Find device name from UUID

1224631063000

Now that most distros, Fedora in particular insist that you use UUIDs instead of device names in the /etc/fstab file, most of us know at least two different commands which can locate the UUID for a given partition. (What's that you don't know even one? try blkid). What if you want to do opposite; find the device name when the UUID is known? One solution is to just type 'df' and compare the mount points with the contents of the /etc/fstab - that will tell you what the device name is if your partition has been mounted. It will not work for unmounted partitions and  the swap. When that  happens you can try:

ls -l /dev/disk/by-uuid

On my computer it produces something like this:
lrwxrwxrwx 1 root root 10 2008-10-17 15:53 01b06f7e-9dab-4ff0-9d05-b2f7d83b0cab -> ../../sdb1 lrwxrwxrwx 1 root root 10 2008-10-17 15:53 1d5dd1c9-d924-4640-912f-d7f463293625 -> ../../sda1 lrwxrwxrwx 1 root root 10 2008-10-17 15:53 2ccc4b5c-cac9-4479-9c37-8f891ea18db8 -> ../../sdb4 lrwxrwxrwx 1 root root 10 2008-10-17 15:53 65234e85-5d02-47f2-aadc-da5232fdaa0b -> ../../sda5 lrwxrwxrwx 1 root root 10 2008-10-17 15:53 7d745a84-f09f-43cd-b761-e94abdb72fe6 -> ../../sda4 lrwxrwxrwx 1 root root 10 2008-10-17 15:53 85732ed8-4529-4884-9cc3-f03d5f08d60a -> ../../sda6 lrwxrwxrwx 1 root root 10 2008-10-17 15:53 ace70227-ab7f-47f2-b4cd-7fc6d67df3f8 -> ../../sdb5 lrwxrwxrwx 1 root root 10 2008-10-17 15:53 bf695d17-a57c-4f3a-9d55-65fa43c7112a -> ../../sda2 lrwxrwxrwx 1 root root 10 2008-10-17 15:53 c0d24b7e-20ce-4a7c-b2c9-7dc9161bbfc2 -> ../../sdc1 lrwxrwxrwx 1 root root 10 2008-10-17 15:53 cd291369-3ea2-40a7-baff-1b9261941e74 -> ../../sdb3
This listing can be used to find the UUID when the device name is known and vice verce.
