KENV(1) DragonFly General Commands Manual KENV(1)
kenv -- dump or modify the kernel environment
kenv [-qv] 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 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 comment
kenv(2), loader.conf(5), loader(8)
The kenv utility appeared in FreeBSD 4.1.1.
