 ## module-init-tools
 
 Name of a predecessor set of tools.
 
-## package version
-
-From any of the commands, `--version`:
-
-    modinfo --version
-
-Package that provides utilities
-
-## lsmod
-
-List loaded kernel modules.
-
-Info is taken from `/proc/modules`
-
-    lsmod
-
-Sample output:
-
-    cfg80211              175574  2 rtlwifi,mac80211
-    ^^^^^^^^              ^^^^^^  ^ ^^^^^^^,^^^^^^^^
-    1                     2       3 4       5
-
-1.  Name.
-
-2.  Size.
-
-3.  Number of running instances.
-
-	If negative, TODO
-
-4.  Depends on 1.
-
-5.  Depends on 2.
-
-To get more info:
-
-    cat /proc/modules
-
-Also contains two more columns:
-
-- status: Live, Loading or Unloading
-- memory offset: 0x129b0000
-
-## modinfo
-
-Get info about a module by filename or by module name:
-
-    modinfo ./a.ko
-    modinfo a
-
-TODO must take a `.ko` file?
-
-## insmod
-
-    sudo insmod hello.ko
-
-Loads the module.
-
-Does not check for dependencies.
-
-## rmmod
-
-Remove a module. Takes either the module name or the `.ko` file:
-
-    sudo rmmod hello
-    sudo rmmod ./hello.ko
-
 ## modprobe
 
-Vs `insmod`:

-- <https://stackoverflow.com/questions/22891705/whats-the-difference-between-insmod-and-modprobe>
-
-List available modules relative path to `/lib/modules/$KERNEL_VERSION/`:
-
-    sudo modprobe -l
-
-Load the module:
-
-    sudo modprobe $m
-
-Checks for dependencies.
-
 Load module under different name to avoid conflicts:
 
     sudo modprobe vmhgfs -o vm_hgfs
-
-Remove module:
-
-    sudo modprobe -r $m
-
-Check if dependencies are OK:
-
-    sudo depmod -a
-
-Get info about given `.ko` module file:
-
-    m=a
-    sudo rmmod $m
