You're suggesting that one use the HTTPD module to change Unix system
passwords? I must have missed something...

Subject: GDBM: Incompatable between Perl and C??
Message-Id: <605o68$7n4@ns.valinet.com>
Here is a strange problem:
I have a C database utility which uses GDBM files. I am now writing a
simple Perl utility to set keys in the GDBM.
This is what I am doing in Perl:
use GDBM_File;
tie (%DB,GDBM_File,"$myfile",GDBM_WRCREAT,0700)
$val1 = "myval";
$DB{"$val1/test"} = "my value";
So that is basically what I'm doing. I don't untie the db, but that
shouldn't matter. Here's my problem: When I am accessing the GDBM thru
my C program, the above Perl program will produce a value such as:
myval/testsr = my valueO2
Or something like that. It ties on these random strings to the name value
pair.
Any ideas?
Thanks.

C assumes strings are terminated with NULLs, Perl doesn't.

You can exec() and/or fork().
Also note that most implementations of pppd(8) these days handle
by itself so you might not have to start pppd on the back of the
Camel.
http://www.freebsd.org/handbook/handbook173.html convers how to
set up ppp (both via ppp(1) and pppd(8)) in details. Written for
FreeBSD but works for most Un*xen.

You may be wanting the four-argument form of select. Hope this helps!

You need to reconfigure your PERL build script and re-compile the PERl
source using the build script.

On most systems, "telnet" reads commands from the controlling
terminal, not standard input.
In perl, I guess you could use the Net::Telnet module (although that
looks like it requires you to learn about the telnet protocol.) or use
"Comm.pl" (which will open a pseudo terminal for the telnet command to
connect to.)

Message-Id: <604143$qrv$1@trotsky.cig.mot.com>
Hello,
I've been working on a script that parses through selected newsgroups
retrieving Subjects that I later parse and retrieve. However, this all seems
to be done fairly inefficiently.
The basic gist of what my "get subject code" does is this:
open news-server;
set current newsgroup to be the group from my data file;
retrieve the first and last available article numbers;
for all articles since the last time I read articles (or the last 3000,
whichever is a smaller number)
{
foreach line in header
{
if (line =~ /subject/i)
{
save the article number and subject to a file
}
}
}
close output file;
Now, I'm running Perl 5.004 on a Win95 based system at home over a 28.8
connection. This script runs in a DOS window, but seems to take a very long
time to retrieve the desired information from, say, 2000 articles. Netscape
does the same subject retrieval in a fraction of the time.
I have a similar script that, given the news group and article numbers,
retrieves the body of the articles and saves them in incremented files.
I suspect that a large part of my processessing time is taken up in the
"looking for Subject" lines or something along that line. Is there a way to
get the subject lines and article numbers (or some other sort of article
identifyer) in a more efficient/timely manner? Same question except relate it
to the body of the article.
Thanks

I installed perl5 on an NT 4 server. The installation created a key with
the value perllS.dll instead of perl.exe %s %s. Neither seems to work for
me. When I execute the script fron the HTML page, the browser tries to
download the pl. file??
Can someone straghten me out?

Sure it us. Use 'pack'. I've used it to talk RPC, SNMP, NFS

I'm not sure what the Perl to Java compiler is supposed to accomplish.
It seems to me to trade off the good aspects of interpreted (such as
easy to change and run source programs) for all the bad things we
associate with interpreted (big, bulky, slow runtime system).
The only case I can see where the Perl to Java compiler would be useful
is if you wanted to distribute platform- independent code in non-source
format. A lot of people apparently want this.

Subject: Perl, NT, and relational databases
Message-Id: <01bcc725$edcd3fa0$3e0b6682@rob.s.computer>
Hi
I'm currently running a bunch of CGI scripts on NT. The CGI scripts are
written in Visual Basic and are used primarily to store and retrieve
information to and from an Access database. Upon deciding to learn to
write CGI scripts with Perl (so that I wasn't tied to NT with my VB), I
thought I might start my Perl education by rewriting some of my VB CGI in
Perl. I took my first look at some Perl literature today ("Learning Perl"
I think it was called, written by the Perl author) and Perl looks very easy
to learn and use; particularly with the help of CGI.pm. The one thing I
couldn't find info on however was how to interact with relational databases
like Access.
My question: Can Perl be used on NT to store data to and retrieve data from
an Access database with the use of SQL queries (or any other method I
guess)?
Thanks
Rob
PS. Off-topic but... are there any relational database products that can
be used on UNIX?

Subject: Problem of Perl in FrontPage
Message-Id: <874928077.11478@dejanews.com>
I installed MS FrontPage2.0 and perl5 in my computer, and want to make a
test of CGI script in Perl. A test.pl contains just one line: print
"hello, world\n", I define the test.pl the action of a push button in a
form, when I open the HTML file contains the form, and click the button,
nothing happened, and the installed Perl5 have subdirectories like "bin"
and "lib", the FrontPage web have a subdirectory of "cgi-bin". I am
confused, I don't know where to put the perl.exe, or, the perl
intergrater and support libraries? How to make the browser know the place
where Perl lives? How to embed the Perl script in FrontPage2.0 and make
it work? Please give me a hand, e-mail to me. Thanks in advance.

Let me cut you off there. You need a web server to run CGI scripts.
CGI is an acronym for Common Gateway Interface--the mechanism my which
web servers can launch external programs and pass data to them.
Once you have a web server installed (or one on the network which you
can use), the file associate for .pl -> perl.exe needs to be setup. If
you're using ActiveState's Perl for Win32, this happened automatically
when you installed it (assuming you answered yes to that question).
Good Luck,
Jeremy

that's strange - i run CGI scripts without a web server all the time.
remember it's the Common Gateway Interface - not what is on either
side of that interface (remember that CGI.pm allows one to run CGI
scripts without a web server, not to mention various stress-testers
that pretend to be web servers). perhaps you should have said "I need
a web server..." :)

This turns out not to be the case.
$ref = \&nowhere;
print "I've got a reference to an undefined sub!\n" if $ref;

That's the real way to tell whether the sub is defined. Hope this helps!

No replies so far. I think maybe this would work, although I think it is
not really straightforward.
while(s/(.*)<LI>(.*?)<\/LI>/$1/i) {}
$2 will not contain any "<LI>", because $1 slurps up as much as
possible, and neither any "</LI>", because $2 is matched in a non-greedy
manner.

Subject: Regular expression matching
Message-Id: <xm1202hnbvw.fsf@watt.cs.unc.edu>
Hi -
I have a simple matching question. I have a string that
looks like:
*$[value1]$**$[value2]$* ... *$[valueN]$*
where N is known and =5. I find the regular expression
statements, while powerful, still cryptic. I put together
a sample program to pull out one such value (I need to
get all of them), and get a strange error as below. Suggestions
anybody? Thanks.
Dilip
MY SAMPLE PROGRAM
#!/usr/local/bin/perl
$d1 = "\*\$\["; $d2 = "\]\$\*";
$x = "\*\$\[value1\]\$\*\*\$\[value2\]\$\*";
$_ = $x;
print "d1 is \"$d1\" and ";
print "d2 is \"$d2\".";
print "\nSource string is \"$x\".\n";
/$d1(.*)$d2/;
THE OUTPUT
d1 is "*$[" and d2 is "]$*".
Source string is "*$[value1]$**$[value2]$*".
/*$[(.*)]$*/: ?+*{} follows nothing in regexp at try.pl line 11.

Some problems:
1) You must "protect" $d1 and $d2, because '*', '$', '[' and ']'
have special meanings in regular expressions. To avoid lots
of backslashes ($d1 = "\\\*\\\$...") you should use \Q...\E
-> /\Q$d1\E(.*)\Q$d2\E/;
2) Perl is "greedy" which means that it will not work as you expect
it to do. As $d1 matches the beginning of $x and $d2 the very end
of it, the matched pattern will be "value1]$**$[value2". To avoid
this behavior use the non-greedy version (note the '?'):
-> /\Q$d1\E(.*?)\Q$d2\E/;
3) This will only match the first appearance of the desired pattern
(and thus only $1 will be set). To get all of them you might use
a loop like this (note the 'global' option 'g'):
while(/\Q$d1\E(.*?)\Q$d2\E/g) {
print "match is $1\n";
}
Another possible solution is the use of an array:
@a = /\Q$d1\E(.*?)\Q$d2\E/g;
foreach (@a) { print "match is $_\n" }

I think you mean the "bainary search" script. The file is called
"look.pl". It's a Perl4 inheritance, it is included in the "Lib" folder:

Administrivia:
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.
