+  $ apt-file search filename <package_name>
+  
+  # CentOS/RHEL
+  $ rpm -qf <package_name>
+  $ yum whatprovides '*target/filename' <package_name>
 
 話說套件管理的指令也不算少，凍仁強烈建議大家使用 aptitude 及 yum 來管理套件，其最棒的是它們會自行處理套件間的相依性，可減輕不少負擔。至於參數的部份，請先牢記 search, install, update, upgrade 和 remove。相信到這裡我們已可完成大部份的事情了。
