modinfo(8) modinfo(8)

NAME
modinfo -- program to 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 done by modprobe(8).

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. Note BACKWARDS COMPATIBILITY below: you might be
printing the version of modinfo.old.

-F --field
Only print this field value, one per line. This is most useful for scripts.
Field names are case-insenitive. Common fields (which may not be in every mod-
ule) include author, description, license, param, depends, and alias. There are
often multiple param, alias and depends fields. The special field file-
name lists the filename of the module.

-k kernel Provide information about a kernel other than the running one. This is particu-
larly 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 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 -d -l -p -n
These are shortcuts for author, description, license. param and filename
respectively, to ease the transition from the old modutils modinfo.

BACKWARDS COMPATIBILITY
This version of modinfo is for kernel modules 2.5.48 and above. If it detects a kernel
with support for old-style modules, it will attempt to run modprobe.old in its place, so
it is completely transparent to the user.

Note that the output of this version of modinfo is simpler and more regular than the older
version: scripts attempting to use the default output may get confused with complex
fields.

You can force the new modinfo to always be used, by setting the NEW_MODINFO environ-
ment variable.
