Why Linux Matters in Engineering
Linux powers most cloud servers, Kubernetes nodes, container runtimes, CI agents, and observability stacks. If you can diagnose Linux quickly, you reduce MTTR across almost every platform team workflow.
Linux - Zero to Hero
Learn Linux from fundamentals to production operations: filesystem, users, packages, processes, networking, systemd, security hardening, performance tuning, and real incident troubleshooting.

What You Will Build
This track gives you practical Linux admin capability: secure host setup, day-2 operations, process and network diagnostics, service recovery, and a reliable incident response checklist.
Basics
Build Linux foundations: OS concepts, directory structure, permissions, users/groups, and package management workflows.
What is Linux and Why It Matters
Core concepts, distributions, and production relevance for cloud and DevOps teams.
Lesson 1
Linux Filesystem and Directory Structure
Understand /etc, /var, /home, /usr, /tmp and operational troubleshooting paths.
Lesson 2
File Permissions, Users, and Groups
Ownership and permissions with chmod, chown, sudo, and least privilege strategy.
Lesson 3
Package Management on Linux
Install and update software safely with apt and dnf in enterprise environments.
Lesson 4
Intermediate
Operate Linux in production with process control, network diagnostics, services, logs, and Bash automation.
Process Management and System Monitoring
Use ps, top, htop, vmstat, and free to diagnose runtime stress quickly.
Lesson 5
Networking Basics for Linux Admins
Troubleshoot DNS, ports, routes, and socket states with practical command workflows.
Lesson 6
systemd Services and journalctl
Manage service lifecycle, startup order, and persistent logs with systemd tooling.
Lesson 7
Shell Scripting Basics with Bash
Create reusable scripts for health checks, backup, and operational automation.
Lesson 8
Advanced
Scale up Linux operations with storage engineering, host hardening, cloud patterns, and performance tuning.
Storage and Filesystems: LVM and RAID
Expand storage safely and design resilient disk strategies for data-heavy workloads.
Lesson 9
Security Hardening: SSH, Firewall, and Audit
Reduce attack surface with hardened SSH, firewall policy, and auditability controls.
Lesson 10
Linux in Cloud and Containers
Translate host-level Linux knowledge into VM, container, and Kubernetes operations.
Lesson 11
Performance Tuning and Capacity Planning
Measure bottlenecks and tune CPU, memory, disk, and network for predictable service SLOs.
Lesson 12
Hands-on
Practice realistic Linux operations through build, break/fix, incident response, and interview prep scenarios.
Lab: Server Bootstrap and Baseline Hardening
Provision and secure a fresh host with repeatable baseline checks.
Lesson 13
Lab: Troubleshoot High CPU, Memory, and Disk
Run a disciplined triage workflow to identify and fix resource pressure issues.
Lesson 14
Debugging Linux Production Incidents
Coordinate diagnosis and safe mitigation during high-stakes outages.
Lesson 15
Interview Preparation: Linux for DevOps
Consolidate key Linux interview patterns from beginner to scenario-based rounds.
