Hummm.  Good point.  (Likewise the yes command.)  However, I think it 
requires a bit more thought.  My knee-jerk reaction to this is that 
anyone who is technically aware enough to know how to use something like 
this without getting bitten will already know about -y, or at least 
figure it out.

IIRC APT only prompts if:
* Packages other than those explicitly specified on the command line 
will be installed, e.g. to satisfy dependencies
* Un-authenticated packages will be installed
* Packages will be removed, due to a conflict or newer package 
superseding an older one somehow

I forget if yum is "smart" like that, or if it always asks blindly.

Obviously, the point of asking for user confirmation is that what was 
given on the command line is not always what will actually be done. 
Personally, I think it's a *really bad idea* to -y something like this, 
e.g., in cron, and I don't do it.  Those who are determined to shoot 
themselves in the foot can always find a way, I don't need to hand out 
bullets.  :-)

Having said all that, thank you for the feedback, I do appreciate it, 
even if that isn't apparent.  :-)

Thanks,
JP

Microsoft has single-handedly nullified Moore's Law.
Innate design flaws of Windows make a personal firewall, anti-virus
and anti-malware software mandatory. The resulting software arms race
has effectively flattened Moore's Law on hardware running Windows.
