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

Use the set built-in to load up the $@ array:

IN="bla@some.com;john@home.com"
IFS=';'; set $IN; IFS=$' \t\n'

Then, let the party begin:

echo $#
for a; do echo $a; done
ADDR1=$1 ADDR2=$2
