Bash Arrays
Working with Arrays in Bash
This section explains how to create and manipulate arrays in Bash scripts.
Arrays allow you to store multiple values in a single variable, making data management easier.
Creating Arrays
To create an array in Bash, use the following syntax.
Arrays can store multiple values, and each value is indexed starting from zero:
Example: Create an Array
my_array=("value1" "value2" "value3")Use descriptive names for arrays to indicate their purpose.
Accessing Array Elements
To access elements in a Bash array, use the index of the element.
The index is specified in square brackets:
Example: Access Array Elements
echo ${my_array[0]}Modifying Array Elements
You can modify elements in a Bash array by specifying the index and assigning a new value:
Example: Modify Array Elements
my_array[1]="new_value"
