UNIX and Linux Systems: A Beginner's Guide to the Command Line, Shell Scripting, and Automation (Paperback) (ISBN-13: 9798193767473)

Most Linux books teach you 100 commands. This one teaches you why they fit together - and then has you automating your work by Chapter 13.
You've typed sudo because a forum told you to. You've copied a command you didn't understand and hoped. You've opened a terminal, looked at the blinking cursor, and closed it again.
That stops here.
UNIX and Linux Systems starts from absolutely nothing - no prior experience, no assumptions - and takes you to writing production-quality shell scripts that run themselves at three in the morning without you.
What makes this book different
Most beginner guides stop at "here are some commands." This one goes further, because commands you don't understand are commands you can't combine. You'll learn why ls has no wildcard feature and doesn't need one, why deleting a log file doesn't free up disk space, and why your script works perfectly by hand and silently fails when scheduled.
Over half the book is devoted to shell scripting and automation - the part that turns Linux from something you use into something that works for you.

Inside you'll learn to:
Navigate the filesystem, manage files, and never lose work to a mistyped rm
Decode permissions, users, groups, and sudo - and finally understand "permission denied"
Master pipes and redirection, the grammar that connects every command
Use grep, sed, and awk to slice any text file into answers
Find any file by name, size, age, owner, or permission - and act on all of them at once
Write scripts that validate their inputs, handle their own errors, and clean up after themselves
Schedule jobs with cron and systemd timers that actually run when you're not watching
Build six complete automation projects: backups, log management, bulk processing, health monitoring, reporting, and zero-downtime deployment

Written for: Complete beginners. Developers who've used Linux for years without understanding it. Students, career-changers, and anyone facing a server for the first time.
24 chapters. 400+ pages. Hundreds of working code examples.
Every chapter ends with exercises. Every script is one you can use.
Open the terminal. This time, don't close it.
