool in the Linux environment that allows for the automation of tasks through scripts, which are programs executed within a shell (command-line interpreter).

Understanding Shell Scripts

A shell script is a text file containing a series of commands executed by the shell. Shell scripts are versatile, allowing anything that can be executed in the terminal to be automated through a script.
Shell scripts streamline workflows by automating repetitive tasks. They are essential for efficient system management, task scheduling, and complex command sequences.

Debugging Your Shell Scripts

Debugging is a critical skill in programming, essential for identifying and fixing errors or "bugs" in code.

Bugs in Shell Scripts: Bugs can manifest as syntax errors, logical errors leading to incorrect outcomes, or runtime errors causing scripts to fail unexpectedly.
Debugging Process: Debugging involves systematically examining script execution to identify why and where the script deviates from expected behavior. The goal is to pinpoint errors and apply fixes.
