At the risk of tooting my own horn, I've put together a page of links to
Perl stuff. It's a work in progress (as is everything on the web), but it
should get you started looking around.

The mother of all perl archives is CPAN:
http://www.perl.com/CPAN/
If you're looking for cgi scripts, you could give
http://www.cgi-resources.com/ a go.

Message-Id: <6kvbdj$bij$1@nnrp1.dejanews.com>
I have successfully processed large files (as large as the 5 Mb and 25 Mb
files you mentioned) under Windows 95 in programs that I've written.
Generally, my applications have processed the files sequentially, using
ReadFile and WriteFile. I have also used file mapping on files of this size.
I have also used the standard C library functions (fopen, fread, fwrite,
fclose) on the same large files.
Now, I have not tried large files with PERL. There might be issues with the
method that PERL uses, or the particular technique it usess.
Have your tried the same thing under Windows NT, just out of curiosity?

John Hart

Succinctly:
1) do $file is like eval `cat $file`, except the former:
1.1: searches @INC.
1.2: bequeaths an *unrelated* lexical scope on the eval'ed code.
2) require $file is like do $file, except the former:
2.1: checks for redundant loading, slipping already loaded files.
2.2: raises an exception on failure to find, compile, or execute $file.
3) require Module is like require "Module.pm", except the former:
3.1: translates each "::" into your system's directory separator.
3.2: primes the parser to disambiguate class Module as an indirect object.
4) use Module is like require Module, except the former:
4.1: loads the module at compile time, not run-time.
4.2: imports symbols and semantics from that package to the current one.

Subject: Saving variable in $ENV{'REMOTE_USER'}
Message-Id: <e$xVr$Yj9GA.284@upnetnews02.moswest.msn.net>
Hello all,
Quick newbie question. When I save a value to the environment variable
"REMOTE_USER" how come that value returns nothing when I call it in a
separate pl script?
I've saved it like this:
sub check_login {
$ENV{'REMOTE_USER'} = $login;
}
Yet, when I use another script to call the environment variable it
returns nothing. I've tried a varied of things... like adding
require "scriptname.pl"
&check_login;
to the calling script, however that does nothing but give a 500 error.
I'm throroughly confused. Perhaps someone could help to shed a little light
on things. Thank you.
Ric

Subject: String to hash utility anyone?
Message-Id: <6kv8c7$h5d$1@malgudi.oar.net>
(Forgive me if this is a repost. My first attempt resulted in an error)
I would like to convert a string to a hash where keys are created based on a
delimiter. Before I write it myself, I was wondering if it has already been
done before.
Basically, I have the following strings
"dir1/sdir1/sdir11/file11.txt"
"dir1/sdir2/file2.txt"
"dir1/sdir3/sdir33/sdir333/file333.txt"
and I would like to place them in a hash based on the delimiter "/":
$hash{dir1}{sdir1}{sdir11}=file11.txt
$hash{dir1}{sdir2}=file11.txt
$hash{dir1}{sdir3}{sdir33}{sdir333}=file333.txt

Subject: Suggestions?
Message-Id: <6kvahg$9g6$1@nnrp1.dejanews.com>
I'm interested in building a cgi script that searches a simple flat file
database. The cgi doesn't need to write to or modify the file in any way. I
just want to query for matches in certain fields and return the matching
records as formatted lists in a frame. To be exact, I want to give the viewer
an opportunity to look for groups that can provide services for them. I'd like
to keep the number of fields they can search for to three (any or all fields).
I'd also like to embed HTML info in the database fields so formatting is
easier to keep consistent. My questions are these:
1. I have absolutely no experience with SQL or any kind of query language for
databases. Can I use Berkeley DB to hold the records? Is this a good database
application for keeping this simple database considering I'll be learning it
from scratch? The number of records will probably never exceed 2000.
2. Has anyone had experience with Sprite? I've read some about this and
although I've never used it, it seems pretty easy.
3. Does anyone have experience embedding HTML in database records? Or, is
there an elegant solution to automatically providing HTML code in returned
queries of databases other than embedding HTML in the records?
I am just beginning to learn Perl and have a *long* way to go. I have the
basic books (Learning Perl and Programming Perl) and I realize from the outset
that it'll be slow going for a while till I get my bearings. Lastly, are
there any really (overly?) documented scripts that I can step through
visually to get an idea of script flow and style. Whew! This is going to
take some time.
Thanks in advance.
Sean

use Net::FTP, if you have the standard win32 port of perl, you already have it
installed. The documentation explains it's functions pretty clearly.

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:

to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your

To submit articles to comp.lang.perl.announce, send your article to

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
