UNIX Package Managers
Checking Library Files
You can check whether a library file exists (without needing to know which package/package manager provided it) using...
ldconfig -p | grep LibrarynameWithoutAnySuffix
Examples...
ldconfig -p | grep libaio
  libaio.so.1 (libc6,x86-64) => /lib/x86_64-linux-gnu/libaio.so.1
ldconfig -p | grep libnuma
  libnuma.so.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libnuma.so.1
