This comprehensive course provides a complete roadmap to mastering Linux as a DevOps engineer or developer. You’ll start with an introduction to Linux and cloud setup, learning what an operating system is, the history and evolution of Unix and Linux, and how to create an AWS Free Tier account. The opening lectures guide you through launching and connecting to a Linux virtual machine on AWS EC2, understanding the Linux filesystem hierarchy and navigating your environment like a professional.

You’ll then progress to working with text files and directories using essential Linux commands. Lessons cover listing and navigating directories, reading files with less, more, tail and head, creating and editing files with touch and nano, managing directories, and searching for files and text using file, find and grep commands. These skills form the backbone of efficient Linux system administration.

Next, you’ll build expertise in user account management and permissions. You’ll learn to create and manage user accounts, understand and change file permissions, connect to EC2 Linux VMs as different users, change ownership with chown, manage sudo privileges, and work with su and sudo commands securely. The course then teaches you how to install and manage software packages with APT and YUM, covering both Ubuntu and Amazon Linux distributions.

You’ll also master service management using systemctl and the service command, process management and monitoring with ps, kill, top, bg, fg, nice and renice, and virtual memory monitoring with vmstat. Networking essentials include checking interfaces with ifconfig, viewing network statistics with netstat, testing connectivity with ping, and transferring data using curl and wget.

Further modules cover backup and restore using tar and gzip, automating tasks with cron jobs, handling input/output redirection, using wildcards, creating and managing symbolic and hard links, shutting down and rebooting systems safely, viewing and managing log files, and transferring files securely between Linux and your local desktop with WinSCP. By the end of the course, you’ll have the confidence to manage Linux servers in cloud and on-premise environments, streamline DevOps workflows and support software deployments effectively.
