MODINFO(8) Linux Module Support MODINFO(8)
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.
