-U, --update                         Update this program to latest version.
                                     Make sure that you have sufficient
                                     permissions (run with sudo if needed)
-i, --ignore-errors                  Continue on download errors, for
                                     example to skip unavailable videos in a
                                     playlist
--abort-on-error                     Abort downloading of further videos (in
                                     the playlist or the command line) if an
                                     error occurs
--dump-user-agent                    Display the current browser
                                     identification
--list-extractors                    List all supported extractors
--extractor-descriptions             Output descriptions of all supported
                                     extractors
--force-generic-extractor            Force extraction to use the generic
                                     extractor
--default-search PREFIX              Use this prefix for unqualified URLs.
                                     For example "gvsearch2:" downloads two
                                     videos from google videos for youtube-
                                     dl "large apple". Use the value "auto"
                                     to let youtube-dl guess ("auto_warning"
                                     to emit a warning when guessing).
                                     "error" just throws an error. The
                                     default value "fixup_error" repairs
                                     broken URLs, but emits an error if this
                                     is not possible instead of searching.
--ignore-config                      Do not read configuration files. When

                                     (%APPDATA%/youtube-dl/config.txt on
                                     Windows)
--config-location PATH               Location of the configuration file;
                                     either the path to the config or its

--flat-playlist                      Do not extract the videos of a
                                     playlist, only list them.
