Below methods will work. You could use either cut or awk
echo "read data"
read data
echo $data | cut -f1 -d" "
echo $data | cut -f2 -d" "
echo $data | cut -f3 -d" "
echo $data |awk -F" " '{print $1}'
echo $data |awk -F" " '{print $2}'
echo $data |awk -F" " '{print $3}'

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
