Which command searches a repository for files provided by a specific package?

• A. yum provides /var/www/html
• B. yum whatprovides /var/www/html
• C. rpm -qf /var/www/html
• D. yum search html

Answer: (A)

This tests how to map a specific file path to the package that provides it by checking repository metadata. The command yum provides /var/www/html asks the enabled repositories to find any package that includes that exact file in its payload. It returns the package name (and version) that would supply that file, which is exactly what you need when you want to install a package to obtain a particular file.

Other options don’t fit as well: yum whatprovides /var/www/html is basically the same idea in many environments, but the standard form used to locate a file in repos is yum provides. rpm -qf /var/www/html looks up which installed package currently owns the file on your system, not which package would supply it from the repositories. yum search html scans package names or descriptions for the string “html,” not the actual file path.
