In computing, ldconfig is a shell command used for creating and updating symbolic links and the cache for shared libraries. It is found in most Linux distributions and FreeBSD, and it is part of the glibc package. ldconfig works by searching for .so files in directories specified in the /etc/ld.so.conf file, the trusted directories ( /lib and /usr/lib , or /lib64 and /usr/lib64 on multilib systems), and any directories specified on the command line. The generated binary cache file, /etc/ld.so.cache , is used by ld.so to speed up library lookup at runtime. ldconfig can be compared to regsvr32 in Windows and ReactOS, and to dyld in macOS.

( -N is implied, so the cache won't be rebuilt) -N – skips rebuilding the cache -v , --verbose – runs in verbose mode; prints version number, scanned directories, and all created links -V , --version – prints the version number -X – skips updating links -p – prints the current cache -r ROOT – specify a directory as the root directory Source:
