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

I am new to bash, But found this code helping.

function return_multiple_values() {
        eval "$1='What is your name'"
        eval "$2='my name is: BASH'"
    }
    
    return_var=''
    res2=''
    return_multiple_values return_var res2
    echo $return_var
    echo $res2
