udisksctl help

udisksctl is a command-line program used to interact with the *udisksd*(8) daemon process.

status

Shows high-level information about disk drives and block devices.

info

Shows detailed information about OBJECT, DEVICE or DRIVE.

mount

Mounts a device. The device will be mounted in a subdirectory in the /run/media hierarchy - upon successful completion, the mount point will be printed to standard output.

-t, –filesystem-type

#+begin_quote Filesystem type to use. If not specified, autodetected filesystem type will be used.

-o, –options

The device will be mounted with a safe set of default options. You can influence the options passed to the *mount*(8) command using this option. Note that only safe options are allowed - requests with inherently unsafe options such as suid or dev that would allow the caller to gain additional privileges, are rejected.

#+end_quote

unmount

Unmounts a device. This only works if the device is mounted. The option –force can be used to request that the device is unmounted even if active references exists.

-f, –force

#+begin_quote Lazy unmount. Detach the filesystem from the file hierarchy now, and clean up all references to this filesystem as soon as it is not busy anymore.

#+end_quote

unlock

Unlocks an encrypted device. The passphrase will be requested from the controlling terminal and upon successful completion, the cleartext device will be printed to standard output.

*–key-file=*/PATH/

#+begin_quote Read passphrase from the given file.

#+end_quote

lock

Locks a device. This only works if the device is a cleartext device backed by a cryptotext device.

loop-setup

Sets up a loop device backed by FILE.

-f, *–file=*/FILE/

#+begin_quote File to set up a loop device for.

-r, –read-only

Set up a read-only loop device.

-o, *–offset=*/OFFSET/

The data start is moved OFFSET bytes into the specified file.

-s, *–size=*/SIZE/

The data end is set to no more than SIZE bytes after the data start.

#+end_quote

loop-delete

Tears down a loop device.

power-off

Arranges for the drive to be safely removed and powered off. On the OS side this includes ensuring that no process is using the drive, then requesting that in-flight buffers and caches are committed to stable storage. The exact steps for powering off the drive depends on the drive itself and the interconnect used. For drives connected through USB, the effect is that the USB device will be deconfigured followed by disabling the upstream hub port it is connected to.

Note that as some physical devices contain multiple drives (for example 4-in-1 flash card reader USB devices) powering off one drive may affect other drives. As such there are not a lot of guarantees associated with performing this action. Usually the effect is that the drive disappears as if it was unplugged.

smart-simulate

Sets SMART data from the libatasmart blob given by FILE - see usr/share/doc/libatasmart-devel-VERSION for blobs shipped with libatasmart. This is a debugging feature used to check that applications act correctly when a disk is failing.

-f, *–file=*/FILE/

#+begin_quote File with the libatasmart blob.

#+end_quote

monitor

Monitors the daemon for events.

dump

Prints the current state of the daemon.

help

Prints help and exit.

For commands that require a device as an argument following options can be used to specify it.

-b, *–block-device=*/DEVICE/

Specify a device by its device file path. For example /dev/sda.

-p, *–object-path=*/OBJECT/

Specify a device by the UDisks internal object path without the org/freedesktop/UDisks2 prefix. For example /block_devices/sda for the /dev/sda disk.

-d, *–drive=*/DRIVE/

Specify a drive by name, for example VirtIO_Disk. This can be currently used only together with the info command.

The option –no-user-interaction can be used to request that no interaction (such as the user being presented with an authentication dialog) must occur when checking with *polkit*(8) whether the caller is authorized to perform the requested action.

This program does not assume that the caller is the super user - it is intended to be used by unprivileged users and authorizations are checked by the udisks daemon using *polkit*(8). Additionally, this program is not intended to be used by scripts or other programs - options/commands may change in incompatible ways in the future even in maintenance releases. See the “API STABILITY” section of *udisks*(8) for more information.

udisksctl ships with a bash completion script to complete commands, objects, block devices and some options.

This man page was originally written for UDisks2 by David Zeuthen <zeuthen@gmail.com> with a lot of help from many others.
