+**-C, --continue-at <オフセット>**\\
+指定されたオフセットで以前のファイル転送を続行/再開します。指定されたオフセットは、宛先に転送される前にソース ファイルの先頭から数えて、スキップされる正確なバイト数です。アップロードで使用する場合、curl は FTP サーバー コマンド SIZE を使用しません。\\
+「-C -」を使用して、curl に転送を再開する場所/方法を自動的に見つけるように指示します。次に、指定された出力/入力ファイルを使用してそれを把握します。\\
+[[https://curl.se/docs/manpage.html#-C|-C, --continue-at]] が複数回指定された場合、最後に設定された値が使用されます。\\
+例:\\
+  curl -C - https://example.com
