6 modinfo - Show information about a Linux Kernel module

13 modinfo -h
14
16 modinfo extracts information from the Linux Kernel modules given on the
17 command line. If the module name is not a filename, then the
18 /lib/modules/version directory is searched, as is also done by
19 modprobe(8) when loading kernel modules.
20
21 modinfo by default lists each attribute of the module in form fieldname
22 : value, for easy reading. The filename is listed the same way
23 (although it's not really an attribute).
24
25 This version of modinfo can understand modules of any Linux Kernel
26 architecture.
27
29 -V, --version
30 Print the modinfo version.
31
32 -F, --field
33 Only print this field value, one per line. This is most useful for
34 scripts. Field names are case-insensitive. Common fields (which may
35 not be in every module) include author, description, license, parm,
36 depends, and alias. There are often multiple parm, alias and
37 depends fields. The special field filename lists the filename of
38 the module.
39
40 -b basedir, --basedir basedir
41 Root directory for modules, / by default.
42
43 -k kernel
44 Provide information about a kernel other than the running one. This
45 is particularly useful for distributions needing to extract
46 information from a newly installed (but not yet running) set of
47 kernel modules. For example, you wish to find which firmware files
48 are needed by various modules in a new kernel for which you must
49 make an initrd/initramfs image prior to booting.
50
51 -0, --null
52 Use the ASCII zero character to separate field values, instead of a
53 new line. This is useful for scripts, since a new line can
54 theoretically appear inside a field.
55
56 -a --author, -d --description, -l --license, -p --parameters, -n
57 --filename
58 These are shortcuts for the --field flag's author, description,
59 license, parm and filename arguments, to ease the transition from
60 the old modutils modinfo.
