Consider allowing -t to be supplied more than once

[chrishoage]

Currently if supplying multiple -t flags the last one wins and that device is spun down

hd-idle/main.go

Lines 182 to 193 in 44c8db6

	if singleDiskMode {
	if err := spindownDisk(
	disk,
	config.Defaults.CommandType,
	config.Defaults.PowerCondition,
	config.Defaults.Debug,
	); err != nil {
	fmt.Println(err.Error())
	os.Exit(1)
	}
	os.Exit(0)
	}

It would be convenient to be able to specify -t multiple times so that multiple devices could be spun down with out needing to invoke the command multiple times.

example:

sudo hd-idle -t /dev/disk/by-id/ata-HGST_HDN724040ALE640_PK2334PEK4AXTT -t /dev/disk/by-id/ata-HGST_HDN724040ALE640_PK1334PEKDXVTS

if any of the devices fail, exit 1 (even if some succeeded). Print the error.

If all devices succeed, exit 0.

Hi @chrishoage

That makes sense.
Also, in case of any error the command could safely be retried given that spin down a disk is an idempotent operation.

I'll try to find some time to implement it.
