kenv - dump or modify the kernel environment

kenv [-hq]
kenv [-q] variable[=value]
kenv [-q] -u variable

The kenv utility will dump the kernel environment if invoked
without arguments. If the -h option is specified, it will limit the
report to kernel probe hints. If an optional variable name is speci
fied, kenv will
only report that value. If the -u option is specified, kenv
will delete the given environment variable. If the environment variable
is followed
by an optional value, kenv will set the environment variable
to this value.
If the -q option is set, warnings normally printed as a re
sult of being unable to perform the requested operation will be sup
pressed.
