Get the index of a value in a Bash array

Question

I have something in bash like

myArray=('red' 'orange' 'green') 

And I would like to do something like

echo ${myArray['green']} 

Which in this case would output 2. Is this achievable?

Answer 1

This will do it:

#!/bin/bash  my_array=(red orange green) value='green'  for i in "${!my_array[@]}"; do    if [[ "${my_array[$i]}" = "${value}" ]]; then        echo "${i}";    fi done 

Obviously, if you turn this into a function (e.g. get_index() ) - you can make it generic
