Using tesseract-ocr #3.02.02.
The basic usage of tesseract is
tesseract sourc.png result
and result.txt is generated. To get the result text, I have to cat this file.
Is there any options to dump the result in stdout?

You should upgrade to v3.03 where support for stdout was added.
The solution is:
tesseract input.jpg stdout
But you need at least version 3.03
