With avrdude you could do this:
avrdude -p m8 -c avr910 -P /dev/ttyUSB0 -U flash:r:flash.hex:i
This will write the content of the microcontroller to the file flash.hex.

But when compared the contents of flash.hex with your hex file
usally you will get a difference even the content is the same.
So it needs to convert to binary first to compare the two hex files.
