lsmod - Unix, Linux Command

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
