Scripting is a way to harness and customize the power of any Unix system, and it's an essential skill for any Unix users, including system administrators and professional OS X developers. But beneath this simple promise lies a treacherous ocean of variations in Unix commands and standards.bash Cookbook teaches shell scripting the way Unix masters practice the craft. It presents a variety of recipes and tricks for all levels of shell programmers so that anyone can become a proficient user of the most common Unix shell -- the bash shell -- and cygwin or other popular Unix emulation packages. Packed full of useful scripts, along with examples that explain how to create better scripts, this new cookbook gives professionals and power users everything they need to automate routine tasks and enable them to truly manage their systems -- rather than have their systems manage them.

    Being a hacker has nothing to do with cyberterrorism, and it doesn’t even necessarily relate to the open-source movement. Being a hacker has more to do with your underlying assumptions about stress, time management, work, and play. It’s about harmonizing the rhythms of your creative work with the rhythms of the rest of your life so that they amplify each other. It is a fundamentally new work ethic that is revolutionizing the way business is being done around the world.Without hackers there would be no universal access to e-mail, no Internet, no World Wide Web, but the hacker ethic has spread far beyond the world of computers. It is a mind-set, a philosophy, based on the values of play, passion, sharing, and creativity, that has the potential to enhance every individual’s and company’s productivity and competitiveness. Now there is a greater need than ever for entrepreneurial versatility of the sort that has made hackers the most important innovators of our day. Pekka Himanen shows how we all can make use of this ongoing transformation in the way we approach our working lives.
