ldconfig

Configure symlinks and cache for shared library dependencies. More information: https://manned.org/ldconfig.

• Update symlinks and rebuild the cache (usually run when a new library is installed):
  sudo ldconfig
• Update the symlinks for a given directory:
  sudo ldconfig -n {{path/to/directory}}
• Print the libraries in the cache and check whether a given library is present:
  ldconfig -p | grep {{library_name}}
