  <refsect1><title>DESCRIPTION</title>
    <para>
      <command>udisksctl</command> is a command-line program used
      to interact with the
      <citerefentry><refentrytitle>udisksd</refentrytitle><manvolnum>8</manvolnum></citerefentry>
      daemon process.

          <para>
            Shows detailed information about

      <varlistentry>
        <term><option>mount</option></term>
        <listitem>
          <para>
            Mounts a device. The device will be mounted in a
            subdirectory in the <filename>/media</filename> hierarchy
            - upon successful completion, the mount point will be
            printed to standard output.
          </para>
          <para>
            The device will be mounted with a safe set of default
            options. You can influence the options passed to the
            <citerefentry><refentrytitle>mount</refentrytitle><manvolnum>8</manvolnum></citerefentry>
            command with <option>--options</option>. Note that only
            safe options are allowed - requests with inherently unsafe
            options such as <parameter>suid</parameter> or
            <parameter>dev</parameter> that would allow the caller to
            gain additional privileges, are rejected.
          </para>

      <varlistentry>
        <term><option>unmount</option></term>
        <listitem>
          <para>
            Unmounts a device. This only works if the device is
            mounted. The option <option>--force</option> can be used
            to request that the device is unmounted even if active
            references exists.

            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.

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

          <para>
            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.
          </para>
          <para>
            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.

    <title>COMMON OPTIONS</title>
    <para>
      The option <option >--no-user-interaction</option> can be used
      to request that no interaction (such as the user being
      presented with an authentication dialog) must occur when
      checking with
      <citerefentry><refentrytitle>polkit</refentrytitle><manvolnum>8</manvolnum></citerefentry>
      whether the caller is authorized to perform the requested
      action.
    </para>
  </refsect1>

  <refsect1><title>AUDIENCE</title>
    <para>
      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
      <citerefentry><refentrytitle>polkit</refentrytitle><manvolnum>8</manvolnum></citerefentry>.
      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
      <quote>API STABILITY</quote> section of
      <link linkend="udisks.8"><citerefentry><refentrytitle>udisks</refentrytitle><manvolnum>8</manvolnum></citerefentry></link>
      for more information.
    </para>
  </refsect1>

  <refsect1><title>BASH COMPLETION</title>
    <para>
      <command>udisksctl</command> ships with a bash completion script to
      complete commands, objects, block devices and some options.
