"That is, as I've always understood, one of the main reasons to script things out in the first place. The other reasons, like automation, efficiency, etc, are pretty much ignored here, even though we will be automating a repetitive action and that, by definition, will make our waste of company time more efficient. No matter how you look at them, automation and efficiency always seem to be a good thing ;)

"This "script" is really just a simple pipe-slam so that we can figure out who's on the machine with us (my preference is for a script, but - as you'll soon see - this could just as easily be an alias, etc). Sure, we could just type "w" or "who," (and "w" does form the base of this bash one-liner script), but we'd like to have this whole thing look more personal. And by personal, I mean, we'd like to know who else is on other than us by UID or login name. The functionality (or relative merit) of this script depends heavily on the way in which users were created on your machine in the first place. If no "comment" (or "gecos") field is populated for users on your system, this command-chain is completely worthless."
