Customer Reviews

Brilliant book  July 26, 2011
by


Very helpful, understandable textbook. I have very little experience with Linux command line, but I've found this to be an excellent help. All commands are demystified and defined. Bash and C shells are discussed and demystified. I also liked the clear organization of this book. It takes one glance in the list to figure out what do you need and how to get it. A book that is a must for everyone's bookshelf. As for me, I'm very happy to deal with ecampus. The textbook looks as if it is new and the price was good.

Summary

For use with all versions of Linux, including Ubuntu,™ Fedora,™ openSUSE,™ Red Hat,® Debian, Mandriva, Mint, and now OS X, too!

-Get more done faster, and become a true Linux guru by mastering the command line!

The Most Useful Linux Tutorial and Reference, with Hundreds of High-Quality Examples for Every Distribution–Now Covers OS X and Perl, Too!

To be truly productive with Linux, you need to thoroughly master shells and the command line. Until now, you had to buy two books to gain that mastery: a tutorial on fundamental Linux concepts and techniques, plus a separate reference. Now, there’s a far better solution. Renowned Linux expert Mark Sobell has brought together comprehensive, insightful guidance on the tools system administrators, developers, and power users need most, and an outstanding day-to-day reference, both in the same book.

This book is 100 percent distribution and release agnostic: You can use it with any Linux system, now and for years to come. Use Macs, too? This new edition adds comprehensive coverage of the Mac OS X command line, including essential OS X-only tools and utilities other Linux/UNIX books ignore.

Packed with hundreds of high-quality, realistic examples, this book gives you Linux from the ground up: the clearest explanations and most useful knowledge about everything from filesystems to shells, editors to utilities, and programming tools to regular expressions. Sobell has also added an outstanding new primer on Perl, the most important programming tool for Linux admins seeking to automate complex, time-consuming tasks.

A Practical Guide to Linux®; Commands, Editors, and Shell Programming, Second Edition, is the only book to deliver

-Better, more realistic examples covering tasks you’ll actually need to perform

-Deeper insight, based on Sobell’s immense knowledge of every Linux and OS X nook and cranny

-Tips and tricks for customizing the shell and using it interactively from the command line
