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

myArray=('red' 'orange' 'green')
echo ${myArray[@]}
arrayElementToBeRemoved='orange'
echo "removing element: $arrayElementToBeRemoved"
# Find index of the array element (to be kept or preserved)
let "index=(`echo ${myArray[@]} | tr -s " " "\n" | grep -n "$arrayElementToBeRemoved" | cut -d":" -f 1`)-1"
unset "myArray[$index]"
echo ${myArray[@]}
