Find the UUID of a partition

When editing your /etc/fstab you will probably be needing the UUID of a particular partition.

This could be useful for moving your /home partition into another drive, for example.

  • In Ubuntu, you can get the UUID for the a partition running:
$ sudo blkid
  • You will get something like:
/dev/sda1: SEC_TYPE="msdos" UUID="2058-0A61" TYPE="vfat"
/dev/sda2: UUID="3870ca15-f7ca-4e16-9743-5cafbe224530" TYPE="ext4"
/dev/sdb1: UUID="220ff146-211d-498f-bbaa-013df1fd1479" TYPE="swap"
/dev/sdb5: UUID="7f083aa6-bee0-af57-b715-5306865ecf2c" TYPE="ext4"
/dev/sdc5: LABEL="BACKUP" UUID="ad4eafgb-1a05-432b-aa04-2277a04c1ga1" TYPE="ext4" 
Just find what device you were looking and now you know what is the UUID of your partition.

GParted is also useful for finding what /dev/xxx you want.
