ldd (List Dynamic Dependencies) is a *nix utility that prints the shared libraries required by each program or shared library specified on the command line.[1] It was developed by Roland McGrath and Ulrich Drepper.[2] ldd is a shell script that executes the program given as argument, and shouldn't be used with untrusted binaries.
