Answer / narendrasairam

Though cut command works, if the string is too long you cant
expect redundancy in the code. So, better to translate the
spaces first and then reading the lines.

echo "enter the string :"
read string

echo $string | tr " " "\n" | sed '/^$/d' > lines.out

while read line
do
echo $line
done < lines.out
