The modinfo command line tool is used in Linux systems to display information about kernel module files. It provides details about the modules loaded in the system, helping users understand their functionalities and dependencies.
When executed, modinfo displays information such as module name, filename, description, author, license, vermagic, and various other attributes included in the module metadata. This data can be useful for troubleshooting, checking module versions, and finding relevant documentation.
Modinfo can also retrieve information related to the alias and options used for a particular module, making it easier to configure and customize module behavior. Additionally, it provides a list of other modules that are used by or dependent on the given module, enabling users to comprehend module interdependencies.
By examining the modinfo output, administrators and users can gain insights into the modules present in the system, understand their purpose, and manage them effectively. Whether it's inspecting modules or resolving module-related issues, modinfo serves as a valuable tool for Linux system maintenance.
