As Benjamin already said, glob is your friend.
However, you should note that the backticks returns
in scalar context a string with all the multilines of the output,
while in list context it returns a list consisting of the lines of the
output.
Thus it is unnecessary to split the result of the backticks to gain the
different lines,
just use
my @array = `...`;
instead of my @array = split /\n/, `...`;

Janek

Yes, this does work and by doing a foreach over the array can remove
the unwanted bits. But now I have to learn about glob :)
I ended up with:
opendir thisdir, 'c:\\seismo\miniseisnet\\';
@array = grep { $_ =~ /\.station/} readdir thisdir;
close thisdir;
I guess my biggest question is why it work on one computer and not on
another. I was hoping that this code would be portable at least
between windows machines.

I find that most people think, "how hard can it be?"
They find their hand rolled code seems to work for all the situations they
use it in, so they assume it works well for all situations.

But "why?" Why do people, beginners no less, constantly
want to write this themselves when using the CGI module
is almost infinitely easier (not to mention better).
This applies not only to CGI.pm, but to modules in
general. Why are so many people reluctant to
use modules? It puzzles me.
Would the same people insist on writing a custom
printer driver for every piece of software they use?
Why not use the ones that come with your OS?
Does every Java programmer go around writing
the swing library from scratch?
Do C++ programmers start out writing the
equivalent of the STL before writing a program?
Are C programmers too proud to start their programs
with #include stdio.h and insist on writing
it themselves?
What is wrong with people?

I suspect it is because there are so many existing scripts and tutorials
that don't use the CGI module.
Also there is a lot of FUD about the overhead of using modules.

Speaking personally, I tried to avoid using non-standard modules in my
software that I distributed, as I found that beginners would get very stuck
trying to install a required module. However, I changed my mind on that
one, and just include local copies on the modules my software uses.
Sure it makes the distribution a bit bigger, but it certainly makes
development much easier.

Possibly...at least as long Perl is concerned. I was lately working with
a larger database (initially mysql). It turned to be out that Perl was
always much quicker than the underlying database and was most of the
time waiting for mysql to finish its queries.
To make the overall application quick enough you likely need some
optimization strategies. That's database-dependent. For instance, mysql
can be sped up on UPDATEs if you make a lot of them in a row instead of
mixing them with SELECTs. Consult the documentation of your database for
such matters.

I found something you might be interested in(I know I am). A quick
search on CPAN led me to Emacs-EPL. It contains three modules:
- Emacs Redefine Perl's system primitives to work inside of Emacs
- Emacs::EPL Protocol implementation and data conversions for Emacs Perl
- Emacs::Lisp Support for writing Emacs extensions in Perl
The description for Emacs::Lisp reads:
Emacs allows you to customize your environment using Lisp. With EPL,
you can use Perl, too. This module allows Perl code to call functions
and access variables of Lisp.
There is no ppm package for it(I assume you are running AS Perl since
you are using Windows) - at least not for the version I'm
running(5.6.1) - but it make's and installs fine using nmake .
I'm running GNU Emacs 21.2.1 on Win2K. The docs say it will work in
XEmacs as well.

Message-Id: <b5rtfg$icd$04$1@news.t-online.com>
Hi folks,
I have a very big application written in perl and would like to use some of
my shared object c++ libs (.so) with it and would like to replace the
perl-code part by part by c++.
Is this possible and if yes, how? (I think on a win32 system I can use the
win32::API for it, right?)
If you have done that before, I'd be very thankful for some hints how to
avoid common mistakes etc.
Many thanks in advance,
yours Henri

Apparently not, but there is File::Rsync.

Agreed - my mistake! - I am wearing sack-cloth and ashes even as I type.

That depends - they were where my team and I started - but then our history
was with 20+ years of C and unix - it all depends on the starting point. I
take your point though - for a total novice they start too deep. For
someone transferring from another language they're fine (they were for me,
anyway).

Why do you need to fork? Assuming you're using CGI.pm, what you try to
do should be possible without forking?
[ snippet from CGI.pm : ]
There are occasionally problems involving parsing the
uploaded file. This usually happens when the user presses
"Stop" before the upload is finished. In this case, CGI.pm
will return undef for the name of the uploaded file and set
I<cgi_error()> to the string "400 Bad request
(malformed multipart POST)". This error message is designed
so that you can incorporate it into a status code to be sent
to the browser. Example:
$file = $query->upload('uploaded_file');
if (!$file && $query->cgi_error) {
print $query->header(-status=>$query->cgi_error);
exit 0;

I think it's confusing AUTOLOAD; I'm not sure *why*, though.

Subject: Simple CGI Select by Date

I've little experience of CGI and Perl, but I need a script that will
build a Web page taking mostly static html, and selecting some table
data from a text (or xml) file based on a date field (or equivalent
numeric field).
It's just a list of avaiable recruitment jobs that needs to only show
those before the interview date.
I'm sure this is possible and probably very easy. Can someone show me
a nice simple routine?
Cheers

Yet another utility for doing this, in addition to those mentioned, is
the "pp" program, in the PAR-0.66 distribution.

Interesting!
I've played with perlcc (various linux distros), and have never got it to
work on anything more challenging than a simple "hello world" script. Has
anyone got this to work on any heavy-weight projects, and if so - were
there any tricks to use or gotchas to overcome?
(I've had more success with perl2exe, BTW).

This is a FAQ.
Please read
perldoc -q hide
and
perldoc -q compile

I've recently had good success with pp. This is a free application
based around the PAR module on CPAN. To quote from its documentation:
"DESCRIPTION
pp creates standalone executables from Perl programs, using the
compressed packager provided by the PAR manpage, and dependency
detection heuristics offered by the Module::ScanDeps manpage. Source
files are compressed verbatim without compilation.
You may think of pp as "perlcc that works without hassle". :-)"
It's still under development, and there are a couple of minor bugs to
work out, but for the most part it's ready to go. We have packaged up
fairly weighty PerlTk applications using pp, and all you have to then
distribute is the .exe and a perl dll.
The only changes I needed to make to the source was the addition of a
few extra use statements at the top where the dependancy scanning
routines failed to spot some modules loaded dynamically at run-time, but
I believe the same problems occur with perl2exe and the like.
Of course if you're only doing this to hide source code then none of
these options provides a real solution as with a bit of playing you can
unpack the source, but they make life much easier when distributing
applications to machines without perl installed.
Simon.

ActiveState may not have the latest version. You did not state what
version that is.
I had a problem with WWW::Mecahnize on my w2k box because it used some
module that had some XS code. The problm's been resolved with version
0.37 of WWW::Mechanize. I use it on my W2K box. Perhaps you need to
grab it from CPAN instead of ActionState.

Thanks L D and Michael,
Great! I just got this to work. Yesterday, was my first day really working
with Perl. I'm not doing to bad. lol
Can you suggest a good sniffer program that I can use to see(sniff) what my
browser is sending to sites?
One that works on Win 2K SP2. I know I'll be working with some sites that
require an add_header call or two.
Thanks for your help,
Kelly Greer
