4. 命令

MacBook-Pro ~ % youtube-dl -h
Usage: youtube-dl [OPTIONS] URL [URL...]

Options:
  General Options:
    -h, --help                           Print this help text and exit
    --version                            Print program version and exit
    -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 given in the global configuration file /etc/youtube-dl.conf: Do not read the user configuration in ~/.config/youtube-dl/config (%APPDATA%/youtube-dl/config.txt on
                                         Windows)
    --config-location PATH               Location of the configuration file; either the path to the config or its containing directory.
    --flat-playlist                      Do not extract the videos of a playlist, only list them.
    --mark-watched                       Mark videos watched (YouTube only)
    --no-mark-watched                    Do not mark videos watched (YouTube only)
    --no-color                           Do not emit color codes in output

  Network Options:
    --proxy URL                          Use the specified HTTP/HTTPS/SOCKS proxy. To enable SOCKS proxy, specify a proper scheme. For example socks5://127.0.0.1:1080/. Pass in an empty string (--proxy "") for direct connection
    --socket-timeout SECONDS             Time to wait before giving up, in seconds
    --source-address IP                  Client-side IP address to bind to
    -4, --force-ipv4                     Make all connections via IPv4
    -6, --force-ipv6                     Make all connections via IPv6

  Geo Restriction:
    --geo-verification-proxy URL         Use this proxy to verify the IP address for some geo-restricted sites. The default proxy specified by --proxy (or none, if the option is not present) is used for the actual downloading.
    --geo-bypass                         Bypass geographic restriction via faking X-Forwarded-For HTTP header
    --no-geo-bypass                      Do not bypass geographic restriction via faking X-Forwarded-For HTTP header
    --geo-bypass-country CODE            Force bypass geographic restriction with explicitly provided two-letter ISO 3166-2 country code
    --geo-bypass-ip-block IP_BLOCK       Force bypass geographic restriction with explicitly provided IP block in CIDR notation

    --max-views COUNT                    Do not download any videos with more than COUNT views
    --match-filter FILTER                Generic video filter. Specify any key (see the "OUTPUT TEMPLATE" for a list of available keys) to match if the key is present, !key to check if the key is not present, key > NUMBER (like "comment_count >
                                         12", also works with >=, <, <=, !=, =) to compare against a number, key = 'LITERAL' (like "uploader = 'Mike Smith'", also works with !=) to match against a string literal and & to require multiple
                                         matches. Values which are not known are excluded unless you put a question mark (?) after the operator. For example, to only match videos that have been liked more than 100 times and disliked less than 50
                                         times (or the dislike functionality is not available at the given service), but who also have a description, use --match-filter "like_count > 100 & dislike_count  .

    --yes-playlist                       Download the playlist, if the URL refers to a video and a playlist.
