@ donadarsh
your code will also trim the spaces between the words of the query
It will keep only 1 white space between each word. give a try on simple lines

Code:
echo "ABCS      asdaa     sdas ds   adasasd       sadasd"|tr -s " "

Please post a sample of the desired output.

My answer assumed the only thing on those empty lines with the new-line character. If there are spaces or tabs or any whitespace, then it would not work.
What is on those seemingly blank lines?

This should remove empty lines with any kind of whitespace..
Code:
awk NF file
