110 cards
This deck covers the core command-line skills and system concepts that form the foundation of Linux administration. You'll find questions on everyday commands like ls, grep, find, awk, and sed, as well as important background topics such as the filesystem hierarchy, the /proc virtual filesystem, and how file permissions and ownership work. There are also cards on process management, covering tools like ps, top, kill, nice, and job control, which are essential for keeping a Linux system running smoothly.
It's well suited to anyone preparing for a sysadmin role, a Linux certification, or simply wanting to become more confident on the terminal. Beginners who have just installed their first Linux distribution will find a clear path through the basics, while more experienced users can use the deck to fill in gaps and reinforce less familiar areas like special permission bits or the finer points of process signals.
Because Linux administration is a hands-on subject, the cards will stick much faster if you try out each command on a real machine or virtual environment as you study. A quick tip: aim to review a small batch of cards each day rather than cramming everything at once. Spaced, repeated practice mirrors the way these tools become second nature through daily use, and you'll soon find yourself reaching for the terminal without even thinking about it.
