BASH-Array array

BASH-Array array

Array declaration: declare-an array actually does not need to declare, but assigns values to variables directly as an array. BASH will know that it is an array.

Array assignment:

You can also assign a value to the entire array: test= (var1 var2 var3... VarN)

Test= ([0] = var1 [1] = var2 [2] = var3... [n] = varN)

To assign values to an array, please refer to the definition of ordinary variables test [0] = var1.

Test [1] = var2

Test [2] = var3

Test [N] = varN-1

Array reference: ${test [subscript]}

For example:

$echo ${test [0]} var1

FYI. In addition, there are two special symbols, the * and @ signs, which refer to all array elements:

$echo ${test [*]} / * there are no spaces on both sides. This is indicated here because exblog recognizes errors.

Var1 var2 var3

# echo ${name [@]}

Var1 var2 var3

To display the number of elements in the entire array, use:

$echo ${# name [@]} 3
