- Description
- -----------
- The **OS** class wraps the most common functionalities for communicating with the host operating system, such as the video driver, delays, environment variables, execution of binaries, command line, etc.
- \ **Note:** In Godot 4, **OS** functions related to window management, clipboard, and TTS were moved to the :ref:`DisplayServer<class_DisplayServer>` singleton (and the :ref:`Window<class_Window>` class). Functions related to time were removed and are only available in the :ref:`Time<class_Time>` class.

- Executes the given process in a *blocking* way. The file specified in ``path`` must exist and be executable. The system path resolution will be used. The ``arguments`` are used in the given order, separated by spaces, and wrapped in quotes.
- If an ``output`` array is provided, the complete shell output of the process is appended to ``output`` as a single :ref:`String<class_String>` element. If ``read_stderr`` is ``true``, the output to the standard error stream is also appended to the array.
- On Windows, if ``open_console`` is ``true`` and the process is a console app, a new terminal window is opened.
- This method returns the exit code of the command, or ``-1`` if the process fails to execute.
- \ **Note:** The main thread will be blocked until the executed command terminates. Use :ref:`Thread<class_Thread>` to create a separate thread that will not block the main thread, or use :ref:`create_process<class_OS_method_create_process>` to create a completely independent process.
- For example, to retrieve a list of the working directory's contents:

- Creates a new process that runs independently of Godot with redirected IO. It will not terminate when Godot terminates. The path specified in ``path`` must exist and be an executable file or macOS ``.app`` bundle. The path is resolved based on the current platform. The ``arguments`` are used in the given order and separated by a space.
- If ``blocking`` is ``false``, created pipes work in non-blocking mode, i.e. read and write operations will return immediately. Use :ref:`FileAccess.get_error<class_FileAccess_method_get_error>` to check if the last read/write operation was successful.
- If the process cannot be created, this method returns an empty :ref:`Dictionary<class_Dictionary>`. Otherwise, this method returns a :ref:`Dictionary<class_Dictionary>` with the following keys:
- - ``"stdio"`` - :ref:`FileAccess<class_FileAccess>` to access the process stdin and stdout pipes (read/write).
- - ``"stderr"`` - :ref:`FileAccess<class_FileAccess>` to access the process stderr pipe (read only).
- - ``"pid"`` - Process ID as an :ref:`int<class_int>`, which you can use to monitor the process (and potentially terminate it with :ref:`kill<class_OS_method_kill>`).

- \ **Note:** Environment variable names are case-sensitive on all platforms except Windows. The ``variable`` name cannot be empty or include the ``=`` character. On Windows, there is a 32767 characters limit for the combined length of ``variable``, ``value``, and the ``=`` and null terminator characters that will be registered in the environment block.

- If ``restart`` is ``true``, restarts the project automatically when it is exited with :ref:`SceneTree.quit<class_SceneTree_method_quit>` or :ref:`Node.NOTIFICATION_WM_CLOSE_REQUEST<class_Node_constant_NOTIFICATION_WM_CLOSE_REQUEST>`. Command-line ``arguments`` can be supplied. To restart the project with the same command line arguments as originally used to run the project, pass :ref:`get_cmdline_args<class_OS_method_get_cmdline_args>` as the value for ``arguments``.
- This method can be used to apply setting changes that require a restart. See also :ref:`is_restart_on_exit_set<class_OS_method_is_restart_on_exit_set>` and :ref:`get_restart_on_exit_arguments<class_OS_method_get_restart_on_exit_arguments>`.
- \ **Note:** This method is only effective on desktop platforms, and only when the project isn't started from the editor. It will have no effect on mobile and Web platforms, or when the project is started from the editor.
- \ **Note:** If the project process crashes or is *killed* by the user (by sending ``SIGKILL`` instead of the usual ``SIGTERM``), the project won't restart automatically.

- |void| **set_use_file_access_save_and_swap**\ (\ enabled\: :ref:`bool<class_bool>`\ ) :ref:`🔗<class_OS_method_set_use_file_access_save_and_swap>`
- If ``enabled`` is ``true``, when opening a file for writing, a temporary file is used in its place. When closed, it is automatically applied to the target file.
- This can useful when files may be opened by other applications, such as antiviruses, text editors, or even the Godot editor itself.

- .. rst-class:: classref-method
- :ref:`Error<enum_@GlobalScope_Error>` **shell_open**\ (\ uri\: :ref:`String<class_String>`\ ) :ref:`🔗<class_OS_method_shell_open>`
- Requests the OS to open a resource identified by ``uri`` with the most appropriate program. For example:
- - ``OS.shell_open("C:\\Users\name\Downloads")`` on Windows opens the file explorer at the user's Downloads folder.
- - ``OS.shell_open("https://godotengine.org")`` opens the default web browser on the official Godot website.
- - ``OS.shell_open("mailto:[email protected]")`` opens the default email client with the "To" field set to ``[email protected]``. See `RFC 2368 - The [code]mailto[/code] URL scheme <https://datatracker.ietf.org/doc/html/rfc2368>`__ for a list of fields that can be added.
- Use :ref:`ProjectSettings.globalize_path<class_ProjectSettings_method_globalize_path>` to convert a ``res://`` or ``user://`` project path into a system path for use with this method.
- \ **Note:** Use :ref:`String.uri_encode<class_String_method_uri_encode>` to encode characters within URLs in a URL-safe, portable way. This is especially required for line breaks. Otherwise, :ref:`shell_open<class_OS_method_shell_open>` may not work correctly in a project exported to the Web platform.
- \ **Note:** This method is implemented on Android, iOS, Web, Linux, macOS and Windows.

- Requests the OS to open the file manager, navigate to the given ``file_or_dir_path`` and select the target file or folder.
- If ``open_folder`` is ``true`` and ``file_or_dir_path`` is a valid directory path, the OS will open the file manager and navigate to the target folder without selecting anything.
- Use :ref:`ProjectSettings.globalize_path<class_ProjectSettings_method_globalize_path>` to convert a ``res://`` or ``user://`` project path into a system path to use with this method.
- \ **Note:** This method is currently only implemented on Windows and macOS. On other platforms, it will fallback to :ref:`shell_open<class_OS_method_shell_open>` with a directory path of ``file_or_dir_path`` prefixed with ``file://``.

- |void| **unset_environment**\ (\ variable\: :ref:`String<class_String>`\ ) |const| :ref:`🔗<class_OS_method_unset_environment>`
- Removes the given environment variable from the current environment, if it exists. The ``variable`` name cannot be empty or include the ``=`` character. The environment variable will be removed for the Godot process and any process executed with :ref:`execute<class_OS_method_execute>` after running :ref:`unset_environment<class_OS_method_unset_environment>`. The removal of the environment variable will *not* persist to processes run after the Godot process was terminated.
