Earlier quoted context omitted.
FYI, transmission-cli is considered deprecated by the Transmission developers. Using both transmission-daemon and transmission-remote is the recommended approach. Actually, transmission-cli uses transmission-daemon internally and they share the same configuration. transmission-cli is still useful for one-off downloads, but I still prefer the recommended way because I'd like to seed older torrents some more time.
> transmission-cli is considered deprecated Wah! Bad news! I like to kick off a download from an SSH shell. Now I have to find out what transmission+remote is.
$ transmission-remote -a one.torrent two.torrent
