How to return an array in bash without using globals?

Question

I have a function that creates an array and I want to return the array to the caller:

create_array() {
  local my_list=(\"a\", \"b\", \"c\")
  echo \"${my_li         


        

Answer 1

You can try this

my_algorithm() {
  create_array list
  for element in "${list[@]}"
  do
    echo "${element}"
  done
}

create_array() {
  local my_list=("1st one" "2nd two" "3rd three")

  eval "${1}=()"
  for element in "${my_list[@]}"
  do
    eval "${1}+=(\"${element}\")"
  done
}

my_algorithm

The output is

1st one
2nd two
3rd three
