MODINFO(8) modinfo MODINFO(8)
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/mod-
ules/ 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 ar-
chitecture.
OPTIONS
-V, --version
Print the modinfo version.
-F field, --field=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 informa-
tion from a newly installed (but not yet running) set of kernel mod-
ules. For example, you wish to find which firmware files are needed
by various modules in a new kernel for which you must make an ini-
trd/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 theoreti-
cally appear inside a field.
-a --author, -d --description, -l --license, -p --parameters, -n --file-
name
These are shortcuts for the --field flag's author, description, li-
cense, parm and filename arguments, to ease the transition from the
old modutils modinfo.
-h, --help
Print the help message and exit.
