IMHO, this should have been called -t (but that's taken) for "pass TTY to child process" - it's a very specific sort of work-around one needs to do for some things. Talking about /dev/tty opens it up too much for bikeshedding, unfortunately. There is one related general option I am interested in, and which I will try to add to FreeBSD at some time in the near future, and that is the option to read the *input* from a file, leaving things unobstructed. I use xargs for mp3 playing a lot, so that's where both things come in use for me.
