Everyday Use

The practical Linux skills you need before going deep.

You’ve finished Zero to Terminal — you know what a terminal is and can run basic commands. Now it’s time to build real muscle memory with the tools you’ll use every single day as a DevOps engineer.

These 5 modules bridge the gap between “I can use a terminal” and “I understand how Linux works under the hood.” Minimal theory, focused on the practical mental models you need — hands-on practice with the tools that matter.

Modules

#	Module	Time	What You’ll Learn
0.1	The CLI Power User (Search & Streams)	70–100 min	Wildcards, pipes, redirects, find, grep
0.2	Environment & Permissions (Who You Are & Where You Are)	80–110 min	$PATH, .bashrc, chmod, chown, sudo
0.3	Process & Resource Survival Guide	90–120 min	ps, top, kill, background jobs, disk usage
0.4	Services & Logs Demystified	80–110 min	systemctl, journalctl, daemons
0.5	Everyday Networking Tools	70–100 min	ping, curl, ss, dig, traceroute

These are planning estimates copied from the five module headers, not measured learner completion times. Their arithmetic gives an aggregate range of 390–540 minutes (about 6 hours 30 minutes–9 hours); individual setup, reading, and practice time will vary.
