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
