NAME
modinfo - Show information about a Linux Kernel module SYNOPSIS
modinfo [-0] [-F field] [-k kernel] [modulename|filename...] modinfo -V modinfo -h DESCRIPTION
modinfo extracts information from the Linux Kernel modules given on the command line. If the module name is not a filename, then the /lib/modules/version directory is searched, as is also done by modprobe(8) when loading kernel modules. modinfo by default lists each attribute of the module in form fieldname : value, for easy reading. The filename is listed the same way (although it's not really an attribute). This version of modinfo can understand modules of any Linux Kernel architecture. OPTIONS
-V, --version Print the modinfo version. -F, --field Only print this field value, one per line. This is most useful for scripts. Field names are case-insensitive. Common fields (which may not be in every module) include author, description, license, parm, depends, and alias. There are often multiple parm, alias and depends fields. The special field filename lists the filename of the module. -b basedir, --basedir basedir Root directory for modules, / by default. -k kernel Provide information about a kernel other than the running one. This is particularly useful for distributions needing to extract information from a newly installed (but not yet running) set of kernel modules. For example, you wish to find which firmware files are needed by various modules in a new kernel for which you must make an initrd/initramfs image prior to booting. -0, --null Use the ASCII zero character to separate field values, instead of a new line. This is useful for scripts, since a new line can theoretically appear inside a field. -a --author, -d --description, -l --license, -p --parameters, -n --filename These are shortcuts for the --field flag's author, description, license, parm and filename arguments, to ease the transition from the old modutils modinfo.

NAME
modinfo - display information about a kernel module SYNOPSIS
modinfo [ options ] <module_file> DESCRIPTION
The modinfo utility examines the object file module_file associated with a kernel module and displays any information that it can glean. OPTIONS -a, --author Display the module's author. -d, --description Display the module's description. -fformat_string, --format format_string Let the user specify an arbitrary format string which can extract values from the ELF section in module_file which contains the mod- ule information. Replacements consist of a percent sign followed by a tag name in curly braces. A tagname of %{filename} is always supported, even if the module has no modinfo section. %{kernel_version} shows the version of the kernel the module was compiled for. %{using_checksums} expands to 1 is the module has versioned symbols and to 0 or <none> otherwise. A tagname of %{parm} is special: the format string line is repeated for each known module parameter (which may be zero times) and %{parm} is then replaced by descriptions of module parameters (one parameter on each repeated line). Alternatively, %a, %d, %l, %n and %p can be used instead of %{author}, %{description}, %{filename}, %{license} and %{parm}, respec- tively. -h, --help Display a summary of options and immediately exit. -l, --license Display the module's license. -n, --filename Display the module's filename. -p, --parameters Display the typed parameters that a module may support. -V, --version Display the version of modinfo. If no options are supplied, the default is filename, description, author, license and parameters. SEE ALSO
