How to pass an associative array as argument to a function in Bash?

Question

How do you pass an associative array as an argument to a function? Is this possible in Bash?

The code below is not working as expected:

function iter         


        

Answer 1

From the best Bash guide ever:

declare -A fullNames
fullNames=( ["lhunath"]="Maarten Billemont" ["greycat"]="Greg Wooledge" )
for user in "${!fullNames[@]}"
do
    echo "User: $user, full name: ${fullNames[$user]}."
done

I think the issue in your case is that $@ is not an associative array: "@: Expands to all the words of all the positional parameters. If double quoted, it expands to a list of all the positional parameters as individual words."
