# Example 2 for Bash Tips show 15 - you can also use a 'for' loop to load an
# array
#-------------------------------------------------------------------------------

#
# Initialise an array
#
items=()

#
# Populate the array with random words
#
for word in $(grep -E -v "'s$" /usr/share/dict/words | shuf -n 5); do
    items+=( "$word" )
done

#
# Print the array with word numbers
#
for ((i = 0, j = 1; i < ${#items[@]}; i++, j++)); do
    echo "$j: ${items[$i]}"
done
