6       udisks - udisks command line tool
7

SYNOPSIS

9       udisks [OPTIONS]
10

DESCRIPTION

12       udisks is a simple command line client for the udisks(7) system bus
13       service.
14

OPTIONS

16       --dump
17           Dump all information about all devices. Please include this when
18           filing bugs.
19
20       --enumerate
21           Lists all object paths of devices know to the daemon.
22
23       --enumerate-device-files
24           Lists all device files of devices know to the daemon.
25
26       --monitor
27           Connect to the daemon and print a line every time an event happens.
28
29       --monitor-detail
30           Like --monitor but prints the full details of the device whenever
31           an event happens.
32
33       --show-info device_file
34           Shows information about device_file.
35
36       --inhibit-polling device_file [-- program arg ...]
37           Inhibits polling on device_file. If no program is given, polling is
38           inhibited until Ctrl+C is pressed. Otherwise the program is spawned
39           and the polling is only inhibited until the program terminates.
40
41       --poll-for-media device_file
42           Polls device_file to perform media detection.
43
44       --inhibit-all-polling [-- program arg ...]
45           Inhibits polling on all devices. If no program is given, polling is
46           inhibited until Ctrl+C is pressed. Otherwise the program is spawned
47           and the polling is only inhibited until the program terminates.
48
49       --mount device_file [--mount-fstype fstype] [--mount-options options]
50           Mounts the device represented by device_file using the file system
51           fstype and a comma-separated list of options.
52
53       --unmount device_file [--unmount-options options]
54           Unmounts the device represented by device_file using a
55           comma-separated list of options.
56
57       --detach device_file [--detach-options options]
58           Detaches (e.g. powering down the physical port the device is
59           connected to) the device represented by device_file using a
60           comma-separated list of options.
61
62       --ata-smart-refresh device_file [--ata-smart-wakeup]
63           Refreshes ATA SMART data for device_file. If the disk is sleeping
64           it will not be woken up unless --ata-smart-wakeup is passed. will
65           be used.
66
67       --ata-smart-refresh device_file --ata-smart-simulate blob
68           Read ATA SMART data from blob for device_file. This can only be
69           done by the super user and is typically used for testing that
70           clients relying on the ATA SMART data provided by udisks behave
71           correctly. The libatasmart git repository at
72           http://git.0pointer.de/?p=libatasmart.git;a=summary contains a
73           collection of blobs from failing disks.
74
75       --inhibit [-- program arg ...]
76           Inhibits clients from invoking methods on the daemon that require
77           authorization (all methods will return the
78           org.freedesktop.UDisks.Error.Inhibited error) if the caller is not
79           the super user. This is typically used by OS installers and other
80           programs that expects full control of the system, specifically to
81           avoid automounting devices. Only the super user can do this.
82
83           If no program is given, the daemon is inhibited until Ctrl+C is
84           pressed. Otherwise the program is spawned and the daemon is only
85           inhibited until the program terminates.
86
87       --set-spindown device_file --spindown-timeout seconds
88       [-- program arg ...]
89           Configures disk spindown timeout on device_file to seconds. See the
90           section called “SPINNING DOWN DISKS” for important information
91           before using this option.
92
93           If no program is given, the spindown time will be used until Ctrl+C
94           is pressed. Otherwise the program is spawned and the the spindown
95           timeout will only be used until the program terminates.
96
97       --set-spindown-all --spindown-timeout seconds [-- program arg ...]
98           Configures disk spindown timeout on all disks that can be spun down
99           to seconds. See the section called “SPINNING DOWN DISKS” for
100           important information before using this option.
101
102           If no program is given, the spindown time will be used until Ctrl+C
103           is pressed. Otherwise the program is spawned and the the spindown
104           timeout will only be used until the program terminates.
105
106       --help
107           Show help options.

SPINNING DOWN DISKS

110       Caution should be exercised when configuring disk spin down timeouts.
111
112       Note that every time a disk is spun down, the “start-stop-count” ATA
113       SMART attribute will increase by 1 and most disks are only good for a
114       limited number (typically 50,000 but it varies by manufacturer and
115       model). In addition, the drive may take as long as 30 seconds to
116       respond to subsequent disk access – most drives are typically faster,
117       see the “spin-up-time” ATA SMART attribute.
118
119       On the other hand, cautious use (e.g. using conservative timeouts) of
120       the ability to spin down disks, can be a good way to trade power
121       consumption (typically 8 vs 1 Watts for 3.5" drives) and heat emission
122       for a slightly higher latency.
