NAME

       udisks - udisks command line tool

SYNOPSIS

       udisks [OPTIONS]

DESCRIPTION

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

OPTIONS

       --dump
           Dump all information about all devices. Please include this when filing bugs.

       --enumerate
           Lists all object paths of devices know to the daemon.

       --enumerate-device-files
           Lists all device files of devices know to the daemon.

       --monitor
           Connect to the daemon and print a line every time an event happens.

       --monitor-detail
           Like --monitor but prints the full details of the device whenever an event happens.

       --show-info device_file
           Shows information about device_file.

       --inhibit-polling device_file [-- program arg ...]
           Inhibits polling on device_file. If no program is given, polling is inhibited until
           Ctrl+C is pressed. Otherwise the program is spawned and the polling is only inhibited
           until the program terminates.

       --poll-for-media device_file
           Polls device_file to perform media detection.

       --inhibit-all-polling [-- program arg ...]
           Inhibits polling on all devices. If no program is given, polling is inhibited until
           Ctrl+C is pressed. Otherwise the program is spawned and the polling is only inhibited
           until the program terminates.

       --mount device_file [--mount-fstype fstype] [--mount-options options]
           Mounts the device represented by device_file using the file system fstype and a
           comma-separated list of options.

       --unmount device_file [--unmount-options options]
           Unmounts the device represented by device_file using a comma-separated list of
           options.

       --detach device_file [--detach-options options]
           Detaches (e.g. powering down the physical port the device is connected to) the device
           represented by device_file using a comma-separated list of options.

       --eject device_file [--eject-options options]
           Ejects media from the device represented by device_file using a comma-separated list
           of options.

       --ata-smart-refresh device_file [--ata-smart-wakeup]
           Refreshes ATA SMART data for device_file. If the disk is sleeping it will not be woken
           up unless --ata-smart-wakeup is passed. will be used.

       --ata-smart-refresh device_file --ata-smart-simulate blob
           Read ATA SMART data from blob for device_file. This can only be done by the super user
           and is typically used for testing that clients relying on the ATA SMART data provided
           by udisks behave correctly. The libatasmart git repository at
           http://git.0pointer.de/?p=libatasmart.git;a=summary contains a collection of blobs
           from failing disks.

       --inhibit [-- program arg ...]
           Inhibits clients from invoking methods on the daemon that require authorization (all
           methods will return the org.freedesktop.UDisks.Error.Inhibited error) if the caller is
           not the super user. This is typically used by OS installers and other programs that
           expects full control of the system, specifically to avoid automounting devices. Only
           the super user can do this.

           If no program is given, the daemon is inhibited until Ctrl+C is pressed. Otherwise the
           program is spawned and the daemon is only inhibited until the program terminates.

       --set-spindown device_file --spindown-timeout seconds [-- program arg ...]
           Configures disk spindown timeout on device_file to seconds. See the section called
           “SPINNING DOWN DISKS” for important information before using this option.

           If no program is given, the spindown time will be used until Ctrl+C is pressed.
           Otherwise the program is spawned and the the spindown timeout will only be used until
           the program terminates.

       --set-spindown-all --spindown-timeout seconds [-- program arg ...]
           Configures disk spindown timeout on all disks that can be spun down to seconds. See
           the section called “SPINNING DOWN DISKS” for important information before using this
           option.

           If no program is given, the spindown time will be used until Ctrl+C is pressed.
           Otherwise the program is spawned and the the spindown timeout will only be used until
           the program terminates.

       --help
           Show help options.

SPINNING DOWN DISKS

       Caution should be exercised when configuring disk spin down timeouts.

       Note that every time a disk is spun down, the “start-stop-count” ATA SMART attribute will
       increase by 1 and most disks are only good for a limited number (typically 50,000 but it
       varies by manufacturer and model). In addition, the drive may take as long as 30 seconds
       to respond to subsequent disk access – most drives are typically faster, see the
       “spin-up-time” ATA SMART attribute.

       On the other hand, cautious use (e.g. using conservative timeouts) of the ability to spin
       down disks, can be a good way to trade power consumption (typically 8 vs 1 Watts for 3.5"
       drives) and heat emission for a slightly higher latency.
