DESCRIPTION
Thekenv 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 specified, kenv
will only report that value. If the -N option is
specified, kenv will only display variable names and
not their values. 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 result of being unable to perform the requested operation will
be suppressed.
If the -v option is set, the variable name
will be printed out for the environment variable in addition to the value
when kenv is executed with a variable name.
Variables can be added to the kernel environment using the /boot/loader.conf file. The file can contain lines of the form
name = value # this is a
