modinfo

modinfo

The modinfo command in Linux is used to display information about kernel modules. Kernel modules are pieces of software that can be loaded into the Linux kernel to add new features or functionality.

The syntax of the modinfo command is as follows:

modinfo [options] module-name

The module-name argument specifies the name of the kernel module that you want to get information about.

The options argument specifies additional options for getting information about the kernel module. The most common options are as follows:

• -F: Display the value of a specific field.

• -k: Display the kernel version that the module was built for.

• -n: Display the name of the module.

• -p: Display the path to the module file.

For example, the following command displays the name, version, and description of the kernel module module-name:

modinfo module-name

The modinfo command is a useful tool for getting information about kernel modules. It can be used to see what kernel modules are loaded, to get information about a specific kernel module, or to troubleshoot kernel module problems.

Here are some additional things to keep in mind about the modinfo command:

• The modinfo command can only be used to get information about kernel modules that are loaded into the Linux kernel.

• The modinfo command cannot be used to get information about kernel modules that are not loaded into the Linux kernel.

• The modinfo command can be used to get information about kernel modules that are installed on your system, even if they are not currently loaded.

It is important to be aware of these limitations when using the modinfo command, so that you do not get confused by the output or accidentally get information about a kernel module that is not relevant to your system.
