How to see the captured data in file sink

Hi,

I am new to gnu radio and I have a dat file (complex or float) captured
from
file sink which was directly connected USRP.
Can anyone help me with how to see the data in the dat file as i was
trying
with octave but i dont know much about octave too.

Use gnuradio-companion and connect a file source → throttle → scope or
fft sink. http://gnuradio.org/redmine/wiki/1/GNURadioCompanion
