is the name of the array variable you want to create. The curly braces{}
are used to specify the variable name.=(${item_a item_b item_c})
is the assignment part. The values inside the parentheses()
are the elements of the array, separated by spaces. In this case, the array will have three elements:item_a
,item_b

and assigns it values item_a
, item_b
, and item_c
