A small project showcasing my learning journey with Bash scripting.
I built scripts to analyse log files (system.log and application.log), applying variables, loops, conditions, and arrays, while experimenting with aesthetic output formatting.

📖 What I Learned

From the video and through practicing, I gained experience with:

• Fundamental Bash scripting concepts: variables, arrays, conditionals (if-else), loops (for, while).
• Parsing log files (e.g. system.log, application.log) to extract useful information.
• Using standard Unix tools for text processing: grep, awk, sed, cut, etc.
• Building scripts that automatically analyze logs (counting errors, extracting recent entries, summarizing statistics).
• Formatting output for readability: separators, headings, possibly colors or emphasis.

🛠 Project Features

This project implements:

• Script(s) to analyze system.log and application.log
• Counting number of error or warning messages
• Retrieving the most recent error or critical log entry
• Aggregating statistics (which module generates most errors, etc.)
• Neat output: headings, sections, clean alignment

🚀 How to Use

1. Clone the repository

git clone https://github.com/surojitmahanta/bash-log-analysis.git

cd bash-log-analysis

Make the script executable

chmod +x analyse_logs.sh

Run the script

./analyse_logs.sh

View the output in the terminal. You should see sections like “Application Log Analysis”, “System Log Analysis”, counts of errors/warnings, most recent entries, etc.
