How to get the first element of an array in Bash

In this tutorial, we are going to learn about how to get the first element of an array in Bash.

Consider, we have the following array.

array=(10 20 30 40 50)

Now, we want to get the first element 10 from the above array.

To get the first element (10) from the array, we can use the subscript [ ] syntax by passing an index 0.

In bash arrays are zero-indexed, so the first element index is 0.

Here is an example:

array=(10 20 30 40 50)

echo ${array[0]}

Output:

10
