Where are the hex files compiled by Arduino?

Question

Where does the Arduino IDE save the binaries on Mac OS X?

Answer 1

The arduino web page http://arduino.cc/en/Hacking/BuildProcess described

During a "Verify" the .hex file is written to /tmp (on Mac and Linux) or \Documents and Settings\\Local Settings\Temp (on Windows)

I am using fedora19 64bit, and when i check my /tmp the build directory created is /tmp/build8102....tmp/
