rename file

https://askubuntu.com/questions/790633/the-o-parameter-in-aria2c-cant-rename-the-downloaded-file

You are out of luck when attempting to rename .torrent files with aria2c, from the man pages:

 -o, --out=<FILE>
      The   file name of the downloaded file. When the
      --force-sequential option is used, this option is ignored.

      NOTE:
      You  cannot  specify  a  file name for Metalink or BitTorrent
      downloads.

Note that this information is not contained in the help given with the command:

aria2c -h

but in the man pages that are read with the following:

man aria2c

With other types of files aria2c works very nicely and appropriately renames as directed:
