Split string with IFS using Bash?

Question

I have a string like:

Spain-South Africa:2-1

And I want to split it like:

Spain-South Africa
2-1

I have tried to split it by IFS=':' but it gives me:

Spain-South

Africa
2-1

My code:

Cannot reproduce, but you are probably either not setting IFS correctly for the read command, or you are not displaying the output correctly.

$ str="Spain-South Africa:2-1"
$ IFS=: read -ra results <<< "$str"
$ declare -p results
declare -a results=([0]="Spain-South Africa" [1]="2-1")

Based on your short-lived comment, you want something like

while IFS=: read -ra results; do
    ...
done < "$1"

rather than

for str in $(cat "$1"); do
    ...
done
