The -o parameter in aria2c can't rename the downloaded file

Question

aria2c -S  /home/se.torrent

Files:    
idx|path/length    
===+===========================================================================
1|./test.mkv        
 |283MiB (297,429,086)        

---+---------------------------------------------------------------------------

I want to save the downloaded file as ok.mkv in /tmp.

aria2c -d   /tmp  -o  ok.mkv    /home/se.torrent

The downloaded name can't be changed into /tmp/ok.mkv ,it is still
/tmp/test.mkv when the command executed.

In manual of aria2c -h ,there is no strings such as:
NOTE: You cannot specify a file name for Metalink or BitTorrent downloads.

Solution

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:

The string is contained in the man pages as I have detailed below, which are accessed by running the command man aria2c. Hope that clears it up for you :)

In manual of aria2c -h ,there is no strings such as NOTE: You cannot specify a file name for Metalink or BitTorrent downloads. did you add it?

@it_is_a_literature Did I add it in a quest for reputation points? No :). You have not looked at the man pages which are accessed from the Terminal by typing in: man aria2c, the information is there... If you read to the bottom of the text given in aria2c -h you will see a pointer to this that reads: Refer to man page for more information.
