>_ modinfo -F [author|description|license|parm|filename] [kernel_module]
copy

SYNOPSIS

' modinfo 'u modinfo [ -0 ][ -F field ][ -k kernel ][modulename|filename...] ' modinfo-V 'u modinfo-V ' modinfo-h 'u 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/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 (Aqs not really an attribute) .

This version of modinfo can understand modules of any Linux Kernel architecture .

OPTIONS

-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 --filename These are shortcuts for the --field flag (Aqs author, description, license, parm and filename arguments, to ease the transition from the old modutils modinfo .
