Bash Scripting Practice

A hands-on repository documenting my learning journey in Bash scripting, Linux commands, log analysis, and system administration automation.

Topics Covered

• Bash variables, arrays, loops, and conditional statements
• Linux commands: find, grep, cat, and chmod
• Log analysis and severity-based filtering
• Error counting and threshold-based warnings
• Practical shell scripting and automation

Projects

Log Analysis Script

File: 03-log-analysis/analyse_logs.sh

A Bash script that:

• Finds recently modified log files
• Searches for ERROR, FATAL, and CRITICAL messages
• Displays matching log entries and counts
• Warns when a severity count exceeds a configured threshold

How to Run

chmod +x 03-log-analysis/analyse_logs.sh
./03-log-analysis/analyse_logs.sh

Update the log directory in the script to match your local environment.

Progress

This repository will grow as I practice new Bash commands and build practical automation scripts.
