Open Source Software Audit - Git

Student Name: Pradyumn Krishna Arya
Roll Number: 24bai10668
Course Name: Open Source Software
Chosen Software: Git

Project Overview

This project is an audit and exploration of Git, the world's most popular distributed version control system. It demonstrates a practical understanding of Git's open-source nature (licensed under GPL v2) and its footprint on a Linux environment. The repository includes a set of Bash shell scripts to audit the system, inspect FOSS packages, analyze logs, and dynamically generate an open-source manifesto.

Included Shell Scripts

1. System Identity Report (script1_system_identity.sh)

Displays the current Linux distribution in use, kernel version, logged-in user details, and system uptime. It includes a brief note about Linux's GPL licensing.

2. FOSS Package Inspector (script2_package_inspector.sh)

Checks if Git is installed on the system using dpkg/apt or which. It displays the installed version and gives a quick overview of Git's purpose and its primary license.

3. Disk and Permission Auditor (script3_disk_auditor.sh)

Loops over crucial Linux directories (like /etc, /var/log, /home) to report their size and permissions. It also checks if the global Git config (~/.gitconfig) exists.

4. Log File Analyzer (script4_log_analyzer.sh)

A utility script that reads any log file line-by-line. Provide a log file and optionally a keyword (defaults to "error"). It returns the number of matches and the last few matching lines.

5. Open Source Manifesto Generator (script5_manifesto_generator.sh)

An interactive script. It asks you a few simple questions about your tech interests and generates a customized text file (manifesto_<username>.txt) detailing your personal open-source philosophy.

How to Run the Scripts on Ubuntu/Linux

Step 1: Make scripts executable Before running any script for the first time, you must give it execute permissions:

chmod +x script*.sh

Step 2: Execute the scripts Run each script using ./:

./script1_system_identity.sh
./script2_package_inspector.sh
./script3_disk_auditor.sh
./script4_log_analyzer.sh /var/log/dpkg.log
./script5_manifesto_generator.sh

Dependencies

• A standard Linux environment (Ubuntu/Debian recommended)
• Bash shell
• Standard pre-installed utilities: awk, du, grep, dpkg (for Debian-based distros)
