ramu,sony,"raju ravi ramya"
ravi,sarah,"sowmya sorry sangam"

any body help to find solution. either perl script or any shell script

Would this work for you?
(where new_lines is the name of your file)

cat new_lines | sed 's/" /" ~/' | tr "\n" " " | tr "~" "\n"

use tr
also see ASCII - Wikipedia, the free encyclopedia to know the octal for new line, which is 012

tr -d '\012' < new_lines

This also works in most cases, and is easier to remember. :-)

tr -d '\r'
