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 speci-
fied, kenv will delete the given environment variable. If the environ-
ment variable is followed by an optional value, kenv will set the envi-
ronment 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.
