I testify with my own experience that after I ran a Shell script for over 2 days with thousands of test cases, valgrind rewarded me no bugs. So, if you are a student struggling to finish a class project the night before deadline, use not valgrind if not required.

What, then, is the substitute? The answer is flawfinder! Within a minute of run on the same software project, it spit out 778 potential bugs. Obviously, this tool has a high false positivity rate. But it is extremely time-saving and provides critical information for you to decide the severity of the bugs.

Find the official website here. To download and install on MacBook, simply run

pip install flawfinder

To analyze a project, execute

flawfinder <directory/to/project>
