Get the index of a value in a Bash array

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?

Solution

  • 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
