Book Description
The key to mastering any Unix system, especially Linux and Mac OS X, is a thorough knowledge of shell scripting. 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.

Book Description
“It rained cats and dogs”, “I know where his shoe pinches”, “Yes, it was really a blessing in disguise”… These idioms are often used in common language in our day to day talk or even correspondence. Their usage makes the communication and message to be conveyed quite effective. Dictionary defines idiom as “a group of words whose meaning is different from the meaning of the individual words.” Idiom is a combination of words with figurative meanings. It often creates a picturesque image and that image conveys the meaning. For e.g. ‘where the shoe pinches’ the image automatically creates the image of pain and trouble and the place where there is trouble. Similarly, ‘add fuel to the fire’—it creates the image of fire blazing more and the meaning of aggravation comes out. The following example is widely employed to illustrate the point.
