- ldd — check which libraries a specific program file is using
- ldconfig — rebuilds the library cache after adding or removing libraries
- includes both changing the content of the library directories and adding/removing directories
- [ -v ] displays verbose information (summaries of what’s going on)
- [ -N ] causes ldconfig to not perform its primary duty of updating the library cache
- [ -n ] causes ldconfig to update the links contained in the directories specified
- [ -X ] is the opposite of -N causing ldconfig to update the cache but not manage links
- [ -f + conffile ] change the configuration file from /etc/ld.so.conf to specified conffile
- [ -C + cachefile ] change the cache file that ldconfig creates
- [ -r + dir ] tells ldconfig to treat dir as if it were the root directory
- [ -p ] causes ldconfig to display the current cache
