Ron Peters

Ron Peters spent more than ten years administering Linux and Unix systems while building a very large library of shell scripts. He realized that the world is full of how–to documents, but not many seem to read them, nor can many system administrators lay claim to being shell scripting experts. He apologizes that it took him so long to make his efforts known to the world. He is married with two children and very happy that he found the time to write this book.

System administrators need libraries of solutions that are ingenious but understandable. They don’t want to reinvent the wheel, but they don’t want to reinvent filesystem management either! Expert Shell Scripting is the ultimate resource for all working Linux, Unix, and OS X system administrators who would like to have short, succinct, and powerful shell implementations of tricky system scripting tasks.
