KENV(1) BSD General Commands Manual KENV(1)NAMEkenv — dump or modify the kernel environment
SYNOPSISkenv [-hq]
kenv [-q] variable[=value]
kenv [-q] -u variable
DESCRIPTION
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 -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.
Variables can be added to the kernel environment using the
/boot/loader.conf file, or also statically compiled into the kernel using
the statement
env filename
in the kernel config file. The file can contain lines of the form
name = value # this is a comment
where whitespace around name and '=', and everything after a '#' charac‐
ter, are ignored. Almost any printable character except '=' is accept‐
able as part of a name. Quotes are optional and necessary only if the
value contains whitespace.
