Try using this..[...]
OLDIFS=$IFS
IFS="|"
for line in `cat test.data`;
do
echo $line;
done
IFS=$OLDIFS
This is simple and crisp.
And you oversaw three more problems: empty lines are discarded,
try it with a line containing "*", and if IFS was previously
unset, it becomes set to the empty string which has a totally
different meaning.
Using loops in shells always leads to this kind of corner case
problems. Shells are not meant to be used like that, avoid loops
to process text.
