MODINFO(8)                       modinfo                      MODINFO(8)

NAME         top

       modinfo - Show information about a Linux Kernel module

SYNOPSIS         top

       modinfo [-0] [-F field] [-k kernel] [modulename|filename...]

       modinfo -V

       modinfo -h

DESCRIPTION         top

       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 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 architecture.

OPTIONS         top

       -V, --version
           Print the modinfo version.

       -F, --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 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/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 theoretically appear inside a field.

       -a --author, -d --description, -l --license, -p --parameters, -n
           These are shortcuts for the --field flag's author,
           description, license, parm and filename arguments, to ease
           the transition from the old modutils modinfo.
