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 ${         


        

Answer 1

I wanted something similar myself and avoiding a loop, came up with ...

myArray=('red' 'orange' 'green')
declare -p myArray | sed -n "s,.*\[\([^]]*\)\]=\"green\".*,\1,p"

... which leaves stdout unsullied should the element not be found...

$ myArray=('red' 'orange' 'green')
$ declare -p myArray | sed -n "s,.*\[\([^]]*\)\]=\"green\".*,\1,p"
2

$ declare -p myArray | sed -n "s,.*\[\([^]]*\)\]=\"gren\".*,\1,p"
$

After which I googled, found this question and thought I'd share ;)
