The Linux & Bash roadmap
Everything this course covers, in the order you'll learn it. Open a stage to see why it matters and jump to its lesson.
01Navigation basicsstart here
Find your way around any server without a GUI. Everything else depends on this.
Lesson 1: The shell and the filesystem →02Editing files
Config lives in text files. You need to edit them over SSH, where there is no VS Code.
Lesson 2: Editing files · coming soon03Shell basics
Know how the shell finds commands, where output goes, and when you are root.
Lesson 3: Shell basics · coming soon04Working with files
Most "it works on my machine" bugs are really permission or path problems.
Lesson 4: Working with files · coming soon05Text processing
Logs are text. Small tools joined with pipes answer most incident questions in seconds.
Lesson 5: Text processing · coming soon06Server review
The five-minute health check you run the moment you log into a slow server.
Lesson 6: Server review · coming soon07Process management
Find what is eating the CPU, stop it cleanly, and keep jobs running after you log out.
Lesson 7: Process management · coming soon08Users & groups
Every service should run as its own user. This is the first layer of security.
Lesson 8: Users & groups · coming soon09Services with systemd
How real apps run on servers: start on boot, restart on crash, logs in one place.
Lesson 9: Services with systemd · coming soon10Package management
Install, pin and upgrade software the same way on every server.
Lesson 10: Package management · coming soon11Disks & filesystems
"Disk full" is one of the most common outages. Learn to find space and add more.
Lesson 11: Disks & filesystems · coming soon12Booting Linux
When a server will not come back after a reboot, this is where you look.
Lesson 12: Booting Linux · coming soon13Networking
Half of DevOps debugging is "can A talk to B?". These are the building blocks.
Lesson 13: Networking · coming soon14Shell scripting
Turn the commands you repeat into scripts that run the same way every time.
Lesson 14: Shell scripting · coming soon15Troubleshooting
A calm, repeatable way to find out why the network or a service is broken.
Lesson 15: Troubleshooting · coming soon16Containers on Linux
Containers are just Linux features. This stage is the bridge to the Docker course.
Lesson 16: Containers on Linux · coming soonCourse complete · ready for the next one
