Toy implementation of nm & otool bsd commands. The general idea was to learn how a binary file work and how to parse it properly.
These tools only support mach-o files.
Just run make, it will generate ft_nm and ft_otool.
You can test nm with some system binaries by launching make test_all. It will assert there is no output difference between my implementation and the current system implementation.
Tests will take some time to complete!
./ft_nm -uUrpj [FILE ...]
-u Display only undefined symbols.
-U Don't display undefined symbols.
-r Sort in reverse order.
-p Don't sort; display in symbol-table order.
-j Just display the symbol names (no value or type).
./ft_otool -td [FILE ...]
-t Display the contents of the (__TEXT,__text) section.
-d Display the contents of the (__DATA,__data) section.
