Describe your experience with using and administering Linux-based systems.

In my experience working with Linux, I have used this OS for both development and server administration. The main tasks included:

• Installing and configuring distributions (e.g., Ubuntu, CentOS).
• Managing users and permissions using commands like useradd, chmod, chown.
• Configuring network settings and services (SSH, firewall).
• Monitoring the system with top, htop, vmstat, dmesg.
• Automating tasks with Bash scripts.
• Managing packages with apt or yum.

For example, to set up automatic service startup, I used systemd:

sudo systemctl enable myservice
sudo systemctl start myservice

I also have experience debugging log issues in /var/log and configuring cron for periodic tasks.
