I've used this before and it works well, but I can only kind-of recommend it. If you are doing a presentation at some large conference where people will not be interrupting you with questions as you do your presentation, then I would recommend it. HOWEVER most of us do presentations to smaller more informal groups: coworkers, local coding meetups, etc. In those situations people are more likely to interrupt you and ask you something that would normally be doable IF you weren't running a script So, IF you're going to use this in an interruptable situation I would strongly recommend mentioning BEFORE you start, that you are executing the commands live, but that you're using an interactive script to do it so that you don't screw anything up. Otherwise you look like a fraud when someones like "what about X" and you're all ... "well yes, but i can't do that right now because while it looks like I've been typing these commands, in reality I've been deceiving you and can't break out of this script or everything goes awry... but yes i could do that.... if i wasn't pretending i was actually typing this stuff." And yes, I'm speaking from experience, although i used different words. It's really awkward. Don't do it.
