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

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.
