Working with arrays

An array is a list of variables. For example, we can create an array called FRUIT, which will contain the names of many fruits. The array does not have a limit on how many variables it may contain. It can contain any type of data. The first element in an array will have the index value of 0:

[student@localhost ~]$ FRUITS=(Mango Banana Apple)
[student@localhost ~]$ echo ${FRUITS[*]}
Mango Banana Apple
[student@localhost ~]$ echo $FRUITS[*]
Mango[*]
[student@localhost ~]$ echo ${FRUITS[2]}
Apple
[student@localhost ~]$ FRUITS[3]=Orange
[student@localhost ~]$ echo ${FRUITS[*]}
Mango Banana Apple Orange
