In this chapter, we will discuss how to use shell arrays in Unix. A shell variable is capable enough to hold a single value. These variables are called scalar variables. Shell supports a different type of variable called an array variable. This can hold multiple values at the same time.


The use of array variable structures can be invaluable. This recipe describes several methods for declaring arrays in bash scripts.
