I'm not sure such a feature is really necessary. What's wrong with this approach? $ sysctl dev.cpu | grep temperature When you need that in a script, there's an even more elegant way to do it: NCPU=`sysctl -n hw.ncpu` OIDS=`jot -w dev.cpu.%d.temperature $NCPU 0` sysctl $OIDS There's no need to use "sysctl -a". After all, the "UNIX way" of doing things is to combine the existing tools instead of duplicate features in many tools. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co.
