From the Ld.so package we're using the ldconfig and ldd programs.

A.30.2. Description

A.30.2.1. ldconfig

ldconfig creates the necessary links and cache (for use by the run-time linker, ld.so) to the most recent shared libraries found in the directories specified on the command line, in the file /etc/ld.so.conf, and in the trusted directories (/usr/lib and /lib). ldconfig checks the header and file names of the libraries it encounters when determining which versions should have their links updated.

A.30.2.2. ldd

ldd prints the shared libraries required by each program or shared library specified on the command line.
