{"product_id":"unix-and-linux-systems-tammy-tech-9798193767473","title":"UNIX and Linux Systems: A Beginner's Guide to the Command Line, Shell Scripting, and Automation","description":"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.\u003cbr\u003eYou'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.\u003cbr\u003eThat stops here.\u003cbr\u003eUNIX 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.\u003cbr\u003eWhat makes this book different\u003cbr\u003eMost 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.\u003cbr\u003eOver 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. \u003cp\u003e\u003c\/p\u003e\u003cb\u003eInside you'll learn to: \u003c\/b\u003e\u003cbr\u003eNavigate the filesystem, manage files, and never lose work to a mistyped rm\u003cbr\u003eDecode permissions, users, groups, and sudo - and finally understand \"permission denied\"\u003cbr\u003eMaster pipes and redirection, the grammar that connects every command\u003cbr\u003eUse grep, sed, and awk to slice any text file into answers\u003cbr\u003eFind any file by name, size, age, owner, or permission - and act on all of them at once\u003cbr\u003eWrite scripts that validate their inputs, handle their own errors, and clean up after themselves\u003cbr\u003eSchedule jobs with cron and systemd timers that actually run when you're not watching\u003cbr\u003eBuild six complete automation projects: backups, log management, bulk processing, health monitoring, reporting, and zero-downtime deployment \u003cp\u003e\u003c\/p\u003eWritten 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.\u003cbr\u003e24 chapters. 400+ pages. Hundreds of working code examples.\u003cbr\u003eEvery chapter ends with exercises. Every script is one you can use.\u003cbr\u003eOpen the terminal. This time, don't close it.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Tammy Tech\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9798193767473\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 08\/19\/2026\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 412\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 2.09lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 11.00h x 8.50w x 0.84d","brand":"Tammy Tech","offers":[{"title":"Paperback","offer_id":49174532358399,"sku":"9798193767473","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_faba5ba1-b5d4-4e68-acf5-2f4b12cdb644.jpg?v=1788960135","url":"https:\/\/www.whiterainbookhouse.com\/products\/unix-and-linux-systems-tammy-tech-9798193767473","provider":"WR Book House","version":"1.0","type":"link"}
