modinfo — program to show information about a Linux Kernel module
modinfo [-0] [-F field] [modulename|filename ...]
modinfo extracts information from the Linux Kernel modules given on the
command line. If the module name is not a filename, then the /lib/mod-
ules/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
Print the modinfo version. Note BACKWARDS COMPATIBILITY
below: you might be printing the version of modinfo.old.
Only print this field value, one per line. This is most use-
ful for scripts. Field names are case-insenitive. Common
fields (which may not be in every module) include author,
description, license, param, depends, and alias. There are
often multiple param, alias and depends fields. The
special field filename lists the filename of the mod-
-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.
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
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 environment variable.
