sysctl with regex?

[Andrew Brampton]

Today I was writing a script to read all the dev.cpu.?.temperature
sysctl OIDs. I was parsing them using a simple grep, but it occurred
to me it might be better if sysctl supported some form of regexp. For
example instead of typing:
sysctl -a | grep dev.cpu.*.temperature

I could write:
sysctl dev.cpu.*.temperature

which would display all the OIDs that match dev.cpu.*.temperature.
This is better than grep because when I issue a "sysctl -a" the
program retrieves many variables that I am not interested in (which
later get filtered by grep). This would in a way be similar to: sysctl
dev.cpu

which lists all the OIDs under dev.cpu. Is this a feature people would
find useful? Or would I be optimising a problem that doesn't exist?

Thanks for any input
