[ 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://www.cpan.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://www.cpan.org/
http://www.perl.com/CPAN/
http://www.cpan.org/doc/FAQs/FAQ/html/
http://www.perl.com/CPAN/doc/FAQs/FAQ/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.)
California ftp://ftp.cdrom.com/pub/perl/CPAN/
Texas ftp://ftp.metronet.com/pub/perl/
South Africa ftp://ftp.is.co.za/programming/perl/CPAN/
Japan ftp://ftp.dti.ad.jp/pub/lang/CPAN/

Netherlands ftp://ftp.cs.ruu.nl/pub/PERL/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
more information on doing that, send mail to <mail-server@rtfm.mit.edu>
(not to me!) with these lines in the body of the message, flush left:

This will, of course, only work if the current working directory is the
directory where the executable lives. If he's running this from CGI
(which is my guess, since he talks about telnetting to a directory,
which is sort of like pedaling an orange) his current working directory
may be random.

Make sure you fix the quote on here before you try to run it.

Subject: how to change order files from readdir
Message-Id: <7s5c7e$evd$1@news1.xs4all.nl>
I use readdir to get list of files in a directory. When I do this the files
seem to be ordered alphabetically. Is there a way to change the way the
files are ordered, for example on size?

readdir doesn't guarantee any ordering at all, though alphabetical is
typical. If you want to reorder the list, you'll have to do it yourself
once you've got the filenames.

but could you clarify why you said that, please? Is there something
fundamental that I've missed, or is your concern based on the higher
risk of getting the configuration wrong for that lower level
subdirectory?
> Data files should live somewhere away from the URL tree, whtaever it may be.
Ah, I think you're concerned about the risk of "data" files being
accessed directly through the web server, instead of via the cgi scripts
as intended. Well, sometimes it's desirable to offer both.
If those data files were htpasswd (for example) and friends, then I
would tend to agree with you. Although it's possible to configure a web
server to deny access to those files even within the web tree, it's
surely safer not to leave oneself open to the risk.

Depends on ones definition of below. I meant any other directories on the
cgi-bin path. Eg. cgi-bin/another_dir/data_file. Some may be refer to this
as above. I get confused, I know what I meant. That unfortunately only
helps those with the legendary PSI::Esp module.
Mind you putting data files in the dir immediately below(above) cgi-bin on
most systems is even worse. It's generally the base URL directory of the
site, and everything tends to be accessible there.

Hello,
I`ve the following problem creating a lists, that contains lists:
push(@array1,@array2);
pushes every element of array2 as one element on array1, but not the
hole list/array as one element.
I hope this is possible without using references (because I have to puth
several lists on array1 that way, and build these lists by just one
loop.)
thanks

I use deja.com for my newgroups and was just reading a message and i saw
a link in the message. the link appeared as:
merlyn@stonehenge.com
When i clicked on the link i got a deja.com internal server error so i
looked at the actual url within the link and saw this:

I am sure this is not how the original poster coded the anchor adress.
It is not ethical to alter data in a usenet post (and if you're going to
do it the least you could do is make it work). this is alot different
from putting a tag at the end of somebody's message that was posted
through their system, that is fine, changing data in the actual message
is not.

The Perl Resource Kit (which I finally found) contains all
manner of documentation on modules, including usage and
programming.
It may be difficult to find at this late time though, as
it has gone out of print.

Subject: s/// conditional substitution
Message-Id: <7s5ele$ca98$1@pike.uhc.com>
hi,
i would like to perform a conditional substitution based on what $2
matches. is this possible in one stmt?
# this is sorta what i want to do, the results follow:
if ($subsetCriteria[$X] =~ (s/(.*) +(in|ex)clude +'?(.*)\b'?\s+(.*)/$2 =~
\/in\/ ?V:^(_RC$Ctr = '1') $4/))
# results, :
in =~ /in/ ?V:^(_RC1 = '1') &
# desired results:
^(_RC1 = '1') &
# or
V(_RC1 = '1') &
###################################################################
# these stmts work but i dont like accessing the string twice
if ($subsetCriteria[$X] =~ (s/(.*) +(in|ex)clude +'?(.*)\b'?\s+(.*)/(_RC$Ctr
= '1') $4/))
{
if ($2 =~ /ex/)
{
$subsetCriteria[$X] =~ s/\(_RC/^\(_RC/;
}
is there a way to make it do what i want and not what im telling it to do?
am i niggling this point?

Notes
=====
- A line in the body of a post is considered to be original if it
does *not* match the regular expression /^\s{0,3}(?:>|:|\S+>|\+\+)/.
- All text after the last cut line (/^-- $/) in the body is
considered to be the author's signature.
- The scanner prefers the Reply-To: header over the From: header
in determining the "real" email address and name.
- Original Content Rating (OCR) is the ratio of the original content
volume to the total body volume.

Message-Id: <937834693.380537@diddley.primus.com.au>
Hi,
I'm trying to specify a target frame in a URL redirection...
My guess doesn't work:
$go="http://www.URL.com/index.htm ";
print ("Location: $go\n\n" target="4_display_area");
How should I format the line?
Thanks,
Wes

From: "Robert W. Byrd" <tech@tburg.net>
Subject: Thank you
Message-Id: <37E62479.D704DCD0@tburg.net>
Is this on-topic? Don't know... it is about Perl though...
At the risk of having a herd a camel lovers torch me for using
up bandwidth in their newsgroup, I present the following:
I have been reading this newsgroup for about three weeks now
and have seen all manner of questions, answers, and other
remarks. Some good, some not.
Perl is a remarkable language. The work started by Larry and
continued by rather large handful of others (you know who you
are... I'm not going to list names for fear of forgetting
someone) is somewhat awe inspiring.
The fact there are so many books dealing with Perl is also a
testament to it's fame and popularity (and I have purchased
nearly all of them!)
Very seldom does an end user have the opportunity to communicate
with the people who have worked on and enhanced a language like
we are able to in this newsgroup.
So... to all of you who have contributed not only to perl, but
also to this newsgroup, I offer my thanks. Without you, this place
would be nothing but a slim shadow.
"Kudos to you all!"
Respectfully,
.rob.

Message-Id: <null>
Administrivia:
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.
| NOTE: The mail to news gateway, and thus the ability to submit articles
| through this service to the newsgroup, has been removed. I do not have

| abusing the service, and I no longer have any desire to waste my time
| dealing with the campus admins when some fool complains to them about an
| article that has come through the gateway instead of complaining
| to the source.
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.
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.
