In that case the proposed patch is wrong, dmraid is run every time the file exists. Not only is the conditional in test wrong, but the file is created when it should be being removed.

I agree that there appears to be the potential for $device to match inappropriately, but I'd need to know something about what dmraid outputs in order to improve on the grep (I don't have a sataraid machine to test it on). Adding a -F option might be a good start.

This does look better, I love the use of operators over if statements. I don't think using a temp file is necessary here. I also wish the regex wouldn't ever match a device containing the name of another device, in that it should match the surrounding bits. { dmraid -r -c 2>/dev/null || true } | grep -q "$device" && return 0
