  • Tip: Using UUID for mounting disks, the convenient way

    Posted on

    Hi everyone,

    I just wanted to share a quick tip I just stumbled upon searching for a way to efficiently use the UUID when mounting disks.

    Normally I would just use the blkid command to get the UUID of a particular disk.

    blkid /dev/vda1
    

    This involved, either copying the UUID, when possible, or typing it manually. Which is obvious error-prone .

    Now I use the command blkid with some additional options

    blkid /dev/vda1 -sUUID -ovalue
    

    inside the mount command, as follows:

    mount UUID=$(blkid /dev/vda1 -sUUID -ovalue) /mnt
    

    Additional: When using vim one could use :r(ead)! from command mode, when editing /etc/fstab, for example, to insert UUID into file.

    :r!blkid /dev/vda1 -sUUID -ovalue
    

    Note: Swap all occurrences of /dev/vda1 and /mnt for your own values. :-)

    Regards,
    Peter
