Can you do:
print scalar(`command`);
That will guarantee to be "in order" with your other perl code. Set
autoflush if needed. If you need a return code, you'll need to use
piped opens (and closes).

Agreed. Also it might be worthing looking on Dejanews in the group
comp.database.ms-access for reasons that .MDB are unlikely to be
supported on any other than a Microsoft platform.

Similar in function, but more lightwieght, and much less full
featured. Mine only handles basic ACL and group files (no DBM
or SQL), and only requires core modules for support. Mine is
also not designed to run as CGI out of the box, although it
could be used in that type of implementation.
Its a smaller wheel.

Close. Perl starts only one process, and waits for that one to complete.
But if that one is a shell which starts more than one (which I think is
happening in your case), _it_ waits for them all, and perl waits for it.

See what perlfaq8 says about starting a process in the background. Good
luck with it!

When you're having trouble with a CGI program in Perl, you should first
look at the please-don't-be-offended-by-the-name Idiot's Guide to solving
such problems. It's available on CPAN.

You should really ask in comp.database.ms-access or check the Microsoft
web site for information on this - you either have a missing or an
incompatible .dll (which eludes me right now.)

I would be interested in learning how the documentation project of Perl
started out. When did someone and who did start to write the first .pod
files (if it was in fact ONLY you, do you think several authors could
have worked on it together)? If you could redo everything you did
concerning your involvement with Perl, what would you do differently
today ? How would you structure a documentation this size ? Have you
honestly seen people working together on one consistent piece of
documentation - online - long distance ? Or was it in fact basically one
person who did 98% of all the work ? If yes, could there have been a
team ? I mean would it work in reality ? If not, why not ?
Do you think that it is a good idea to divide the documentation writing
from the code writing between the author of the code and (an)other
author/s for the documentation.
Is in general the author of a large software project the only person who
really can document it (being the master guru) and is it just lucky
coincidence if the author finds other minimaster gurus who dedicate
everything they got to write a good documentation (and bad luck
if he doesn't find such persons)?
How often do you think authors don't want to write documentation because
they are burned out from code writing, and how often because they want
to keep more control and power over it ? *
birgitt
* I am asking this only because as an outsider to the IT world, I had
the opportunity to be an intern in the IT department of my families
insurance brokerage company, in which a large application was developed
in the eighties over a period of four years by three people. The package
was successfully used by our company and sold several times in the
industry to other brokers and did serve its purpose very well. As it
turns out today the package can't be used more than three to four more
years longer before something similar in function has to be completely
rewritten. This package contained an huge amount of "intelligence"
of this particular "industry". But the package is so poorly documented,
if at all, that only two persons (and each of them only half of the
package) in the company could rescue the company if there would be a
major hardware crash, nor can this "knowledge" be taken over into the
package which has to be developed in the near future. The company can't
afford a down-time of their system of more than five days. Seeing the
livelyhood of a company and with it some 700 people, which exists over
125 years to be dependent on ONE person, I was inclined to ask the (new
incoming) deputy chief of the IT department what he thinks about this
situation. His flat answer: "That is (in German: "Herrschaftswissen")
Knowledge of the people in power".
I just wondered what the heck my brothers, cousins, fathers and uncles
were thinking when they allowed that to happen. Who is in power of whom
and what ? Why is it that documentation is very often neglected ? Is it
lack of money, lack of the detailed insider knowledge of a software
package by people other than the developers themselves or is it "on
purpose" ? - Just shaking my head in disbelieve - . And I hear stories
similar to that one from other companies...

If you want to know what sendmail can do, the docs, FAQs, and newsgroups
about sendmail should be able to help. If you want to know about what
modules are available to use with Perl, check the Module List on CPAN.

Subject: ENV Question
Message-Id: <7jp71u$s59$1@nnrp1.deja.com>
I'm trying to set some ENV variables in a script. What am I doing
wrong:
#!/home/orca/rfadba/perl5/bin/perl
BEGIN {
$ENV{LD_LIBRARY_PATH}="/usr/openwin/lib:/home/orca/rfadba/oracle7.3.4/lib";
$ENV{ORACLE_HOME}="/home/orca/rfadba/oracle7.3.4";
}
eval 'use Oraperl; 1' || print "error with Oraperl $@ $]\n";
The above gives all sorts of errors about not being able to find
"libclntcsh". Setting the environment BEFORE I call the script works
fine.
Any light anyone could shed would be GREATLY appreciated. Thanks!

Someone could probably figure this out; but in the mean time,
why don't you try using MLDBM, with something like Data::Dumper;
that will do what you want to do. May as well leverage all the
work that people have already done, solving common needs like this.
Please perldoc -f dbmopen.
Also, passing things by typeglob is considered passe.

Subject: newbie question: Perl for sorting/generating html
Message-Id: <376037F6.50C1EDAB@msiprod.com>
Hello,
Newbie question here. I read through the faqs and think that learning
Perl will be the best way to do the following (but would like some
reassurance/suggestions):
Say I have a directory of html pages with similar content that is ever
growing. (Typically, the page consists of a jpg at the top, a headline,
body text, another pic at the bottom, plus the usual navigation stuff.)
I want to have a page generated on the fly that is like a
thumbnail/browser thing for the directory. My thinking is to write a
script that will look at each html page in the directory then, pull out
the thumbnail jpg, one or two heading lines, possibly a couple lines of
text from the article and generate the thumbnail page. I'm thinking
this is similar to the "photo gallery" type of things that I've seen
Perl do, but just more involved.
Looking for the best way to do this, somebody suggested Perl. (I'm no
programmer, but did o.k. in my BASIC class years ago...)
Any info/suggestions appreciated.
Regards,
Lee Schwabe

I believe that you can right click on the icon for the actual bat file
and change the properties without starting it - it will create another

I think the best approach to this kind of problem is to deal not with
one line at a time (which requires managing several flags to tell you
where you are), but with one 'record' at a time, where in this case the
record separator is the "\n[" that demarcates each of your 'sections'.
The following code grabs a 'section' at a time, then processes it all
out of $_. No repetitive code, no flags, no fuss, no muss, no bother.
#!/usr/local/bin/perl -w
use strict;
use vars qw($line1 $line2 $line3);
{ local $/ = "\n[";
while (<DATA>) {
chomp; # Strip section-beginning marker
s/^\s*(#.*)?\n//gm; # Strip blank lines and comment lines
s/^\s+//gm; # Trim leading space on each line
s/\s+$//gm; # Trim trailing space on each line
next unless length; # Just getting started
s/(.+)]\n// or die "$_: No section name after '['.\n";
my $secname = lc $1; # Save the section name
print "=================\n$secname\n";
# Grab the next three lines
s/(.+)\n(.+)\n(.+)\n// or die "$_: No initial three lines.\n";
($line1, $line2, $line3) = ($1, $2, $3);
print "$line1\nline2\n$line3\n";
# Process the remaining lines of the section
print;
}

That avoids the issue of using NT at all.
One can create a quite capable Unix/POSIX environment on NT using
commercial tools such as the MKS Toolkit, or free tools such as the Perl
Power Tools <URL:http://language.perl.com/ppt/>. Practically every
command that is not OS-specific is available.

Subject: Retrieving email
Message-Id: <929053001.21407@www.remarq.com>
I am writing a perl script to retrieve email and do specific
things with it according to subject. I am current using
Mail:POP3Client module and all is fine except when I go to
use the Retrieve function. It returns both the head and body
as expected, but it looses the formating of the message.
Everything is then dumped into one line.. Some direction is
certainly apprectiated.

When perl does the I/O for you (effectively, calling sysread and syswrite
itself) it takes care of the things that can go wrong. For example,
sysread calls read(2), and that manpage (which see) says that if an
interrupt occurs while trying to read, the read may return with no data.
If there's an error like that Perl's sysread returns undef, and $! will be
set to an appropriate value. See the Errno module to find out what they
look like on your system.
Hope this helps!

Yes; and
my_truly_random_function() ? "19$year" : 1900+$year;
is equivalent to Schroedinger's famous thought-experiment.

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.
