Hi all,
I have a big file (2.7G) containing multiple records
in this format:

Each record starts with ">". I want to read each
record once at a time.I hear about a special variable
call $/ might do the job but not sure how to use it. I
wonder if anyone could help me out.
Word wrapping possibly mangled the example records, could you please
upload a handful of them in a file somewhere?
