A simple Bash script that performs a complete system update and cleanup on Debian-based systems.

• Updates package lists (apt-get update)
• Upgrades all installed packages (apt-get upgrade)
• Performs distribution upgrade for better dependency handling (apt-get dist-upgrade)
• Removes unused/orphaned packages (apt-get autoremove)
• Cleans up apt cache (apt-get autoclean)
• Logs all operations with timestamps to /var/log/system-update.log

1. Make the script executable:

chmod +x debian_maintenance_script.sh

2. Run with sudo (root privileges required):

sudo ./debian_maintenance_script.sh

All operations are logged to:

/var/log/system-update.log

Each run is timestamped for easy tracking.

To run this script automatically, add it to your crontab:

sudo crontab -e

Example: Run every Sunday at 3 AM:

0 3 * * 0 /path/to/debian_maintenance_script.sh

• Debian-based system (Debian, Ubuntu, Linux Mint, etc.)
• Root/sudo privileges
• Bash shell

• This script runs with -y flag, meaning it will auto-confirm all prompts
• Review the log file after execution to check for any issues
• Consider testing on a non-production system first
