When I mdconfig a device and _do not_ specify a particular numbered md
device (with the -u flag), it just chooses an unused device number for
me. Which makes me happy.
Unfortunately, mdconfig chooses the next available device, from the
highest device currently in use, regardless of

I've written a script to check apache to make sure it's running *and*
logging. One of the variables I create is named DATEHOUR, and it's created
by parsing the output of date in such a way that all I get is the hour

To get the date in the right format you could simply use
date +%H

This'll strip the 0, while leaving other numbers intact:

$ echo ${X#0}

able to walk away and automatically shut down the process without
corrupting the wav file. I know the tape duration so I was planning to
use the following script. I'd appreciate a better or more refined
