usage make sure fsanitize=address is off but the -g is on

valgrind --leak-check=full \
         --show-leak-kinds=all \
         --track-origins=yes \
         --log-file=valgrind-out.txt \
         ./minishell

installation 

apt install valgrind

will add it to the docker image, so we can more easily test, maybe the option to launch the leaks check with a makefile rule
