Overview

The kldunload utility unloads a file which was previously loaded with kldload(8).

The following options are available:

-f

Force the unload. This ignores error returns to MOD_QUIESCE from the module and implies that the module should be unloaded even if it is currently in use. The users are left to cope as best they can.

-v

Be more verbose.

-i id

Unload the file with this ID.

-n name

Unload the file with this name.

name

Unload the file with this name.

Exit status

The kldunload utility exits 0 on success, and >0 if an error occurs.
