Shell Script Basics Repository

Overview

Welcome to the Shell Script Basics repository! This project is designed to help beginners and intermediate users learn and practice shell scripting through a collection of well-documented scripts and examples. Whether you're automating tasks, managing system operations, or exploring DevOps workflows, this repository provides a solid foundation for mastering shell scripting.

Key Features

• Beginner-Friendly: Simple and easy-to-understand scripts for those new to shell scripting.
• Practical Examples: Real-world use cases, such as file management, system monitoring, and automation.
• Modular Design: Scripts are organized into categories for easy navigation and reuse.
• Comprehensive Documentation: Each script includes comments and explanations to help you understand its functionality.

Technologies and Tools Used

This repository leverages a variety of technologies and programming tools to ensure robust and efficient scripting:

• Bash (Bourne Again Shell): The primary scripting language used for all examples.
• Unix/Linux Commands: Core utilities like grep, awk, sed, find, and tar are extensively used.
• Automation Tools: Scripts integrate with tools like cron for scheduling tasks.
• Version Control: Managed with Git and hosted on GitHub for collaboration and version tracking.
• Testing Frameworks: Basic testing is performed using BATS (Bash Automated Testing System) for script validation.
• Text Processing: Advanced text manipulation using sed and awk for pattern matching and data extraction.
• System Monitoring: Scripts for monitoring CPU, memory, and disk usage using commands like top, free, and df.
• File Management: Examples include backup scripts, log rotation, and file synchronization using rsync and tar.
• APIs and Integration: Scripts demonstrate interaction with APIs (e.g., GitHub, Jira) using curl.

Getting Started

Prerequisites

• A Unix-based operating system (Linux, macOS, or WSL for Windows).
• Basic knowledge of terminal commands.
• Bash shell installed (default on most Unix systems).

Installation

1. Clone the repository:

   git clone https://github.com/waseemofficial/shell-script-basic.git
   cd shell-script-basic

2. Make scripts executable:

   chmod +x scripts/*.sh

Usage

• Backup Script: Automate file backups with compression.

  ./backups/backup.sh /path/to/source /path/to/destination

• System Monitoring: Monitor CPU and memory usage.

  ./monitoring/system-monitor.sh

• API Integration: Create GitHub issues from the command line.

  ./api-integration/github-issue.sh "Issue Title" "Issue Description"

🧑‍💻 Example Scripts

1. Backup Script

Automate file backups with compression.

#!/bin/bash
# backup.sh - Automates file backups
SOURCE=$1
DESTINATION=$2
TIMESTAMP=$(date +"%Y%m%d%H%M%S")
tar -czf "${DESTINATION}/backup_${TIMESTAMP}.tar.gz" "$SOURCE"
echo "Backup completed: ${DESTINATION}/backup_${TIMESTAMP}.tar.gz"

Usage:

./backups/backup.sh /path/to/source /path/to/destination

---

2. System Monitoring

Monitor CPU and memory usage.

#!/bin/bash
# system-monitor.sh - Monitors system resources
echo "CPU Usage: $(top -bn1 | grep load | awk '{printf "%.2f%%\n", $(NF-2)}')"
echo "Memory Usage: $(free -m | awk '/Mem:/ {printf "%.2f%%\n", $3/$2*100}')"

Usage:

./monitoring/system-monitor.sh

---

3. API Integration

Create GitHub issues from the command line.

#!/bin/bash
# github-issue.sh - Creates a GitHub issue
TITLE=$1
DESCRIPTION=$2
TOKEN="your_github_token"
REPO="your_username/your_repo"

curl -X POST -H "Authorization: token $TOKEN" \
     -d '{"title": "'"$TITLE"'", "body": "'"$DESCRIPTION"'"}' \
     "https://api.github.com/repos/$REPO/issues"

Usage:

./api-integration/github-issue.sh "Issue Title" "Issue Description"
