KENV(1)			  BSD General Commands Manual		       KENV(1)

     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 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

     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.

     kenv(2), config(5), loader.conf(5), loader(8)

     The kenv utility appeared in FreeBSD 4.1.1.
