Or another way I think is easier: run /sbin/blkid which will tell you all of the info at once, such as: /dev/sda1: LABEL="boot" UUID="a3193af5-35e1-4908-bfbd-928e8841ead3" TYPE="ext2" /dev/sda2: LABEL="root" UUID="feaa6b06-5935-491d-9aef-fe1415c380b6" TYPE="ext4" /dev/sda3: LABEL="swap" UUID="da4437c5-6f19-409a-a71a-ee63be6ef2e5" TYPE="swap" /dev/sda4: LABEL="home" UUID="145fb951-6f01-4cff-b221-278b72c0604f" TYPE="ext4" It also tells you the RAID member uuid and sub_uuid for your RAID partitions, and more (man blkid).
