This command is creating an array called variable and assigning it the values item_a, item_b, and item_c. The array is created using the local keyword which is commonly used in scripting languages to declare a variable with a local scope, meaning it only exists within the current block or function.
The syntax used to create the array is (${item_a item_b item_c}). The values in the parentheses are separated by spaces and each value is considered an element of the array. So, the resulting variable array will contain three elements: item_a, item_b, and item_c.
