Split string into an array in Bash

Question

In a Bash script I would like to split a line into pieces and store them in an array.

The line:

Paris, France, Europe

I would like

Answer 1

Try this

IFS=', '; array=(Paris, France, Europe)
for item in ${array[@]}; do echo $item; done

It's simple. If you want, you can also add a declare (and also remove the commas):

IFS=' ';declare -a array=(Paris France Europe)

The IFS is added to undo the above but it works without it in a fresh bash instance
