Arrays

• An array is a collection of items all of the same sort, stored in a single variable. Think, perhaps, of eggs in a 12-element array called an egg carton.

• Arrays count from 0. You will forget this, usually at the worst possible time, so try hard to remember:

Arrays count from zero!

• To declare an array: declare -a myArray1

• To initialize:

declare -a myArray1=(1 2 3 4 5 6)

declare -a myArray2

myArray2=(1 2 3 4 5 6)

declare -a myArray3

read -a myArray3

[stdin] 1 2 3 4 5 6 [ENTER]
