Printing the Arrays
After declaring the array, if we wanted to display all the elements in the array we can use the @ symbol.
#!/bin/usr/env bash
declare -a sport=(
[0]=football
[1]=cricket
[2]=hockey
[3]=basketball
)
echo "${sport[@]}"
echo "${array_name[@]}"
We use the [@] as an index to the array to display all the elements. All the elements are printed with space-separated, The quotes around the variable expands and print all the elements in the array.
