I'm not sure if I was included in your list of morons, but I did
use the word "elitist" to Tom, so I'd like to clarify things a
bit.
I only responded to a post about munging FROM addresses. That's
the only one I do not agree with him on - for reasons stated in
that post, which I will not repeat. That whole post was *only*
about that and nothing else.
The word "elitist" was only with respect to the fact that not
everyone *can* have as effective sp am filters as he does. (I
can, and do. I wasn't even speaking for myself there...)
ON *ALL* OTHER ISSUES (FAQs being asked for the nth time, CGI
questions being asked here, bad subject lines, etc.), I agree
wholeheartedly with Tom and indeed my sympathies are with him and
Randal and the other gurus in this respect.

Message-Id: <34E482D3.CC0EBD4D@ixlabs.com>
I'm building Perl 5.004_03 on a Sparc Solaris box - having lots of
trouble though....
gcc 2.7.2 is in /usr/local/bin/gcc
as, ld are in /usr/ccs/bin
All of these binaries are found in these location first in my PATH as
confirmed by which(1).
I've compiled a "hello, world" with gcc so I know that at least pretends
to work...
But Configure keeps complaining that I am not using /usr/ccs/as & ld,
and that these are the GNU versions which won't work....
I know these aren't the GNU versions because they don't accept --version
as a command line parm (as the GNU versions on my Linux box do).
And if I ignore this warning, Configure will give me a whoa! and tell me
my compiler isn't working...
What am I doing wrong? I've never had this much trouble building on
Sparc Solaris.

With recent perl distributions there's a constant module so you can say
use constant x => 10;
and use x (no $) in your code. The perldoc documentation includes this:
use constant PI => 4 * atan2 1, 1;
[...]
These constants do not directly interpolate into double-
quotish strings, although you may do so indirectly. (See
the perlref manpage for details about how this works.)
print "The value of PI is @{[ PI ]}.\n";
If you have an older perl 5 then you can use this trick to make a
read-only scalar:
DB<1> *x = \10
DB<2> print $x
10
DB<3> $x = 3
Modification of a read-only value attempted at (eval 8) line 2, <IN> chunk
3.
but the a recent release with the constant module is my route of choice.
Hope this helps,
Mike

Self-protection is not necessarily hiding. It can also be the first

The single-user thing is a red herring.

Usenet is too much of a time waster. I'm seldom here (though when I'm

Dave,
I'm sorry that you spent so much time, money, and effort to get an
answer to your question. I wonder if there is a way you could get the
same repsonse with less effort next time? If not, I wonder at least if
there is anything we can do to help others from your experience.
To help yourself get a better response next time. Here are some ideas.
You might want to spend a little more effort in making your subject
line inform people about your request. Instead of "Subject: How the
Hell do I...?" how about "Subject: Deleting a File." For a two week
search, maybe you could spend another two minutes trying come up with
a concise description of your problem.
My guess is that $150 dollars in books accounts for three to five
different titles. Did you find anything at all close to what you
wanted? Anything about files at all? If you describe where you have
looked so far, it diffuses a lot of flames. Even if you are off the
mark, it at least shows that you made an effort, and where your search
has gone wrong. "In the book "Plumbing Perl in 21 Days", I see entries
on how to open and close files. It says nothing about how to delete
them. I did see the function named "delete", but it doesn't seem to do
what I want."
And now in the catagory of helping others. Now that you know how to
delete a file, can you see where the books that you purchased are
misleading in how to delete files. Is the index incomplete in any
regard? I know most of the books that I've purchased recently have
e-mail addresses for both the publisher and the author. Maybe now that
you have the solution, you can spend a couple of minutes to describe
to them the shortcomings of the book. Hopefully these shortcomings can
be addressed in later printings of the book and others won't have to
go through the same experience.

Because you need to give the location as a complete URL, with the
http:// and all.
: doesn't redirect my browser to Yahoo!, but instead gives a 'Document

: perfectly. Returning HTML works perfectly. But for some reason,
: redirects like the above don't work from perl scripts...
Have you looked at the C++ sources? I bet the line with the location
is sprintf( "Location: http://www.yahoo.com\n\n" );
Anyhow, this is a question which really relates to web servers, although
perhaps you didn't know that. When using any HTTP headers in code, be
sure that you have formed them correctly.
Also, comp.lang.perl is no more :)
In the future, be sure it is a perl question you are asking, and if it's
not, then post to the "correct" newsgroups
(like, comp.infosystems.www.authoring.cgi, in this case)

That would then be MS Visual PPP, or just PPP (to be confused with the
Point-to-Point Protocol PPP). Didn't you see that last week, Bill Gates

If I might make a suggestion to the "powers that be," who administer
this NG, maybe it might cut down a little on the nuisance posts.
At the end of each message to comp.infosystems.www.authoring.cgi, there
is a little disclaimer message. I have no idea how that is done
(actually, I have some idea, but it is rudimentary). Perhaps a sentence
or two at the end of every post here can be set, directing new readers
to Nathan's NG FAQ, particularly if it could be archived at perl.com or
another suitable place. Nathan's FAQ, even though it is posted 2x week,
gets drowned in the noise just like every other useful post.
I don't expect this in my wildest dreams to solve the problem, but maybe
it would cut it down somewhat and we could get back to the interesting
issues, like uses of old punchcards (was one of the perennial Y2K
threads, but has mutated for the better, IMHO).

Its sort of a 'Usenet Cultural' background problem. I supose for a
_technical_ oriented group, moderation isn't so bad. Perhaps a sort
of robo-moderation like in the c.*.cgi newsgroup.
My first exposure to moderation was soc.feminism, which probably wasn't

It did, but it's been a couple of years. The last time I saw an lwall
post here was about Aug-Sep '95, but by then it was pretty uncommon. I would
frequently see him in comp.lang.perl -- was it about the time 5.001m was
put out (early '95) that it split?
I believe he stopped reading much here by the end of '95. Much of
the discussion that used to go on here has moved to perl-porters.

When I post to c.l.p.m, I usually spend a lot of time on the Subject
line, since a lot of people (including me) will make their decision
about whether to read a post based only on that. So I try to make it
concise but informative, and generally just as "professional" as
possible. Hopefully it works somewhat.
I agree, by the way, that a moderated group is a good idea.
comp.lang.c++.moderated seems to work well.

It would probably be easier to create comp.lang.perl.moderated and
leave this group extant. A similar thing was done in the sci.physics
hierarchy (adding sci.physics.research as a moderated group) and it
seems to have worked out fairly well.

Subject: opening files in subroutine
Message-Id: <01bd3897$b1b83ae0$316845c2@xkn14>
could someone please tell me how to open the second file ( $groupd )
once the subroutine has finished with the first or should i just make
two calls to the routine one for the first file and one for the second. In
addition is there an easy way to tell if any of the groups
in @addgrps were not found in either file - i could delete them if
found with an associative array - how do i pass this to a subroutine.
any advice would be very much appreciated
jon marshall
#!/usr/bin/perl
#
$groupf = "group";
$groupd = "group.dataserv";
sub updategrp {
local($newuser,$groupf,$groupd,@addgrps) = @_;
open(GRP, "$groupf");
open(GP, ">>${groupf}.bak");
while (<GRP>) {
foreach $addgp ( @addgrps ) {
if ( /^$addgp:.*:$/ ) {
s/(.*)/$1$newuser/;
} elsif ( /^$addgp:.*[^:]$/ ) {
s/(.*)/$1,$newuser/;
}

print GP;

close(GP);

Since the quoting mechinisms for COMMAND.COM are different than for
the common unix shells, you can't write one liners the same
way. Notice, this is a COMMAND.COM limitation and there is nothing
that perl can do. The command line is already garbled and can not be
recreated. Basically, COMMAND.COM does not allow single quotes to join
multiple words together as a single argument, so perl sees 'print as
the -e script, and Hello\n;' as the first argument.
The solution is to write your "-e" script fragments in a way that that
is proper for the command line interpreter you are using. The perlrun
man page shows how to to do this for various non-unix ports of perl.
One suggestion not mentioned in perlrun, but one that I find useful is
to use the alternate quoting operators in the perl scripts, so that
you can leave COMMAND.COM's notion of quoting alone. I'm talking about
perl's ability to use things like qq#string# or qq(string) for a
double quoted string. See the perlop man page for details.
C:\TMP>perl -e "for (@ARGV) { print qq($_\n)}" 'print "Hello\n;"'
'print
Hello\n;'

Please don't waste our time witha question that has been asked a bazillion
times before. For example, go to Deja News <http://www.dejanews.com> and
enter:
Perl compiler
In the quick search box. I got 1185 matches back.
Please do a little research before you post a stupid question. It took me
15 seconds to search Deja News...

Message-Id: <887384946.393740289@dejanews.com>
Hi,
I have to write a cross-OS benchmark perl script, with a resolution
of some milli-secs. I saw Time::Hires on CPAN but it is not usable
on NT :
Did any code some kind of similar module, available for both NT and
Unix ?
TIA

Subject: Question concerning backreferences
Message-Id: <6c1vhk$1enu@cortez.sss.rpi.edu>
I was writing a small program today, and I was doing a bit
of regexp'ing. Rather than deal with defining another
variable, I decided to try to modify $1 directly, since it
was holding the data I was looking for. Perl dies out,
complaining about trying to modify a read-only variable.
"Read Only?" I say, and open my camel book. Yup, sure enough,
under its definition, they are read only. Browsing through
the FAQ, I didn't notice anything concerning this topic, so
I decided to risk the killfile and ask this question: Why?
Probably for a good reason, but since I'm in a curious mood,
could someone give a -v answer?
(Tom, please don't *plonk* me! I use a real OS and a real
newsreader! *chuckle*)
Thanks.

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.
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.
