Final answer: Among the given options, the rpm command used to display which RPM package a file was installed from is 'rpm -qf'.

Answer:

Among the provided options, the correct RPM command to display which RPM package a file was installed from is 'rpm -qf'. This command queries the RPM database to identify the package that installed a specific file.

When it comes to managing packages on a Linux system, understanding RPM commands is essential. One common task is identifying the source package of a specific file. In this case, using the 'rpm -qf' command is the most effective approach.

The 'rpm -qf' command queries the RPM database and retrieves information about the package that installed a particular file. This is useful when you need to trace back the origin of a file on your system and understand which package it belongs to.

It's important to note that each RPM command option serves a different purpose. For instance, 'rpm -qp' is used to query an uninstalled package, 'rpm -qa' lists all installed packages, 'rpm -qi' provides detailed information about an installed package, and 'rpm -ql' lists the files contained in an installed package.

By utilizing the correct RPM command based on your specific requirements, you can efficiently manage packages and troubleshoot issues related to package installations on a Linux system.
