MODINFO(8)MODINFO(8)NAMEmodinfo - program to show information about a Linux Kernel module
SYNOPSISmodinfo [ -0 ] [ -F field ] [ -k kernel ] [ modulename|filename... ]
modinfo-V
modinfo-h
DESCRIPTIONmodinfo 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
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 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 module.
-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 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 modu‐
tils 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 environment variable.
