How to echo variables in vertical order

Question

I need help in this echo command. I want it to echo variables in vertical order but this didn't work for me

A=$(initctl status worker1)
B=$(initctl status worker2)
var="$(echo -e "\n$A \n$B")"

Answer 1

I would not put that echo inside of the var. Maybe this can help?

var="${A}\n${B}"
echo -e $var

Answer 2

A="$(initctl status worker1)"
B="$(initctl status worker2)"
var="$(echo -e "$A\n$B")"

then you can print the vertically formatted output, eg using:

echo "$var"
