🧑‍💻 Overview

Shell scripting is a powerful way to automate tasks, manage systems, and interact with Unix/Linux operating systems. It combines the simplicity of command-line utilities with the flexibility of programming logic, allowing users to automate repetitive tasks, manage system operations, and perform complex operations with minimal manual intervention.

This repository contains examples of shell scripts that demonstrate key concepts such as process management, file handling, task automation, and system monitoring.

✨ Features

This repository includes practical shell scripting examples that demonstrate:

• Basic Shell Commands: Common commands like ls, pwd, cd, cp, mv, and rm.
• Variables and Parameters: Using variables and accepting parameters in shell scripts.
• Control Structures: Conditional statements like if, else, and loops such as for, while, and until.
• File Handling: Working with files and directories, reading and writing data, and checking file statuses.
• Process Management: Handling background and foreground processes, and using ps, kill, and jobs.
• Text Processing: Using grep, sed, awk, and cut to process text data efficiently.
• Task Scheduling: Automating tasks using cron and at.
• System Monitoring: Scripts to monitor CPU, memory, disk usage, and network activity.
• Error Handling: Incorporating error handling and debugging techniques in shell scripts.

🚀 Getting Started

Prerequisites

Before running the scripts, ensure you have access to a Unix-like operating system (Linux, macOS, etc.) and a shell environment like bash, sh, or zsh. You can check your shell version by running:

echo $SHELL
