Where is the example using grep as the OP asked? Oh, wait...

Again Tad, you DON'T HAVE TO POST. Control that smartass urge of yours,
thanks. It will make this group way more friendly.

Likewise, NOBODY REQUIRES YOU TO READ EVERY POST.

I'd rather the group be expert-friendly than lazy-newbie-friendly,
myself.

Well, the problem is, one has to open a post to see what is in it. And
since Tad does now and then post something interesting, I still consider
it worth to open his posts. In short, while true, your statement is
somewhat pointless.

I prefer something in the middle [1]. Also, try to keep in mind that a
lazy-newbie question can result in an interesting discussion that people
who are not lazy and who want to learn might cherish. I am sure you are
able to recall several examples of this.

Personally I wouldn't mind if everybody stopped replying to lazy-newbies
and have the FAQ bot post daily a message:

If you wonder why you don't get a reply...

with the usual pointers.

I am sure that it would improve the readability and the friendliness of
this group. And as since this sounds reasonable (at least to me) it will
never see the light of day.

[1] I hate it when regulars can get away with stuff they wouldn't let
any newbie get away with.

that is why they are called regulars. they have (usually) earned some
reputation points or have external (like cpan and other perl community)
experience worth listening too. teaching a newbie to use the FAQ is a
good thing. how that is done may be your issue but i like tad's way as
it hits hard and that is usually needed for newbies to get off the track
of asking FAQs. perl's faq collection is massive and written and edited
(here) very well. it is the best way to leverage the learning curve. i
always recommend to newbies to scan/skim the entire faq as soon as they
can. then read it in more depth as needed.

OK, my bad: at every single newbie that should have done a bit more
research in the eyes of the regulars.

I agree, no question about that. I only think that in a group with
dwindling traffic it becomes annoying if quite some post just reiterate
what has been posted daily for the past years. I thought that
programming was also about seeing a problem and providing an automated
solution to it.

> Right, but it is easier to ignore when delivered nicely.

Again, you don't have to reply. If your advice is ignored, score the
poster low, and igonre his/her future posts.

> Ignoring accepted netiquette is certainly bad for our newsgroup.

So is behavior that most (I hope) wouldn't show when in public, actually
facing the newbie.

> I don't want bad for this newsgroup.

Me neither, hence my attempt to look for a solution that will reduce the
constant stream of correcting newbies. It rarely works.

So why don't you reply to his posts trying to correct him with harsh
language? OTOH, maybe my friendly request has worked. It doesn't matter
which happens since either will prove a point I made :-).

I talk in general: too many posts IMO in this newsgroup are bashing
newbies. If you were just bashing we wouldn't have this discussion to
begin with.

Aren't too many posts here just bashing? IMO it is. You can disagree
with that, but it has nothing to do with my credibility. Maybe we have a
different definition of bashing.

Help that comes with a kick in the balls is just a kick in the balls IMO.

OK, well, in that case this group isn't just for me.

Did I write that? I have no problem to provide the code. I have also no
problem to run a bot daily *but* I think it's easier to have the current
FAQ bot post one additional message. On top of that I am not going to
run a bot without approval of the majority of regulars here.

I doubt it, since it only works if everybody in this group ignores each
question that doesn't use this group as the last resort and/or doesn't
follow the posting guidelines.

I thought you gave classes at Stonehenge but just read that you only
sell them. Figures.
