Shell Array notes.

1), the definition of the array (self-dividing):
Static array= (123)

Dynamic array array= ($ (command))

Example:

array= ($ (LS)) echo ${bb[@]} color01.sh color.sh ip.sh touch.sh tou.sh user.sh while01.sh while_02.sh

2), display the contents of the array
Echo ${array[@]}

Echo ${array[*]}

Show one of the character in the array, note that the first one is starting from 0 as follows:

Echo ${bb[3]}
