shell scripting question (mdconfig device choosing)

Hello, 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 wheth

Shell scripting question

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 (using awk and cut.) I'm comparing DATEHOUR to LOGHOUR, which represents the
