Recently when implementing Milliseconds in MySQL Proxy Lua Script I needed to identify what was installed from a given package.
For CentOS
$ sudo yum install -y yum-utils $ repoquery -q -l --plugins lua-socket /usr/lib64/lua/5.1/mime /usr/lib64/lua/5.1/mime/core.so /usr/lib64/lua/5.1/socket /usr/lib64/lua/5.1/socket/core.so /usr/share/doc/lua-socket-2.0.2 /usr/share/doc/lua-socket-2.0.2/LICENSE /usr/share/doc/lua-socket-2.0.2/README /usr/share/doc/lua-socket-2.0.2/dns.html /usr/share/doc/lua-socket-2.0.2/ftp.html /usr/share/doc/lua-socket-2.0.2/http.html /usr/share/doc/lua-socket-2.0.2/index.html /usr/share/doc/lua-socket-2.0.2/installation.html /usr/share/doc/lua-socket-2.0.2/introduction.html /usr/share/doc/lua-socket-2.0.2/ltn12.html /usr/share/doc/lua-socket-2.0.2/luasocket.png /usr/share/doc/lua-socket-2.0.2/mime.html /usr/share/doc/lua-socket-2.0.2/reference.css /usr/share/doc/lua-socket-2.0.2/reference.html /usr/share/doc/lua-socket-2.0.2/smtp.html /usr/share/doc/lua-socket-2.0.2/socket.html /usr/share/doc/lua-socket-2.0.2/tcp.html /usr/share/doc/lua-socket-2.0.2/udp.html /usr/share/doc/lua-socket-2.0.2/url.html /usr/share/lua/5.1/ltn12.lua /usr/share/lua/5.1/mime.lua /usr/share/lua/5.1/socket /usr/share/lua/5.1/socket.lua /usr/share/lua/5.1/socket/ftp.lua /usr/share/lua/5.1/socket/http.lua /usr/share/lua/5.1/socket/smtp.lua /usr/share/lua/5.1/socket/tp.lua /usr/share/lua/5.1/socket/url.lua
