For first run, simply use make:
make
To re-parse the memory.txt file, you can run it again. This is useful for
feeding the data into sources other than the Terminal:
make | code -
To regenerate the memory dump completely, clean and then run again:
make clean && make
Some binaries are optimized and stripped of debugging symbols. This will expose fewer entries in the memory dump. You can do this as well by making an optimized build:
make app_optimized && make
For reading the memory dump directly, consider using a hex viewing tool such as HexFiend (Apple Store link).
