Basic usage of udisks

  • 772

I'm on Ubuntu Mate 16.04. I would like someone to give me a short introduction to the basic usage of the udisks utility on Linux systems. Specifically, I would like to know how to properly mount and unmount an external USB drive.

    To see connected devices do

    lsblk

    Identify the device you want to mount or unmount. USB devices will mount in /media so after you connect them you can identify them by their mountpoints. We can see the mounted device here is /dev/sda1

    NAME         MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda            8:0    1 15.2G  0 disk 
└─sda1         8:1    1 15.2G  0 part /media/zanna/4C45-110F

    to unmount this device:

    udisksctl unmount -b /dev/sda1

    -b stands for block device. After entering this command lsblk shows:

    NAME         MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda            8:0    1 15.2G  0 disk 
└─sda1         8:1    1 15.2G  0 part

    Now it's safe to remove. To re-mount it:

    udisksctl mount -b /dev/sda1

    For general help type udisksctl help and for help on each command, type it and add --help for example:

    udisksctl info --help

    For information about my root partition I would type

    udisksctl info -b /dev/mmcblk0p2

    For more information type info udisksctl
