• NAME
  
  modinfo - program to show information about a Linux Kernel module
• SYNOPSIS
  
  
  modinfo [ -0 ] [ -F field ] [ -k kernel ] [ modulename|filename ... ]
  
  modinfo -V
  
  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 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, parm, depends, and alias. There are often multiple parm, 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.  parm and filename respectively, to ease the transition from the old modutils 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.
