KENV(1)			FreeBSD	General	Commands Manual		       KENV(1)

NAME
     kenv -- dump or modify the	kernel environment

SYNOPSIS
     kenv [-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.
