Perl, as far as I know, has no limitations on file sizes, however, Unix
in its many flavours does. Solaris used to have a file size limitation
of 2gb, open or not.
I don't deal much with AIX these days, but a brief search brought up the
following. I'm guessing that you are using 4.2 or better so you might
try "ulimit -f unlimited" to increase your resources. Also, I found
http://www.rs6000.ibm.com/doc_link/en_US/a_doc_lib/aixprggd/genprogc/prg_lrg_files.htm
to be very good in explaining your quandry. You might share it with your
SA :)
"The AIX 4.1.4, 4.1.4.1, and 4.1.5 file system data structure is based
on the 32-bit addressing scheme, pointers, data blocks, and so on.
Therefore 2 to the 31 power which is about 2 GB, is the maximum file
size allowed.
AIX 4.2 will support 64 bit addressing, and at that time the maximum
file size will greatly exceed the 2GB limit. In order to support file
size over 2 GB, you need to wait for AIX 4.2.
The 'ulimit' command can be used to set or examine the resource limits
including the file size. The example below, would set the maximum file
size to 4,194,304 blocks (512 Bytes/block) which is 2GB, the limit:
ulimit -f 4194304
If you set ulimit -f to this value, the it will show "unlimited" which
is the maximum. The default file size is set to 2,097,151 blocks (1 GB)."

Subject: Conditional Using Regular Expression
Message-Id: <37B4BEF5.DB453037@LA-Online.com>
I am fairly new to perl, and am writing a web client that will return a
list of links based on a conditional match. I don't have much
experience with regular expressions, and have been unable to get a
match.
I want to write a conditional using a reg exp that matches 4 constant
characters, 4 variable digits, a variable alpha, and '.htm' like so:
food1111a.htm
Here is the syntax that I'm trying to use:
if ($linkURL =~ /food......htm/i)
{
print "<A HREF=http://www.food.com/recipes/$linkURL>$linkURL</A><BR>";
}
For some reason, this isn't matching, and what I'm trying to determine
is whether I am using reg exp incorrectly. I've tested
$linkURL, and it seems to be pulling what I expect it to pull.
TIA

Why are you still participating in the perl groups when you don't read

Tom _can_ be a pain, but I am willing to tolerate that from one of the

Can't agree with that. Just because someone get's something wrong doesn't
mean that you should be abusive towards them. Ok, so you don't /have/ to be
polite, but when has being polite harmed anyone?

I cannot agree with that. How hard is it to be polite. Sarcasm I can take, I
am myself sarcastic. But pointless abuse? Why?

Yes indeed, your behaviour was totally unacceptable: you treated us all
abominably. So don't ask FAQs again, and then we won't have that

Yeah, I couldn't find a reference to Unicode in the documentation either.
But according to the Perl Cookbook (p. 3), the current version of Perl
doesn't support Unicode. Perl's 'locale' pragma (see the perllocale
manpage) offers support for POSIX locales, for different single-byte
character alphabets, but as far as multi-byte characters are concerned, I
believe it's largely roll-your-own.
Good luck!

I think it really comes down to what "attractive" means. I suspect what
you really mean is that the sites in question are visually plain. If the
site's intended audience is people who are looking for specific
information, as opposed to those who are seeking an "experience," then a
visually plain design is often the easiest one to use.
Second, in Web-as-media terms, "visually attractive" really means
"visually attractive to upper-middle-class white suburban American males
in their late teens or early twenties whose visual sensibilities have been
shaped by video games and MTV"; this happens to be the demographic that
most Web-as-media designers come from. Someone who doesn't come from
that demographic and isn't making a specific effort to target that
demographic is unlikely to have production values based on flashiness and
busyness.
Finally, keep in mind that the more significant the actual content of a
site is to the reader, the less presentation matters to the reader, as
long as the presentation doesn't get in the way of accessing the
content. Most programming-related sites are quite content-heavy.

But why should it appeal graphically? I hate pages that go "You need
Netscape or IE to view these pages", "You don't have java turned on".
I'm trying to use the Web as a source of information (which, IIRC was
the original intent of HTML?), not as a way to make my machine crawl
as it compiles/interprets x lines of code to present me with a pretty
menu.
Yes, I'm one of those crazy people who surfs with Lynx when I
want information. Sure, I have Netscape, but it annoys the crap out
of me on both Windows and Linux. And don't even mention IE to me.. I
have enough of a dislike for Windows without including that..
Unfortunately, it appears that 99% of the websites out there are
designed by either a graphic artist who has no clue how to use the ALT
part of the IMG tag properly, or by people in marketing.. I'm not sure
which is worse. Even the new www.perl.com has an error (*) or two in
Lynx, but it beats some others I've seen.
* Error(s):
Load the page in Lynx, look in the upper left. Why do I need to know
that blank.gif is there? Or anywhere else that the phrase blank.gif
occurs? "bullet"? Whats wrong with "*"?
The IFRAMES which I think are meant to be a pair of links are actually
4 links due to line breaking somewhere.. this might just be Lynx doing
something wierd.
Unfortunately, I can't think of an ObPerl..

I'm having a problem with a perl script. The problem
we are having is with the E-mailing of information to a
client. To make it simple, the script that sends an Email
to someone when they enter their address (Mary Smith in

lines for sending the mail:
...
open(MAIL,"|$mailprog -t");
print MAIL "To: Mary Smith\n";
print MAIL "From: John\n\n");
print MAIL "Subject: Information\n\n";
...
When the Email is received by the person however, the "From"
field reads not "John", but "John@whsun626.webhosting.com"
How do we get rid of the extra server info following the name?
We've tried a few things but it always reads the same.

Seems more like a problem with your news reader as people have responded
to this question before. Since you post with Deja why not search on
your name and see the responses.
Ask you system admin for help.

Since you mention lpt1, I'm assuming you're talking about a Win32
system. On at least some versions of Win95, output from a program
invoked by a batch file (which is how perldoc is implemented on Win32
systems) can't always be redirected. You might try:
perl \perl\5.00502\bin\perldoc.bat perldoc >lpt1
(put in the correct path to perldoc.bat for your system) and see if that
works.

Right. I'm trying to learn more here about the regular expressions.
And I have, thanks.

And if you use an editor with a Python mode (plenty of those), you press
'tab' a few times to make it indent properly and you get another error,
because there's:
print "a is" a
which isn't valid.
I didn't get the error. A good editor is definitely helpful.

Well, what if I get abhorrent feelings because I forgot a close } somewhere
and it gives me an error? :) I maintain the whitespace argument against
Python is a strawman argument. I've been coding in Python for about a
year now and I don't recall ever having been bitten by this problem.
I've used Emacs, jed, and even some vi and windows notepad.

I didn't find it so, but of course this can happen. These days I tend
to blink a couple of times wondering what these }'s are about in
languages like C++.
But agreed, people are different. Perl didn't click for me, Python did. It
may be the other way around. Long live diversity, just as long as I
don't have to deal with _too_ much Perl code. :)

Why are '{' and '}' mandatory in Perl? Why isn't Perl permitting the
programmer to leave them away? I can add #{ and #} delimiters to Python. :)
But editors that grok Python are definitely helpful, granted. But it's the
same for Perl; editors that grok that } closes { are definitely helpful.
Using both { and } and whitespace to mark block structure is redundant.
Perl and many other languages choose to make whitespace optional; now
you can write compact but difficult to read code. Python chooses to make block
delimiters optional. The advantage is that your code can't be that particular
kind of unreadable anymore -- the disadvantage is that you always have to
indent properly. This turns out not to be a very large disadvantage. The
disadvantage is in my opinion smaller than the advantage of not having to
maintain convoluted non-indented code, and the advantage of not having to
deal with unfamiliar indenting styles and 'how to indent' flamewars. :)

Martijn

Unbelievably stupid subject, eh? I certainly thought so when it was
shoved at us. The flame war begun in comp.lang.perl.misc isn't doing
anyone any good, and then coming over to comp.lang.python to stir up the
shock troops to send in a few commandos is even worse. I don't think
you'd like it if we in comp.lang.perl.misc sent 100,000 script kiddies
over to comp.lang.python to rant at you guys about how K31L they though
Perl was and how L@M3 they thought Python was.
Do you want to learn or do you want to flame? Learn? Really? Ok, here's
all you have to do. Go write a medium-sized program comprising many
hundreds of lines, broken up into several files and selectively imported,
but do so in whichever language you know the *least*. That's the way
to learn, not though wars. There's no way we can learn from one another
by flaming. And there's plenty to learn. Everyone should do this.
Please and thank you.
