RE: Learning Perl
Try purchasing a Book. O'Reilly would be good. After that you can go to : http://cgi.resourceindex.com and download some free scripts and try them. You may try some tutorials on the web, but it's very important (at least in my experience) that you first begin with the hard introduction. After that you can explore the sweetness of this languaje. -rm- - Original Message - From: Ohad Ohad <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, April 02, 2003 1:31 AM Subject: Learning Perl > hey, > > I guess this question came up several time already so a link will be fine. > > What is the best way to learn Perl for someone with very basic programming > skills. > > 10x > > Ohad. > > _ > Protect your PC - get McAfee.com VirusScan Online > http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963 > > > -- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: javascript and perl dbi
Hope I'm not missing the context of the question :-o
--
You can include Javascript as any HTML code
print "\n";
print " var SealoffSource = true\; /* Deshabilitar Click
Derecho. */\n";
print " function click() {if (event.button==2)
{alert(\'Hardware: Mouse - Error. Please reboot.\')}}\n";
print "document.onmousedown=click\;\n";
print "\n";
Just be careful to not miss a backslash.
Or, as Dan said, use Here Documents.
I've found some details here:

If that finction won't do what you need then don't use it.
See search.cpan.org and look for CGI.pm there's lots of info there.
You could use a 'here' doc.
print <
javascript...
...
HTML
Just watch out for your quotes and backslash them if need be.

Password protected script.
Hello again. I'm trying to write a script for uploading some files, but I want it to be password protected, giving this way restricted acces to some users. I don't want to set a password for the directory where the script lies on, I'd prefeer the protection beeing inside the script.

Help with script , error 500
Hello everyone.
I have a problem that has me blinded. I'm working on a script for finding
the 3 greatest numbers on a group of data stored in a TXT file.
I keep getting the same 500 error.
I used some pieces of code from others scripts I made that work correctly,
but this is my headache. Maybe is a syntax error, but I am so tired of
looking for it. So I ask you to help me tracking the mistake in this script.
Thank you to all of you for taking the time
imagenes.dat is stored in the same directory that the script.
---CODE
#!/usr/bin/perl
$file_url = "http://www.sistemedic.com/votar";;
$bd = imagenes.dat;
open (DATOS, "$bd") || die "Error: no se puede abrir el archivo";
while () {
$reg = $_;
($file, $vot_tot, $sum_vot, $coment, $prop) = split(/\|/,$reg);
$prom = $sum_vot / $vot_tot;
$ltop{$file} = $prom;
}
close (DATOS);
# @proms = values (%ltop);
@images = keys (%ltop);
$ind=0;
$max_1=0;
$max_2=0;
$max_3=0;
foreach $comp (values(%ltop)){
if ($comp > $max_1) {
$max_1 = $comp;
$ind_1 = $ind;
}elsif ($comp > $max_2){
$max_2 = $comp;
$ind_2 = $ind;
}elsif ($comp > $max_3){
$max_3 = $comp;
$ind_3 = $ind;
}else{
$ind = $ind;
}
$ind ++;
}
$prom_1 = sprintf '%3.2f', $max_1;
$prom_2 = sprintf '%3.2f', $max_2;
$prom_3 = sprintf '%3.2f', $max_3;
print "content-type: text/html \n\n";
print "\n\n";
print "Top 3\n";
print "\n";
print "\n";
print " \n";
print "\n";
print " $prom_1\n";
print "\n";
print " $prom_2\n";
print "\n";
print " $prom_3\n";
print " \n";

As you can see I have made some weird arrangements, trying to find out the

Use of SSI
I'm trying to use a Script for showing who's online on my site. I have been using it on the main page, but I want it to look for somebody who could have get in the site trhough anoter page. The matter is I need to use SSI for calling the script. To look on the entire site I need to use SSI on every pages. This means change from .HTML to .SHTML (I need to do that with my host). What are the inconveniences of having all my pages as .SHTML??? I know the server will make a scan (or something like that ) on every .SHTML page, making them a little slower to load. Can this be annoying for the surfer??? How does the size of the .HTML file affects???. --- It may sound off topic, but at last it's for keep using PERL the best way on my site .. ;-) Thanks everybody. -rm- -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Newbie question about modules
Hello all. I've reading some messges relating to the use of modules. How can I know what modules are installed in the server??? I have my site hosted on a Server far away from here. And it provides me Perl with "the most commonly used modules". Being that I'm not an expert on Perl I don't know what are the most commonly used modules. I have no Telnet access, but only FTP, that has been quite enough for me. The obvious answer to my question is to "ask my hosting provider" this info, but I think I'd prefeer a little more complex solution, if it exists. Is there a way I can find out this without asking my service provider?? Thanks to all of you. -rm- -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Formatting Variables.
Hello boys and girls. Is there a way to give format to a Variable. I mean, if I don't want to get printed 3.1415926535 (Or any irrational number) but something like 3.14, is there a way to use format?? Or I need to make some string treating (more lines)?? Thank you everyone. -rm- -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Reading Plain Text File - help
Thank you very much guys.
Rob, sorry but it didn't work
open (DATOS, "$bd") || die "Error: no se puede abrir el
archivo";
while ($registro=) {}
($file, $vot_tot, $ult_vot, $sum_vot) = split(/:/,$registro);
$lineas = $.;
close (DATOS);
I had a good feeling about it but wasn't enough.
David. It made it:
open (DATOS, "$bd") || die "Error: no se puede abrir el
archivo";
while ($registro=) {
$registro = $_;
}
($file, $vot_tot, $ult_vot, $sum_vot) = split(/:/,$registro);
$lineas = $.;
close (DATOS);
Altough I'd like to avoid $registro = $_; in order to use less lines.
Anyway thank you.

You are working too hard at it Just replace $registro = with
$registro = $_; and it will work for you. What you are doing are double
reads of the file. What while ( ) is reading one record into $_ and
the other line is reading into $registro. The file you are working with
probably has an odd number of lines. So just do:
while (){
$registro = $_;
}
Wags ;)

Trying PERL in windows
Hello everybody. Does any of you know if there's a way to try Perl scripts on windows? And I'm not meaning using a Perl interpreter for W32. I mean, I'm running a website hosted on a remote server (I have FTP access only) that's running Apache on Linux. And I'm using some Perl scripts from the web. But now I want to write my own ones. I can't be connected to the web all the day, so it would be very useful to have, say a server emmulator running perl on my windows machine. Just for trying the scripts. Is there some sort of software doing that? Or I am just dreaming ? -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
