multi is an interesting YubNub command. You can use it to run several Google searches simultaneously -- for example, multi gim porsche ferrari lamborghini bmw.
Or the same thing in Yahoo: multi yim porsche ferrari lamborghini bmw.
You can look up 5 dictionary definitions at the same time: multi a blog incumbent electoral insurgent hurricane
Or have lottery numbers automatically chosen for you: multi random 49 49 49 49 49 49
multi is composed of a few other commands. The ifthen and strlength commands were written by Allen Ormond. The % command (for positional parameters) was done by Fuska. And the split command was done by yours truly!
