### class LinuxDistribution
     |  LinuxDistribution(include_lsb: Optional[bool] = None, os_release_file: str = '', distro_release_file: str = '', include_uname: Optional[bool] = None, root_dir: Optional[str] = None, include_oslevel: Optional[bool] = None) -> None
     |
     |  Provides information about a OS distribution.
     |
     |  This package creates a private module-global instance of this class with
     |  default initialization arguments, that is used by the
     |  `consolidated accessor functions`_ and `single source accessor functions`_.
     |  By using default initialization arguments, that module-global instance
     |  returns data about the current OS distribution (i.e. the distro this
     |  package runs on).
     |
     |  Normally, it is not necessary to create additional instances of this class.
     |  However, in situations where control is needed over the exact data sources
     |  that are used, instances of this class can be created with a specific
     |  distro release file, or a specific os-release file, or without invoking the
     |  lsb_release command.
     |
     |  Methods defined here:
     |
     |  __init__(self, include_lsb: Optional[bool] = None, os_release_file: str = '', distro_release_file: str = '', include_uname: Optional[bool] = None, root_dir: Optional[str] = None, include_oslevel: Optional[bool] = None) -> None
     |      The initialization method of this class gathers information from the
     |      available data sources, and stores that in private instance attributes.
     |      Subsequent access to the information items uses these private instance
     |      attributes, so that the data sources are read only once.
     |
     |      Parameters:
     |
     |      * ``include_lsb`` (bool): Controls whether the
     |        `lsb_release command output`_ is included as a data source.
     |
     |        If the lsb_release command is not available in the program execution
     |        path, the data source for the lsb_release command will be empty.
     |
     |      * ``os_release_file`` (string): The path name of the
     |        `os-release file`_ that is to be used as a data source.
     |
     |        An empty string (the default) will cause the default path name to
     |        be used (see `os-release file`_ for details).
     |
     |        If the specified or defaulted os-release file does not exist, the
     |        data source for the os-release file will be empty.
     |
     |      * ``distro_release_file`` (string): The path name of the
     |        `distro release file`_ that is to be used as a data source.
     |
     |        An empty string (the default) will cause a default search algorithm
     |        to be used (see `distro release file`_ for details).
     |
     |        If the specified distro release file does not exist, or if no default
     |        distro release file can be found, the data source for the distro
     |        release file will be empty.
     |
     |      * ``include_uname`` (bool): Controls whether uname command output is
     |        included as a data source. If the uname command is not available in
     |        the program execution path the data source for the uname command will
     |        be empty.
     |
     |      * ``root_dir`` (string): The absolute path to the root directory to use
     |        to find distro-related information files. Note that ``include_*``
     |        parameters must not be enabled in combination with ``root_dir``.
     |
     |      * ``include_oslevel`` (bool): Controls whether (AIX) oslevel command
     |        output is included as a data source. If the oslevel command is not
     |        available in the program execution path the data source will be
     |        empty.
     |
     |      Public instance attributes:
     |
     |      * ``os_release_file`` (string): The path name of the
     |        `os-release file`_ that is actually used as a data source. The
     |        empty string if no distro release file is used as a data source.
     |
     |      * ``distro_release_file`` (string): The path name of the
     |        `distro release file`_ that is actually used as a data source. The
     |        empty string if no distro release file is used as a data source.
     |
     |      * ``include_lsb`` (bool): The result of the ``include_lsb`` parameter.
     |        This controls whether the lsb information will be loaded.
     |
     |      * ``include_uname`` (bool): The result of the ``include_uname``
     |        parameter. This controls whether the uname information will
     |        be loaded.
     |
     |      * ``include_oslevel`` (bool): The result of the ``include_oslevel``
     |        parameter. This controls whether (AIX) oslevel information will be
     |        loaded.
     |
     |      * ``root_dir`` (string): The result of the ``root_dir`` parameter.
     |        The absolute path to the root directory to use to find distro-related
     |        information files.
     |
     |      Raises:
     |
     |      * :py:exc:`ValueError`: Initialization parameters combination is not
     |         supported.
     |
     |      * :py:exc:`OSError`: Some I/O issue with an os-release file or distro
     |        release file.

## FUNCTIONS
### build_number
        Return the build number of the current OS distribution, as a string,
        if provided.
        Otherwise, the empty string is returned. The build number is the third part
        of the dot-separated version string.

        For a description of the *best* parameter, see the :func:`distro.version`
        method.

### codename
        Return the codename for the release of the current OS distribution,
        as a string.

        If the distribution does not have a codename, an empty string is returned.

        Note that the returned codename is not always really a codename. For
        example, openSUSE returns "x86_64". This function does not handle such
        cases in any special way and just returns the string it finds, if any.

### Lookup hierarchy:

        * the codename within the "VERSION" attribute of the os-release file, if
          provided,

        * the value of the "Codename" attribute returned by the lsb_release
          command,

        * the value of the "<codename>" field of the distro release file.

### distro_release_attr
        Return a single named information item from the distro release file
        data source of the current OS distribution.

        Parameters:

        * ``attribute`` (string): Key of the information item.

        Returns:

        * (string): Value of the information item, if the item exists.
          The empty string, if the item does not exist.

        See `distro release file`_ for details about these information items.

### distro_release_info
        Return a dictionary containing key-value pairs for the information items
        from the distro release file data source of the current OS distribution.

        See `distro release file`_ for details about these information items.

### id
        Return the distro ID of the current distribution, as a
        machine-readable string.

        For a number of OS distributions, the returned distro ID value is
        *reliable*, in the sense that it is documented and that it does not change
        across releases of the distribution.

        This package maintains the following reliable distro ID values:

        ==============  =========================================
        Distro ID       Distribution
        ==============  =========================================
        "ubuntu"        Ubuntu
        "debian"        Debian

        "linuxmint"     Linux Mint
        "mageia"        Mageia
        "mandriva"      Mandriva Linux
        "parallels"     Parallels
        "pidora"        Pidora
        "raspbian"      Raspbian
        "oracle"        Oracle Linux (and Oracle Enterprise Linux)
        "scientific"    Scientific Linux
        "slackware"     Slackware
        "xenserver"     XenServer
        "openbsd"       OpenBSD
        "netbsd"        NetBSD

        "midnightbsd"   MidnightBSD
        "rocky"         Rocky Linux
        "aix"           AIX
        ==============  =========================================

        If you have a need to get distros for reliable IDs added into this set,
        or if you find that the :func:`distro.id` function returns a different
        distro ID for one of the listed distros, please create an issue in the
        `distro issue tracker`_.

### Lookup hierarchy and transformations:

        First, the ID is obtained from the following sources, in the specified
        order. The first available and non-empty value is used:

        * the value of the "ID" attribute of the os-release file,

        * the value of the "Distributor ID" attribute returned by the lsb_release
          command,

        * the first part of the file name of the distro release file,

        The so determined ID value then passes the following transformations,
        before it is returned by this method:

        * it is translated to lower case,

        * blanks (which should not be there anyway) are translated to underscores,

        * a normalization of the ID is performed, based upon
          `normalization tables`_. The purpose of this normalization is to ensure
          that the ID is as reliable as possible, even across incompatible changes
          in the OS distributions. A common reason for an incompatible change is
          the addition of an os-release file, or the addition of the lsb_release
          command, with ID values that differ from what was previously determined
          from the distro release file name.

### info
        Return certain machine-readable information items about the current OS
        distribution in a dictionary, as shown in the following example:

        .. sourcecode:: python

            {
                'id': 'rhel',
                'version': '7.0',
                'version_parts': {
                    'major': '7',
                    'minor': '0',
                    'build_number': ''
                },
                'like': 'fedora',
                'codename': 'Maipo'
            }

        The dictionary structure and keys are always the same, regardless of which
        information items are available in the underlying data sources. The values
        for the various keys are as follows:

        * ``id``:  The result of :func:`distro.id`.

        * ``version``:  The result of :func:`distro.version`.

        * ``version_parts -> major``:  The result of :func:`distro.major_version`.

        * ``version_parts -> minor``:  The result of :func:`distro.minor_version`.

        * ``version_parts -> build_number``:  The result of
          :func:`distro.build_number`.

        * ``like``:  The result of :func:`distro.like`.

        * ``codename``:  The result of :func:`distro.codename`.

        For a description of the *pretty* and *best* parameters, see the
        :func:`distro.version` method.

### like
        Return a space-separated list of distro IDs of distributions that are
        closely related to the current OS distribution in regards to packaging
        and programming interfaces, for example distributions the current
        distribution is a derivative from.

### Lookup hierarchy:

        This information item is only provided by the os-release file.
        For details, see the description of the "ID_LIKE" attribute in the
        `os-release man page
        <<http://www.freedesktop.org/software/systemd/man/os-release.html>>`_.

### linux_distribution
        .. deprecated:: 1.6.0

            :func:`distro.linux_distribution()` is deprecated. It should only be
            used as a compatibility shim with Python's
            :py:func:`platform.linux_distribution()`. Please use :func:`distro.id`,
            :func:`distro.version` and :func:`distro.name` instead.

        Return information about the current OS distribution as a tuple
        ``(id_name, version, codename)`` with items as follows:

        * ``id_name``:  If *full_distribution_name* is false, the result of
          :func:`distro.id`. Otherwise, the result of :func:`distro.name`.

        * ``version``:  The result of :func:`distro.version`.

        * ``codename``:  The extra item (usually in parentheses) after the
          os-release version number, or the result of :func:`distro.codename`.

        The interface of this function is compatible with the original
        :py:func:`platform.linux_distribution` function, supporting a subset of
        its parameters.

        The data it returns may not exactly be the same, because it uses more data
        sources than the original function, and that may lead to different data if
        the OS distribution is not consistent across multiple data sources it
        provides (there are indeed such distributions ...).

        Another reason for differences is the fact that the :func:`distro.id`
        method normalizes the distro ID string to a reliable machine-readable value
        for a number of popular OS distributions.

### lsb_release_attr
        Return a single named information item from the lsb_release command output
        data source of the current OS distribution.

        Parameters:

        * ``attribute`` (string): Key of the information item.

        Returns:

        * (string): Value of the information item, if the item exists.
          The empty string, if the item does not exist.

        See `lsb_release command output`_ for details about these information
        items.

### lsb_release_info
        Return a dictionary containing key-value pairs for the information items
        from the lsb_release command data source of the current OS distribution.

        See `lsb_release command output`_ for details about these information
        items.

### major_version
        Return the major version of the current OS distribution, as a string,
        if provided.
        Otherwise, the empty string is returned. The major version is the first
        part of the dot-separated version string.

        For a description of the *best* parameter, see the :func:`distro.version`
        method.

### minor_version
        Return the minor version of the current OS distribution, as a string,
        if provided.
        Otherwise, the empty string is returned. The minor version is the second
        part of the dot-separated version string.

        For a description of the *best* parameter, see the :func:`distro.version`
        method.

### name
        Return the name of the current OS distribution, as a human-readable
        string.

        If *pretty* is false, the name is returned without version or codename.
        (e.g. "CentOS Linux")

        If *pretty* is true, the version and codename are appended.
        (e.g. "CentOS Linux 7.1.1503 (Core)")

        The name is obtained from the following sources, in the specified order.
        The first available and non-empty value is used:

        * If *pretty* is false:

          - the value of the "NAME" attribute of the os-release file,

          - the value of the "Distributor ID" attribute returned by the lsb_release
            command,

          - the value of the "<name>" field of the distro release file.

        * If *pretty* is true:

          - the value of the "PRETTY_NAME" attribute of the os-release file,

          - the value of the "Description" attribute returned by the lsb_release
            command,

          - the value of the "<name>" field of the distro release file, appended
            with the value of the pretty version ("<version_id>" and "<codename>"
            fields) of the distro release file, if available.

### os_release_attr
        Return a single named information item from the os-release file data source
        of the current OS distribution.

        Parameters:

        * ``attribute`` (string): Key of the information item.

        Returns:

        * (string): Value of the information item, if the item exists.
          The empty string, if the item does not exist.

        See `os-release file`_ for details about these information items.

### os_release_info
        Return a dictionary containing key-value pairs for the information items
        from the os-release file data source of the current OS distribution.

        See `os-release file`_ for details about these information items.

### uname_attr
        Return a single named information item from the distro release file
        data source of the current OS distribution.

        Parameters:

        * ``attribute`` (string): Key of the information item.

        Returns:

        * (string): Value of the information item, if the item exists.
                    The empty string, if the item does not exist.

### uname_info
        Return a dictionary containing key-value pairs for the information items
        from the distro release file data source of the current OS distribution.

### version
        Return the version of the current OS distribution, as a human-readable
        string.

        If *pretty* is false, the version is returned without codename (e.g.
        "7.0").

        If *pretty* is true, the codename in parenthesis is appended, if the
        codename is non-empty (e.g. "7.0 (Maipo)").

        Some distributions provide version numbers with different precisions in
        the different sources of distribution information. Examining the different
        sources in a fixed priority order does not always yield the most precise
        version (e.g. for Debian 8.2, or CentOS 7.1).

        Some other distributions may not provide this kind of information. In these
        cases, an empty string would be returned. This behavior can be observed
        with rolling releases distributions (e.g. Arch Linux).

        The *best* parameter can be used to control the approach for the returned
        version:

        If *best* is false, the first non-empty version number in priority order of
        the examined sources is returned.

        If *best* is true, the most precise version number out of all examined
        sources is returned.

### Lookup hierarchy:

        In all cases, the version number is obtained from the following sources.
        If *best* is false, this order represents the priority order:

        * the value of the "VERSION_ID" attribute of the os-release file,
        * the value of the "Release" attribute returned by the lsb_release
          command,
        * the version number parsed from the "<version_id>" field of the first line
          of the distro release file,
        * the version number parsed from the "PRETTY_NAME" attribute of the
          os-release file, if it follows the format of the distro release files.
        * the version number parsed from the "Description" attribute returned by
          the lsb_release command, if it follows the format of the distro release
          files.

### version_parts
        Return the version of the current OS distribution as a tuple
        ``(major, minor, build_number)`` with items as follows:

        * ``major``:  The result of :func:`distro.major_version`.

        * ``minor``:  The result of :func:`distro.minor_version`.

        * ``build_number``:  The result of :func:`distro.build_number`.

        For a description of the *best* parameter, see the :func:`distro.version`
        method.
