KENV(1) BSD General Commands Manual KENV(1) NAME kenv -- dump or modify the kernel environment SYNOPSIS kenv [-hNq] kenv [-qv] variable[=value] kenv [-q] -u variable DESCRIPTION The kenv utility will dump the kernel environment if invoked without ar- guments. If the -h option is specified, it will limit the report to ker- nel 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, 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.
