idioms for returning multiple values in shell scripting

Question

Are there any idioms for returning multiple values from a bash function within a script?

http://tldp.org/LDP/abs/html/assortedtips.html describes how to echo multipl

Answer 1

Yet another way:

function get_tuple()
{
  echo -e "Value1\nValue2"
}

IFS=$'\n' read -d '' -ra VALUES < <(get_tuple)
echo "${VALUES[0]}" # Value1
echo "${VALUES[1]}" # Value2
