Thanks for the reply. I have a huge file in unix.
As per the file definition, the file is a tab separated file of fields. But I am sure that within some field's I have some new line character.
How should I find a record? It is a huge file. Is there some command?

If your data contains new line chars, its better you write a custom map reduce job and convert the data into a single line removing all unwanted chars in column separator as well just having single new line char per line
