was bedeutet der alleinstehende Bindestrich (-) von Curl?

wofür steht der alleinstehende Bindestrich (zwischen dem -C& -O) in diesem Befehl?

curl -C - -O http://www.intersil.com/content/dam/Intersil/documents/fn67/fn6742.pdf

FWIW - Ich folge einem TutorialHier.

Antwort1

-C -bestimmt automatisch, wie die Übertragung fortgesetzt wird, basierend auf den Eingabe- und Ausgabedateien.

Ausman curl(beachten Sie den zweiten Absatz):

   -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.
