Extracting x random values from a bash array

Decided to write an answer, as I found the --input-range option to shuf that turned out handy:

N=3
ARRAY=( zero one two three four five )

for index in $(shuf --input-range=0-$(( ${#ARRAY[*]} - 1 )) -n ${N})
do
    echo ${ARRAY[$index]}
done

How about this:

for i in {1..10}; do
    echo $i
done | shuf

That will return all the numbers. If you only want a specific amount, do this:

numbers=5    
for i in {1..10}; do
    echo $i
done | shuf | head -$numbers

And if you want to change the numbers, just change the {1..10} variable to whatever you want.
