Issues reading a simple text file

[tbonell]

Hi,

Thank you in advance for your help.

I am new to PERL, just a couple of days, but reading a lot. I found your site very exciting and informative.

I am trying to read a text file with a key 10 to 120 numbers in a single lime into an array. But I am getting a 500 error and do't know exactly what is the error. I am confused on how to make the code read from my web server (the path).
Perhaps my approach is incorrect!.

my code is as follows:

#!/usr/bin/perl -w
# readtext.pl

use strict;
use CGI ':standard';

$filename = "//mypage.com/key.txt";

open (filename) || die "Couldn't open $filename: $!n";
my @params=<filename>;

print
	   header(),
	   start_html(
	        -title => 'Welcome!',
	        -text  => '#520063'
	        ),
	        h1("the key is: $@params"),
	        end_html();
]

Thanks again

Tony

Add these use statements.

use warnings;
use CGI::Carp qw(fatalsToBrowser);

Remove the -w switch

Lines 7 and 9 have problems which should become apparent after adding the use statements.

Line 18 also has a problem, but lets start with the more important issues.

Ron,

Thank you for your fast response, and comments.

I am still confuse on how to address the path for files under my web server. Could you please recommend any book or web page to read.

I am getting the following error after entering the two lines you suggested. Please see my code and error code as follows:

Error:
open //bcomputingcom.i page.com/cgi-bin/key.txt: No such file or directory at /home/users/web/b1789/ipg.bcomputingc om/cgi-bin/readtext.pl line 12.

#!/usr/bin/perl
# readtext.pl

use strict;
use CGI ':standard';
use warnings;

use CGI::Carp qw(fatalsToBrow ser);

my $inFile = "//bcomputingcom.i page.com/cgi-bin/key.txt";

open(IN, $inFile) or die "open $inFile: $!";
my $line=<IN>;

print
header(),
start_html(
-title => 'Welcome!',
-text => '#520063'
),
h1("the key is: $line"),
end_html();

The open function expects a relative or absolute system path, not a url or unc path. The path you're using is not a system path.
