45 udisksctl is a command-line program used to interact with the
46 udisksd(8) daemon process.
47
49 status
50 Shows high-level information about disk drives and block devices.
51
52 info
53 Shows detailed information about OBJECT or DEVICE.
54
55 mount
56 Mounts a device. The device will be mounted in a subdirectory in
57 the /media hierarchy - upon successful completion, the mount point
58 will be printed to standard output.
59
60 The device will be mounted with a safe set of default options. You
61 can influence the options passed to the mount(8) command with
62 --options. Note that only safe options are allowed - requests with
63 inherently unsafe options such as suid or dev that would allow the
64 caller to gain additional privileges, are rejected.
65
66 unmount
67 Unmounts a device. This only works if the device is mounted. The
68 option --force can be used to request that the device is unmounted
69 even if active references exists.
70
71 unlock
72 Unlocks an encrypted device. The passphrase will be requested from
73 the controlling terminal and upon successful completion, the
74 cleartext device will be printed to standard output.
75
76 lock
77 Locks a device. This only works if the device is a cleartext device
78 backed by a cryptotext device.
79
80 loop-setup
81 Sets up a loop device backed by FILE.
82
83 loop-delete
84 Tears down a loop device.
85
86 power-off
87 Arranges for the drive to be safely removed and powered off. On the
88 OS side this includes ensuring that no process is using the drive,
89 then requesting that in-flight buffers and caches are committed to
90 stable storage. The exact steps for powering off the drive depends
91 on the drive itself and the interconnect used. For drives connected
92 through USB, the effect is that the USB device will be deconfigured
93 followed by disabling the upstream hub port it is connected to.
94
95 Note that as some physical devices contain multiple drives (for
96 example 4-in-1 flash card reader USB devices) powering off one
97 drive may affect other drives. As such there are not a lot of
98 guarantees associated with performing this action. Usually the
99 effect is that the drive disappears as if it was unplugged.
100
101 smart-simulate
102 Sets SMART data from the libatasmart blob given by FILE - see
103 /usr/share/doc/libatasmart-devel-VERSION/ for blobs shipped with
104 libatasmart. This is a debugging feature used to check that
105 applications act correctly when a disk is failing.
106
107 monitor
108 Monitors the daemon for events.
109
110 dump
111 Prints the current state of the daemon.
112
113 help
114 Prints help and exit.
115
117 The option --no-user-interaction can be used to request that no
118 interaction (such as the user being presented with an authentication
119 dialog) must occur when checking with polkit(8) whether the caller is
120 authorized to perform the requested action.
121
123 This program does not assume that the caller is the super user - it is
124 intended to be used by unprivileged users and authorizations are
125 checked by the udisks daemon using polkit(8). Additionally, this
126 program is not intended to be used by scripts or other programs -
127 options/commands may change in incompatible ways in the future even in
128 maintenance releases. See the “API STABILITY” section of udisks(8) for
129 more information.
130
132 udisksctl ships with a bash completion script to complete commands,
133 objects, block devices and some options.
