I use `pianobar` player. But before launching it I need to run `tor` and `polipo`. Both are continuous (are running until interrupted). Basically what I'm looking for is a single command which would spawn `tor` and `polipo` processes (their output is not needed) and then open pianobar in foreground.

edit: turns out `tor` takes several seconds to start, this is why suggested solutions didn't work at first. I post this in case anyone has the same problem:

```
function piano {
    tor &
    polipo &
    sleep 3
    pianobar &&
    killall tor
    killall polipo
}

```
