Bash (Scripting) - Append values to an array (+=)

Let's say you have an array of fruit.

fruit=(banana apple orange grapes)


The += operator can be used to append values to the array. In this example, pineapple is appended to the fruit array.



The array can be printed.

echo $fruit


Echoing the array will show that pineapple has been appended to the array.

banana apple orange grapes pineapple

echo "$fruit" # prints the first element of the array printf '%s\n' "${fruit[@]}" # prints each element on its own line IFS=',' echo "${fruit[*]}" # prints comma separated values IFS=$' \t\n' # Restores IFS to its default value
