Shell scripting skills never go out of style. It's the shell that unlocks the real potential of Unix. Shell scripting is essential for Unix users and system administrators-a way to quickly harness and customize the full power of any Unix system. With shell scripts, you can combine the fundamental Unix text and file processing commands to crunch data and automate repetitive tasks. But beneath this simple promise lies a treacherous ocean of variations in Unix commands and standards. Classic Shell Scripting is written to help you reliably navigate these tricky waters. Writing shell scripts requires more than just a knowledge of the shell language, it also requires familiarity with the individual Unix programs: why each one is there, how to use them by themselves, and in combination with the other programs. The authors are intimately familiar with the tips and tricks that can be used to create excellent scripts, as well as the traps that can make your best effort a bad shell script. With Classic Shell Scripting you'll avoid hours of wasted effort. You'll learn not only write useful shell scripts, but how to do it properly and portably. The ability to program and customize the shell quickly, reliably, and portably to get the best out of any individual system is an important skill for anyone operating and maintaining Unix or Linux systems. Classic Shell Scripting gives you everything you need to master these essential skills.
About this product: An Atlantic correspondent uncovers the true cost-in economic, political, and psychic terms-of our penchant for making and buying things as cheaply as possible
From the shuttered factories of the rust belt to the look-alike strip malls of the sun belt-and almost everywhere in between-America has been transformed by its relentless fixation on low price. This pervasive yet little examined obsession is arguably the most powerful and devastating market force of our time-the engine of globalization, outsourcing, planned obsolescence, and economic instability in an increasingly unsettled world.
Low price is so alluring that we may have forgotten how thoroughly we once distrusted it. Ellen Ruppel Shell traces the birth of the bargain as we know it from the Industrial Revolution to the assembly line and beyond, homing in on a number of colorful characters, such as Gene Verkauf (his name is Yiddish for "to sell"), founder of E. J. Korvette, the discount chain that helped wean customers off traditional notions of value. The rise of the chain store in post-Depression America led to the extolling of convenience over quality, and big-box retailers completed the reeducation of the American consumer by making them prize low price in the way they once prized durability and craftsmanship.
The effects of this insidious perceptual shift are vast: a blighted landscape, escalating debt (both personal and national), stagnating incomes, fraying communities, and a host of other socioeconomic ills. That's a long list of charges, and it runs counter to orthodox economics which argues that low price powers productivity by stimulating a brisk free market. But Shell marshals evidence from a wide range of fields-history, sociology, marketing, psychology, even economics itself-to upend the conventional wisdom. Cheap also unveils the fascinating and unsettling illogic that underpins our bargain-hunting reflex and explains how our deep-rooted need for bargains colors every aspect of our psyches and social lives. In this myth-shattering, closely reasoned, and exhaustively reported investigation, Shell exposes the astronomically high cost of cheap.

The two sandstone monoliths towering over the southern Colorado landscape are wrapped in ancient mystery. To the local tribes, they are the Twin War Gods, sons of the moon goddess, White Shell Woman.

About this product: September Eleventh . . . war in Iraq . . . turmoil in the Middle East . . . an impending war with Iran. They have one thing in common: oil. And the world is running out. The Shell Game is a thrilling novel that faces the end of oil and the next big attack on American soil. This fictional tale resonates with chilling facts from real-life informants in the oil industry and the U.S. government, piecing together the terrifying truth about a nation addicted to oil. The tale opens in 2007 as the CIA plans a nuclear attack on an American city, blaming the deaths of millions of Americans on Iran and inciting a retaliatory strike that will place the U.S. in control of Iran's oil resources. Five years later, petroleum geologist Ashley "Ace" Futrell discovers that the world's oil supply is rapidly nearing its end. When his wife - a former national security advisor - is suddenly murdered, Ace finds himself hurtling down a rabbit's hole that leads to the brink of World War III.
