How do I split a string on a delimiter in Bash?

Question

I have this string stored in a variable:

IN=\"bla@some.com;john@home.com\"

Now I would like to split the strings by ; delimite

Answer 1

If no space, Why not this?

IN="bla@some.com;john@home.com"
arr=(`echo $IN | tr ';' ' '`)

echo ${arr[0]}
echo ${arr[1]}
