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.

A shell script is a computer program designed to be run by the Unix shell, a command line interpreter. It is a text file containing a sequence of shell commands and constructs that perform a routine task. This sequence is typically executed by entering the name of the script on the command line. Alternatively, a script can be initialised using cron, a time-based job scheduler. It makes little sense to continually type a sequence of commands at a command prompt, particularly if they are long, complex, or difficult to remember. Scripting offers the virtue of alleviating this unnecessary burden.
Right from a simple to the complex script can be developed using Shell Scripting. Shell scripting is nothing but series of UNIX commands written in a plain text file to accomplish a specific task. And with the help of shell scripting, some tasks of the day to day life can be automated. There are hardly few documents available over the internet on shell scripting interview questions and answers. Hence, I have chosen Shell Scripting as my topic to help those who are in need of it. It can also be defined as an interface between a user and operating system. Ans: Shell scripting is nothing but series or sequence of UNIX commands written in a plain text file.

I'll have you mastering Unix shell scripting in no time. This tutorial is written to help people understand some of the basics of shell script programming aka shell scripting , and hopefully to introduce some of the possibilities of simple but powerful programming available under the Bourne shell. As such, it has been written as a basis for one-on-one or group tutorials and exercises, and as a reference for subsequent use. You are reading Version 2. Always check there for the latest copy.
