How to display the status of the torrent from the terminal

Today I need to see the status of torrents from the terminal on the raspberry. After obtaining this information, you can implement a lot of things (turn on an LED when a torrent is finished, send an email, write something on the lcd monitor etc ...).
The solution is the following:

transmission-remote --auth=username:password -l

but if, as in my case the transmission is non-standard port or host is different just use the command

transmission-remote host:port --auth=username:password -l

After obtaining the status of the torrent you can do the "parsing" of the result to be able to implement in a script (send mail, php page, lcd, led etc ...)

For more information and options read the man transmission-remote
