NAME

lsmod - list loaded modules.

SYNOPSIS

  • lsmod [options]
  • DESCRIPTION

    lsmod shows information about all loaded modules. The format is name, size, use count, list of referring modules. The information displayed is identical to that available from /proc/modules. If the module controls its own unloading via a can_unload routine then the user count displayed by lsmod is always -1, irrespective of the real use count. The module files are with .ko extension.

    EXAMPLES

    Example-1:

    To list Currently Loaded Modules:

    # lsmod

    output:

    # lsmod
