                       installation.
   --infilter={filter} Force an input filter type if possible. For example:
                       --infilter="Calc Office Open XML"

   --nologo            Disables the splash screen at program start.
   --minimized         Starts minimized. The splash screen is not displayed.

                       controlled and opened via the API. Using the parameter,
                       the process can only be ended using the taskmanager
                       (Windows) or the kill command (UNIX-like systems). It
                       cannot be used in conjunction with --quickstart.
   --headless          Starts in "headless mode" which allows using the
                       application without GUI. This special mode can be used
                       when the application is controlled by external clients
                       via the API.
   --norestore         Disables restart and file recovery after a system crash.
   --safe-mode         Starts in a safe mode, i.e. starts temporarily with a
                       fresh user profile and helps to restore a broken
                       configuration.
   --accept={UNO-URL}  Specifies an UNO-URL connect-string to create an UNO
                       acceptor through which other programs can connect to
                       access the API. UNO-URL is string the such kind
                   uno:connection-type,params;protocol-name,params;ObjectName.
   --unaccept={UNO-URL} Closes an acceptor that was created with --accept. Use
                       --unaccept=all to close all open acceptors.
   --language={lang}   Uses specified language, if language is not selected
                       yet for UI. The lang is a tag of the language in IETF
                       language tag.
Developer arguments:
   --terminate_after_init
                       Exit after initialization complete (no documents loaded).
   --eventtesting      Exit after loading documents.
New document creation arguments:
The arguments create an empty document of specified kind. Only one of them may
be used in one command line. If filenames are specified after an argument,
then it tries to open those files in the specified component.
   --writer            Creates an empty Writer document.
   --calc              Creates an empty Calc document.
   --draw              Creates an empty Draw document.
   --impress           Creates an empty Impress document.
   --base              Creates a new database.
   --global            Creates an empty Writer master (global) document.
   --math              Creates an empty Math document (formula).
   --web               Creates an empty HTML document.
File open arguments:
The arguments define how following filenames are treated. New treatment begins
after the argument and ends at the next argument. The default treatment is to
open documents for editing, and create new documents from document templates.
   -n                  Treats following files as templates for creation of new
                       documents.
   -o                  Opens following files for editing, regardless whether
                       they are templates or not.
   --pt {Printername}  Prints following files to the printer {Printername},
                       after which those files are closed. The splash screen
                       does not appear. If used multiple times, only last
                       {Printername} is effective for all documents of all
                       --pt runs. Also, --printer-name argument of
                       --print-to-file switch interferes with {Printername}.
   -p                  Prints following files to the default printer, after
                       which those files are closed. The splash screen does
                       not appear. If the file name contains spaces, then it
                       must be enclosed in quotation marks.
   --view              Opens following files in viewer mode (read-only).
   --show              Opens and starts the following presentation documents
                       of each immediately. Files are closed after the showing.
                       Files other than Impress documents are opened in
                       default mode , regardless of previous mode.
   --convert-to OutputFileExtension[:OutputFilterName]
     [--outdir output_dir] [--convert-images-to]
                       Batch convert files (implies --headless). If --outdir
                       isn't specified, then current working directory is used
                       as output_dir. If --convert-images-to is given, its
                       parameter is taken as the target MIME format for *all*
                       images written to the output format. If --convert-to is
                       used more than once, the last value of OutputFileExtension
                       [:OutputFilterName] is effective. If --outdir is used more
                       than once, only its last value is effective. For example:
                   --convert-to pdf *.odt
                   --convert-to epub *.doc
                   --convert-to pdf:writer_pdf_Export --outdir /home/user *.doc
                   --convert-to "html:XHTML Writer File:UTF8" *.doc
                   --convert-to "txt:Text (encoded):UTF8" *.doc
   --print-to-file [--printer-name printer_name] [--outdir output_dir]
                       Batch print files to file. If --outdir is not specified,
                       then current working directory is used as output_dir.
                       If --printer-name or --outdir used multiple times, only
                       last value of each is effective. Also, {Printername} of
                       --pt switch interferes with --printer-name.
   --cat               Dump text content of the following files to console
                       (implies --headless). Cannot be used with --convert-to.
   --script-cat        Dump text content of any scripts embedded in the files to console
                       (implies --headless). Cannot be used with --convert-to.
   -env:<VAR>[=<VALUE>] Set a bootstrap variable. For example: to set
                       a non-default user profile path:
                       -env:UserInstallation=file:///tmp/test
Ignored switches:
   -psn                Ignored (MacOS X only).
   -Embedding          Ignored (COM+ related; Windows only).
   --nofirststartwizard Does nothing, accepted only for backward compatibility.
   --protector {arg1} {arg2}
                       Used only in unit tests and should have two arguments.
