FWIW-私はチュートリアルに従っていますここ。

答え1

-C -入力ファイルと出力ファイルに基づいて、転送を再開する方法を自動的に決定します。

からman curl（2番目の段落に注目してください）

   -C/--continue-at <offset>
          Continue/Resume a previous file transfer at the  given  offset.
          The  given  offset  is  the  exact number of bytes that will be
          skipped, counting from the beginning of the source file  before
          it  is  transferred  to the destination.  If used with uploads,
          the FTP server command SIZE will not be used by curl.

          Use "-C -" to tell curl to automatically find out where/how  to
          resume  the transfer. It then uses the given output/input files
          to figure that out.

          If this option is used several times,  the  last  one  will  be
          used.
