Command Line Confidence

You know your way around code, but the command line still feels like a foreign language. Every time you need to do something in the terminal, you're back on Stack Overflow, copying commands you half-understand.

Command Line Confidence fixes that—one nugget at a time.

101 practical concepts—one per page, each self-contained. Real examples you can type and run immediately. No 50-page chapters—each concept fits on one page. Challenges to cement your understanding.

From grep, sed, and awk to SSH and rsync. From pipes and redirects to process management and shell scripting. Each nugget builds your intuition so you stop memorizing and start understanding.

Covers file operations, text processing, permissions, networking, job scheduling, and scripting fundamentals. Examples use Bash syntax but work in Zsh, Fish, and other shells.

Flip to any page. Learn something useful. Build real confidence.
