Is this on your own server, or an ISP/hosted server?
If it's on your own server, just issue the command at the command prompt.
If it's on the latter, then you will have to find out from them how to go
about doing
it. If you have a shell account for your server, then just telnet into it,
and then issue the command.
hope this helps,

I've seen this now a couple of times. The Win32::OLE module from libwin32-0.14
doesn't seem to work with the Borland compiled 5.004_02 distribution. I've
compiled both 5.004_02 and libwin32-0.14 with MS VC++ and everything works
fine. I did send a bug report to Sarathy about it, but I guess it is on low
priority for him.
The best way would be to switch to ActivePerl. It is based on a recent version
of Perl and also already includes the latest Win32::OLE module.

Subject: background process module - STDIN/STDOUT/STDERR?
Message-Id: <7bv161$ne2$1@nnrp1.dejanews.com>
Hi-
I'm working on a system independent background process module to handle
parallel program runs. Initially this is for a make-style build system,
but I've got a lot of simulation stuff that will benefit from a system
that can manage parallelism.
I looked over the various process modules in CPAN, and all of them missed
on the functionality I was trying to get. Perhaps most importantly, the
module will support both Unix and Win32, which means a fork/exec model
for starting processes isn't always available.
The model of operation is:
# start a job
$handle = Subproc::Create( @args, %env );
# reap any available child
$handle = Subproc::Wait( );
# reap a specific child
$handle = Subproc::WaitPid( $handle );
In general I'd like to let STDIN/STDOUT/STDERR "take care of itself", but it
doesn't seem to be. My test.pl script runs "/bin/ls -l" and waits for it
to finish, all of which works quite nicely. However, after the first
Subproc::Create(), STDOUT seems to be screwed - output gets swallowed,
and just before the test finishes a "11" is barfed out on stdout. If I do
all my perl printing to STDERR, that works fine. I've tried using
$|, but to no avail.
Any suggestions? The module itself is living in
http://graphics.stanford.edu/~eldridge/temp/subproc-0.01.tar.gz
Thanks,
-Matthew

It really looks like you're trying to do Proc::Background again - from
the man page:
use Proc::Background;
timeout_system('seconds', 'path_to_program', 'arg1');
my $proc = Proc::Background->new('path_to_program', 'arg1', 'arg2');
$proc->alive;
$proc->die;
$proc->wait;
$time = $proc->start_time;
$time = $proc->end_time;
And it supports both Win and Unix.

How do you do it when all the names are present in all files?
Maybe we could look at your code and point out some simple changes to
make it work with the non-comprehensive input files.

Have you tried Deja News or Alta Vista? Those are the best

You'll probably want to trim that down a bit, though.
ftp.cis.ufl.edu:/pub/perl/comp.lang.perl.*/monthly has an almost
complete collection dating back to 12/89 (missing 08/91 through
12/93). They are kept as one large file for each month.
You'll probably want more a sophisticated query and retrieval
mechanism than a file listing, preferably one that allows you to
retrieve articles using a fast-access indices, keyed on at least
author, date, subject, thread (as in "trn") and probably
keywords. The best solution the FAQ authors know of is the MH
pick command, but it is very slow to select on 18000 articles.

Where can I buy a commercial version of Perl?
In a real sense, Perl already *is* commercial software: It has a
licence that you can grab and carefully read to your manager. It
is distributed in releases and comes in well-defined packages.
There is a very large user community and an extensive literature.
The comp.lang.perl.* newsgroups and several of the mailing lists
provide free answers to your questions in near real-time. Perl
has traditionally been supported by Larry, scores of software
designers and developers, and myriads of programmers, all working
for free to create a useful thing to make life better for
everyone.
However, these answers may not suffice for managers who require a
purchase order from a company whom they can sue should anything
go awry. Or maybe they need very serious hand-holding and
contractual obligations. Shrink-wrapped CDs with perl on them are
available from several sources if that will help. For example,
many perl books carry a perl distribution on them, as do the
O'Reily Perl Resource Kits (in both the Unix flavor and in the
proprietary Microsoft flavor); the free Unix distributions also
all come with Perl.
Or you can purchase a real support contract. Although Cygnus
historically provided this service, they no longer sell support
contracts for Perl. Instead, the Paul Ingram Group will be taking
up the slack through The Perl Clinic. The following is a
commercial from them:
"Do you need professional support for Perl and/or Oraperl? Do you
need a support contract with defined levels of service? Do you
want to pay only for what you need?
"The Paul Ingram Group has provided quality software development
and support services to some of the world's largest corporations
for ten years. We are now offering the same quality support
services for Perl at The Perl Clinic. This service is led by Tim
Bunce, an active perl porter since 1994 and well known as the
author and maintainer of the DBI, DBD::Oracle, and Oraperl
modules and author/co-maintainer of The Perl 5 Module List. We
also offer Oracle users support for Perl5 Oraperl and related
modules (which Oracle is planning to ship as part of Oracle Web
Server 3). 20% of the profit from our Perl support work will be
donated to The Perl Institute."

You may take a look at http://www.pault.com -> Perl Application
Server. The design is that there is perl script running forever
(server) and there are clients ( perl scripts, java or c programs,
e t.c. -) , that can ask server to invoke any (preloaded) perl function,
re-reading those functions on-fly when the'r changed ( allows easy
debugging ). Works on any UNIX and Windows as well. Pure perl
solution.

For many tasks fast-cgi is better than mod_perl. With mod_perlyou have perl
executable / script running with each instance of
Apache ( eating resources, hard to sync e t.c.) Perl Application
server is closer to fast-cgi, but is _much_ more flexible.
> > Would this be an approach in words of performance ???
Sure. Not only invoking perl executable eats the preformance,
but perl's compilation to bytecode, re-opening database
connections / handelrs e t.c. usualy causes significant
slowdown. It's why fast-cgi and similiar solutions are
so popular.
About running perl interpreter as a service is not a big
deal with srvany or similiar stuff. I wrote my own trivial
'cron' for NT in 2 days, using MS example of the service.
The problem is resanoble API with such perl service.
I don't understand the advantages of such solution for
the real life. If you want fast CGI's - use existing solutions.
If you want 'fast perl script but not CGI on NT box' ...
Can't imagine the real task ...

Subject: newbie problem with *s (regular expression matching in win32)
Message-Id: <36e3072d.180341868@enews.newsguy.com>
In "Learning Perl" (The llama book), there is an exercise in chapter 7
that says to create a regular expression that matches "any number of
backslashes followed by any number of asterisks (any number might be
zero)"
I thought to use /\\*\**/ which is also the answer given in the book.
When I tested it I didn't quite get what I expected:
$_ = 'fff\\\\****';
/\\*\**/;
print $&;
There wasn't a match. The f's are just thrown in as filler.
If I tried /\\+\*+/ the print statement returned the expected match:
\\****
I took out the f's, and then suddenly it worked correctly with the *
pattern. It also didn't matter if there were f's or a's or my name,
scott, at the beginning of the string -- the * grouping pattern
didn't work.
I saw similar results when playing around with expressions like a|b*;
that didn't work but a|b+ did.
I'm using 503 and downloading 509 to give that a try, but I think the
problem may be more due to my rudimentary understanding of Perl than a
bug in win32 Perl.
Can anyone tell me what I'm doing wrong?
Thanks,

Does anybody have any idea about why I get this error? The script runs
fine as a script. Even though perlcc is in it's first release form (as

There's probably a better place to post this but all I can do is
reproduce the error, I have no idea why the latest libwww bundle

is messed up somewhere in the response handling. I'm testing this on
multiple Win32 systems but I have a suspicion the problem will repeat on
other platforms. I've tried both the GS and AS ports of Perl, the only
thing that works is reverting to an older bundle of libwww. None of the
documentation or FAQs was of any help and a search on DejaNews and
various mailing list archives turned up squat.
I'd really like to use the latest libwww bundle but I am not able to
because of this annoying issue.

# This script works fine on earlier releases of libwww bundle

Look for documentation on Unix termios library. In Perl, it is part of
the standard POSIX module. If the termios man page makes little sense,
take a look at the book "Advanced Unix Programming", by W R Stevens.

The examples are in C, so you've have to translate its concepts to
perl yourself.

Well, after 6 months, here's the answer to the quiz: what do we do about
comp.lang.perl.moderated. Answer: nothing.
]From: Russ Allbery <rra@stanford.edu>
]Date: 21 Sep 1998 19:53:43 -0700
]Subject: comp.lang.perl.moderated available via e-mail
]
]It is possible to subscribe to comp.lang.perl.moderated as a mailing list.
]To do so, send mail to majordomo@eyrie.org with "subscribe clpm" in the
]body. Majordomo will then send you instructions on how to confirm your
]subscription. This is provided as a general service for those people who
]cannot receive the newsgroup for whatever reason or who just prefer to
]receive messages via e-mail.
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.
