It can be interesting just to look though /usr/bin, and run man on each one of the files there. That can tell you quite a bit.

Also, if you want to change the display sleep time, it's in System Preferences, under the Display pane. I don't know why you went to the Terminal.

I mentioned the terminal because I think it's an avenue to a better solution for TigerPRO's trouble. He wants to be able to easily walk away from his computer with the screen turned off. Changing the system pref isn't exactly easy. I counted 5 clicks to change the mode. It doesn't appear to be scriptable with Applescript either (although I'm no expert at that, so maybe there is a way...)

However, the command line way of changing the same setting could be put in a shell script, and turned into a 1-click pair of dock icon that toggles the display sleep mode. If one's actually serious about sticking with a repetitive process like this, it needs to be easy... otherwise it's easier just stick with a 5-minute display sleep time like I do.

Yes, the environment can self heal to an extent...however we are creating things that are not found in the environment naturally...how do you address those unnaturally occuring elements? By controlling them some way...either preventing their release, controlling the amount, etc.

As far as the topic goes. I believe the original topic was addressed, and this is simply a subtopic that came up and is being disussed. Obviously people have enough to discuss on the topic by the number of post.

Okay, I thought I'd just put in my 2 cents, from a slightly different perspective...

Yes, the environment is self healing. But what does that mean? I means that we can't kill the planet. We can change the planet, though. We can do enough to the environment that it will adapt to its new form, and suddenly the natural oxygen level in the atmosphere is significantly less than it was, and we can't breath.

I guess my point is that the environment isn't going to try to take care of us. It'll take care of itself. If that means that things will change to become inhospitable for us, then we'll be in trouble. So, yes, the environment can heal itself, but it could condemn us in the process. So, it's in our best interest to avoid changing things so much that the environment's healing process kills us...

VERY POWERFUL AND WELL THOUGHT OUT STATEMENT...THANKS!

Macs tend to be more energy efficient than PCs anyway, because the processors consume for less power than the P4 (even the G5).

The environment is very important to us because we need its well-being to survive. We can survive without Macs. To someone who didn't appear to have heard of global warming or even the holes in the o-zone layer, I can't see how they could be justified in saying things such as "the environment is self-healing."

The environment, under normal conditions, is 'self-healing' in one sense in that there are many cylces that operate within it. Some operate under short timescales (1-10,000 years) while others (such as greenhouse/icehouse) occur with periodicities of millions to tens of millions of years. Unfortunately, there is good evidence that anthropogenic effects (i.e. stuff caused by humans) are upsetting the balance.

I am no heroic and die-hard envionrmentalist, but I do care a great deal about the environment, and how we are continually putting business and profit before the environment. All the western governments need to learn a thing or two here, but I won't get any further or this will get political.

TigerPRO, your screen will not be damaged by having it on a couple of minutes longer but it's nice to see you want to be more energy efficient with it. Less on time means less power used, which means it's better for your iMac (although not noticeably) and better for the environment.
