[ That "Last-modified:" date above refers to this document, not to the
Perl FAQ itself! The last major update of the Perl FAQ was in Summer of
1998; of course, ongoing updates are made as needed. ]
For most people, this URL should be all you need in order to find Perl's
Frequently Asked Questions (and answers).
http://cpan.perl.org/doc/FAQs/
Please look over (but never overlook!) the FAQ and related docs before
posting anything to the comp.lang.perl.* family of newsgroups.
# # # # # # # # # # # # # # # # # # # # # # # # # # # # # #
Beginning with Perl version 5.004, the Perl distribution itself includes
the Perl FAQ. If everything is pro-Perl-y installed on your system, the
FAQ will be stored alongside the rest of Perl's documentation, and one
of these commands (or your local equivalents) should let you read the FAQ.
perldoc perlfaq
man perlfaq
If a recent version of Perl is not properly installed on your system,
you should ask your system administrator or local expert to help. If you
find that a recent Perl distribution is lacking the FAQ or other important
documentation, be sure to complain to that distribution's author.
If you have a web connection, the first and foremost source for all things
Perl, including the FAQ, is the Comprehensive Perl Archive Network (CPAN).
CPAN also includes the Perl source code, pre-compiled binaries for many
platforms, and a large collection of freely usable modules, among its
560_986_526 bytes (give or take a little) of super-cool (give or take
a little) Perl resources.
http://cpan.perl.org/
http://www.perl.com/CPAN/
http://cpan.perl.org/doc/FAQs/FAQ/html/perlfaq.html
http://www.perl.com/CPAN/doc/FAQs/FAQ/html/perlfaq.html
You may wish or need to access CPAN via anonymous FTP. (Within CPAN,
you will find the FAQ in the /doc/FAQs/FAQ directory. If none of these
selected FTP sites is especially good for you, a full list of CPAN sites
is in the SITES file within CPAN.)

Switzerland ftp://sunsite.cnlab-switch.ch/mirror/CPAN/
Chile ftp://ftp.ing.puc.cl/pub/unix/perl/CPAN/
If you have no connection to the Internet at all (so sad!) you may wish
to purchase one of the commercial Perl distributions on CD-Rom or other
media. Your local bookstore should be able to help you to find one.
Another possibility is to use one of the FTP-via-email services; for

I guess I'd start out by writing a Perl program and then ask the
newsgroup for help if I ran into any problems that aren't answered in
the FAQ's or documentation.

Do I catch you well that your script can be rewritten as
$ perl -w
use strict;
my %checksums = ( "a" => [ 5, 7 ] );
my @status;
$status[9] = 7;
if( exists( $checksums{"a"} ) && $checksums{"a"}->[1] == $status[9] )
{ print $status[7], "Q\n"; }
__END__
Use of uninitialized value at - line 5.
Q
?
The problem might be that the uninitialized value is in the block you
run after that if. What's in there?

Yes. In general, you need to use a debugger (such as gdb) to look at core
files. Having said that, your perl script shouldn't coredump, so perhaps you
should run your script through the perl debugger ("perl -d") and find out
what's really going wrong.

Message-Id: <slrn6u5c7g.2bm.dsnyder@david.snyder.lan>
Hello Murali,
One thing that I have done in situations like this is to schedule
the job using at(1) instead of forking the CGI script. For example:
system( "at", "now", "my_script", "arguments" );
It's not as cool as re-opening the child processes STDOUT and STDERR
to a file, but it's easy to do as long as the userid under which your
web server is running is able to use at(1). Check
/var/adm/cron/at.allow or /etc/at.allow or the man page for your at(1)
command.

You could use a setld-kit for Perl on DIGITAL UNIX (currently 5.004_4)
as well.
You find it on
ftp://ftp.digital.com/pub/Digital/PERL5004SETLD.tar
ftp://ftp.digital.com/pub/Digital/PERL5004SETLD.readme
or

You need to 'use Exporter;' because all classes need to have
Exporter as a superclass. Of course, you could instead 'use Some::Module;'
which itself has Exporter as a superclass, etc. etc.
On the other hand, not only do you _not_ have to export methods defined in
a class (via the @EXPORT or @EXPORT_OK variables), you definitely should *NOT*
do such exporting. By implementing your modules as classes, you avoid the
necessity of cluttering the namespaces of other modules.

Soooo,
Yes you can. The easiest way is to have the Access "database" on an NT
server and use the ODBC drivers at http://www.roth.net/odbc to connect
to them. If you are on an UNIX server, I have heard that there are some
commercially ($$$) available products that allow you to connect to
Access.
There have been some recent messages about this so if you do a search on
DejaNews I am sure you can find more information about the UNIX
products.
Good luck,
Brent

For general information:
Firstly Karma isn't measured by points
Secondly just giving sets up the return for karma at a very basic level.
Your every action, thought and word throught your every existence creates
enormous ripples on your karma and if you're basic motivations are other than
that of being the best person you can, you will find yourself on the receiving
end of the bad karma that you yourself have generated until you no longer
generate it. This is what is meant by the "Transmigration of the souls".
Things which undo the creation of good karma are:
complacency
intollerance
not respecting the sacred nature of life
narrow mindedness
stubborness
insicerity
Of which insincerity is a pretty major one.

Try about 10-20 each day, and that's _after_ the spam filters and killfiles
etc ad infinitum. And there is a definite correlation to how many posts I
have been making on Usenet, and to which groups - some groups are just
killers, and its normally the ones you would least expect - alt.atheism for
example seems to have a veritable horde of spammers trawling it for
addresses. Go figure.
Anyway, IME it seems that posting a URL is more damaging than posting an
email address - when I post my email address to a group, I get spam at that
email address - however, when I post my URL I get spam at every single one
of my email addresses that is listed on the URL or pages linked to by the
URL - I guess the usenet spambots just forward info to the web spambots
(bleeuch) - this is easily demonstrable for me at least because I can make
up addresses on-the-fly such as spam-address-1@fearsome.net etc for testing.
If someone wishes to post anonymously to avoid this, let them. Spam is a
huge pain in the ass not least because it is invariably underhand - never a
return address and rarely (probably because I'm not very good at it) a
traceable origin.
I can't see (in particular Tom C's) people's problem with people munging
their address in usenet posts - how the hell does it affect you - if you
want to reply to them, do so in the same medium as their original message,
following convention, and post a usenet response. You all champion spam
filters, but I find them to be of very limited use - unless you have the
email address of every single spammer in a database, every filtering effort
will fall short, because it is _impossible_ to differentiate between a real
message and a carefully-disguised spam.

I post ungodly quantities of articles to Usenet, have done so for five
years from multiple addresses, and nearly all of those addresses are still
valid and still reach me. So this tells me that either it's the (somewhat
limited) IP address blocking that we do or it's just the fact that I'm at
a .edu site that's making the difference. Although I also post quite
regularly from a .org address.

My home page URL has been in my signature for at least three years, and it
has multiple addresses listed on it, even in mailto: URLs.
I think it would really be worthwhile for those people who are bothered so
deeply by spam to figure out what it is that I'm doing that they aren't
and see if it will work for them too. I don't get nearly enough of it to
hardly notice.
Perhaps that's the same for the other people who complain about munged
addresses?
> If someone wishes to post anonymously to avoid this, let them.
That's generally my opinion too, although I've seen and do not at all like
the negative effects caused by so many people munging their addresses, and
I think that solution is doomed in the long run.
> I can't see (in particular Tom C's) people's problem with people munging

It creates, in general on Usenet, the *expectation* that e-mail addresses
will not be repliable, which makes it much less frequent for off-topic
articles to be taken off-line, for side comments to be made in e-mail
rather than on the newsgroup, and for interesting discussions to come out
of small side-aspects of posts. Perhaps it's something that you have to
have been on Usenet for a long time to notice, but it's quite a loss to
the culture as far as I'm concerned.
> if you want to reply to them, do so in the same medium as their original

I'm not willing to do that, because a side comment to Tom about some quote
that he has in his sig may not have any Perl content and I don't see any
reason to post it to a Perl group. On this one, I'm afraid I'm fairly
hard-line, although I try to at least be polite about it. Those people I
know don't want to receive e-mail based on posts just don't get the
benefit of my side comments, which they probably don't miss anyway. :)

*shrug* I'm only getting 10-20 spam messages a week and you're getting
ten times that. I'm doing *something* right. ;)

I too perform a great deal of usenet postage, even if its somewhat seasonal.
I really don't think spammers are quite as discriminating as you suggest ;-)
A lot of it does, as I suggested, have to do with my above suggestion - some
ngs are just worse than others. I haven't received any increase in spam
whatsoever since I started posting to clpm, but some ngs are no-go areas as
far as I'm concerned. I don't post there anymore, but a.a is spammer
central, and a number of other ngs are similar - there could be any number
of reasons for this - maybe the spam bots prefer shallow hierarchies/
alphabetical accessability - alt.atheism is probably one of the first
groups a spammer trawling a ng listing would stumble across - c.l.p.m is
deeper hierarchially (eek! spelling!?) and alphabetically maybe??

I've been on Usenet for several years in various guises and I can understand
to a certain extent what you are saying, but I think that it is a matter of
striking a balance - remember I said that I support address munging, not
address exclusion - I mean that making your from: and reply-to: addresses
danCUTME@ReMoVE.fearsome.net is acceptable because it foils or at least
slows spammers whislt anybody trying to send you a message will see in their
"bounced" message that the mail was sent to danCUTME@etc - the real address
is obvious and they only have to hit "redirect" or "forward" in their mail
app. and all is well. Inconvenient, but every argument is considered.

Can't say I've been missing them myself ;-) and please don't mistake me - I
don't munge my own address in my headers/messages for the convenience of
others, and its always welcome in a conspiratorial kind of way when people
send an email to you on-the-side. I do, however, think that people have the
right to munge their addresses to avoid spam and that it shouldn't leave
them open to abuse from others.

Not arithmetic! There's not ten days in every week! ;-)

perl -de42
(Note that the 42 is irrelevant; perl -d invokes the debugger, which has
an interactive mode, but you need to give it some script to debug, and the
easiest trivial script is a -e script on the command line that's just some
simple number. And 42 is just appropriate. ;))

Better yet, go to http://www.skwc.com/essent and scroll down
until you get to my free cron reimplementation in Perl.
It's like having a real job scheduler on NT! :)
I use this for backups.

Sort of -- you must create a batch file, and CALL that batch file
after the script exits. There's no way for a called process to
change the env vars in the shell that called it.

Subject: Stopping a perl script from VB
Message-Id: <6rub9c$5dp$1@winter.news.erols.com>
What is the easiest way to stop a perl script running as an automation
object in VB. The script I am running parses large database style report
files, and would require a stop or cancel button in the VB interface that
calls it.
The script as it is currently structured is comprised of one main sub
which is exposed as a method to VB. This main sub is fed arguments from VB
and calls other subs within the script. Any help would be appreciated.

I'm afraid that you'll find it very difficult to get rlogin to work (or at
least you *should* find it difficult to get it to work), since rlogin,
like any program that prompts for a password, should explicitly reopen
/dev/tty and read from it, specifically to prevent people from doing
things like this. ;)
If the user knows the password for the generic ID, can't you just put that
user @localhost in a .rhosts files for the generic user, so that rlogin
won't prompt for a password?

Administrivia:
Special notice: in a few days, the new group comp.lang.perl.moderated
should be formed. I would rather not support two different groups, and I
know of no other plans to create a digested moderated group. This leaves
me with two options: 1) keep on with this group 2) change to the
moderated one.
If you have opinions on this, send them to
perl-users-request@ruby.oce.orst.edu.
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your
article to perl-users@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
The Meta-FAQ, an article containing information about the FAQ, is
available by requesting "send perl-users meta-faq". The real FAQ, as it
appeared last in the newsgroup, can be retrieved with the request "send
perl-users FAQ". Due to their sizes, neither the Meta-FAQ nor the FAQ
are included in the digest.
The "mini-FAQ", which is an updated version of the Meta-FAQ, is
available by requesting "send perl-users mini-faq". It appears twice
weekly in the group, but is not distributed in the digest.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
