What command would rebuild the ld.so.cache file?
ldconfig creates the necessary links and cache 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
(/lib and /usr/lib). The cache is used by the run-time linker, ld.so or ld-linux.so. ldconfig checks the
header and file names of the libraries it encounters when determining which versions should have
their links updated.
