If you have a string "one two three", which shell command
would you use to extract the strings?
Answer Posted / 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
