Linux System Administration

Linux runs most production servers, cloud platforms, and infrastructure, and administering it well is a command-line skill. This Specialization takes you from your first terminal command to managing users, automating tasks, and securing a live system, working the way administration is actually done in practice. By the end of this Specialization, you will be able to: Navigate the Linux filesystem and run core commands using pipes, redirection, and text-processing tools such as grep, sed, and awk. Administer users, groups, and sudo privileges, and manage processes and services with systemd on a live Linux system. Write Bash scripts with variables, loops, and functions, and automate scheduled tasks with cron. Configure networking, diagnose connectivity, harden SSH, and secure systems with firewalls and intrusion prevention. This Specialization is designed for beginners and career starters who want practical Linux skills, aspiring system administrators and DevOps engineers, IT support professionals moving into server administration, and developers who want to work confidently on the command line. No prior Linux experience is required; comfort using a computer and a willingness to work in a terminal is enough. Command-line proficiency, scripting, and system security are foundational requirements across IT, DevOps, and cloud roles, and across the cloud platforms that run on Linux.
