5. System Monitoring and Performance Tuning: Monitoring system resources, such as CPU, memory, disk usage, and network activity. Optimizing system performance and troubleshooting performance issues.

6. Network Configuration: Configuring network interfaces, setting up IP addresses, managing network services (e.g., DNS, DHCP), and troubleshooting network connectivity.

7. Security and Firewall Configuration: Implementing security measures, configuring firewalls (e.g., iptables), managing user access controls, and ensuring system and data integrity.

8. Backup and Recovery: Setting up and managing backup solutions to protect critical data and implementing recovery procedures in case of system failures or data loss.

9. Shell Scripting and Automation: Writing shell scripts (e.g., Bash, Python) to automate repetitive tasks, streamline system administration, and improve efficiency.

10. System Updates and Patch Management: Applying software updates, security patches, and system upgrades to keep the Linux system up-to-date and secure.

11. Troubleshooting and Problem Resolution: Identifying and resolving system-related issues, diagnosing hardware or software failures, and implementing appropriate solutions.
