im something of a fascist unix admin when it comes to consistency of
where
programs should be. you create more complexity by adding a 'wrapper' and
make it even less portable. i see people do this all the time and it
makes
no sense to me. if you are not the admin or if you are i would highly
recommend symbolic links to /usr/local... or wherever your perl is
across
all the systems. consistency and simplicity are your friends. if there
were
a function called by shebang that would look for perl, that would be
elegant
but in lieu of that you may be better off with the consistent
location/links.

Look at the 'x' command line option for perl.
Basically it's be something like:
#!nonperlprogram
... do some stuff that isn't perl ...
... including calling perl with the -x flag and the name of ...
... this script ...
#!perl <flags>
... do some stuff that _is_ perl ...
__END__
Hope this helps!

Of course, /usr/local/bin/perl should be a symlink pointing to the real
perl on nearly any Unix-like system.

There's something about this in the perlrun manpage. Hope this helps!

I insert this code into my test.shtml file

Yes, it's a stupid NT sever, but I don't have any control over that. Am I
just making a stupid mistake or is there something I can try to run this
script? The script will run fine when it's run by itself in the browser.
Thanks.

SSIs need to be set up in the server. The docs, FAQs, and newsgroups about

=====
- A line in the body of a post is considered to be original if it
does *not* match the regular expression /^\s{0,3}(?:>|:|\S+>|\+\+)/.
- All text after the last cut line (/^-- $/) in the body is
considered to be the author's signature.
- The scanner prefers the Reply-To: header over the From: header
in determining the "real" e-mail address and name.
- Original Content Rating (OCR) is the ratio of the original content
volume to the total body volume.

That doesn't add anything over storing the passwords in the source
of the program - you can as easily make the script only readable
by whoever runs the script.
In fact, this is exactly why there are file permissions on Unix.
I would do the following:
- Run the cgi programs under a user-id of which only "trusted"
people have the password. ("trusted" people: people who have
nothing to gain by reading the database password, for instance,
because they already have it).
- Make your script readonly for that user.
- Create a dedicated user in the database, to be used from the
script. (You might want to give the user limited permissions).
Use the user-id and password of that user in the script.

Just because 32 bits was choosen to fit a certain hardware size doesn't

It isn't.

You forgot to allow mixed case. You forgot to allow quotes.
Why does everyone want to parse HTML with regexen? It's much simpler
to do (and much more likely to be correct) with Gisle's parser.

Based on your last few posts, it sounds like you have a lot of regex
handling to do in your work. For about $30.00 (US) you can purchase
Jeffrey Friedl's "Mastering Regular Expressions". Honestly, this is
an enjoyable read ... not dry at all, and in just a week or two, you'll
be totally independent in working on your regexes ... it will save
you *lots* of time ... honestly. You can get it from the publisher
(O'Reilly and Assoc www.ora.com), Barnes and Noble, Amazon, etc.
Hope you believe me ...

Administrivia:
Special notice: in a few days, the new group comp.lang.perl.moderated
should be formed. I would rather not support two different groups, and I
know of no other plans to create a digested moderated group. This leaves
me with two options: 1) keep on with this group 2) change to the
moderated one.
If you have opinions on this, send them to
perl-users-request@ruby.oce.orst.edu.
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.
