reading a Unix Generated text file

Hey everyone,
                                                I have this Unix Genarated text file that I have to go and get every day  to update my
database.  What i'm actually wondering is how to parse the actual data and put them in
their appropriate fields.  Is there any components or  procedures which could help me?  If
not how can I detect the codes which separates every  records and every  diffirent fields?

Thank you very much...

Sincerely,

Marc Maurice
