DESCRIPTION

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

COMMANDS

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

info
Shows detailed information about OBJECT or DEVICE.

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

The device will be mounted with a safe set of default options. You can influence the
options passed to the mount(8) command with --options. 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.

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.

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.

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.

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.

monitor
Monitors the daemon for events.

dump
Prints the current state of the daemon.

help
Prints help and exit.

COMMON OPTIONS

       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.

AUDIENCE

       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.

BASH COMPLETION

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