Portable shell scripting is the future of modern Linux, OS X, and Unix command–line access. Beginning Portable Shell Scripting: From Novice to Professional teaches shell scripting by using the common core of most shells and expands those principles to all of scripting. You will learn about portable scripting and how to use the same syntax and design principles for all shells. You’ll discover about the interaction between shells and other scripting languages like Ruby and Python, and everything you learn will be shown in context for Linux, OS X, bash, and AppleScript. What you’ll learn This book will prime you on not just shell scripting, but also the modern context of portable shell scripting. You will learn The core Linux/OS X shell constructs from a portability point of view How to write scripts that write other scripts, and how to write macros and debug them How to write and design shell script portably from the ground up How to use programmable utilities and their inherent portability to your advantage, while pinpointing potential traps Pulling everything together, how to engineer scripts that play well with Python and Ruby, and even run on embedded systems Who this book is for This book is for system administrators, programmers, and testers working across Linux, OS X, and the Unix command line.

Operation Protective Edge, launched in early July 2014, was the third major Israeli assault on the Gaza Strip in six years. It was also the most deadly. By the conclusion of hostilities some seven weeks later, 2,200 of Gaza’s population had been killed, and more than 10,000 injured. In these pages, journalist Mohammed Omer, a resident of Gaza who lived through the terror of those days with his wife and then three-month-old son, provides a first-hand account of life on-the-ground during Israel’s assault. The images he records in this extraordinary chronicle are a literary equivalent of Goya’s “Disasters of War”: children’s corpses stuffed into vegetable refrigerators, pointlessly because the electricity is off; a family rushing out of their home after a phone call from the Israeli military informs them that the building will be obliterated by an F-16 missile in three minutes; donkeys machine-gunned by Israeli soldiers under instructions to shoot anything that moves; graveyards targeted with shells so that mourners can no longer tell where their relatives are buried; fishing boats ablaze in the harbor. Throughout this carnage, Omer maintains the cool detachment of the professional journalist, determined to create a precise record of what is occurring in front of him. But between his lines the outrage boils, and we are left to wonder how a society such as Israel, widely-praised in the West as democratic and civilized, can visit such monstrosities on a trapped and helpless population.

One thing about a new day--you really never know where it will go, even if you know where it starts. Marcel the Shell with Shoes On is walking on the blanket when he is unexpectedly launched high into the air. Tumbling through space, the bird's-eye view offers our small friend not only a glimpse of the important things in life--his beloved Nana who sleeps in a fancy French bread, a stinky shoe, and a monstrous baby--but also a much bigger picture. Sometimes the most wonderful discoveries are the ones we least expect.

Fun and facts for children from one of the most trusted names in learning: the Smithsonian Institution.
