Re: CGI Command Line

[barrachois]

Use the CGI.pm module and follow the directions in its debugging documentation.

For example, if your script is in the file color.cgi

#!/usr/bin/perl -T
use strict;
use warnings;
use CGI qw(:standard);
use CGI::Carp qw(fatalsToBrowser);
print "Content-type: text/plain\n\n";
my $color=param('color');
print "Your chosen color is $color.\n";

then from the command line you can type

 ./color.cgi color=red

to see it run as it would from a URL like color.cgi?color=red

I didn't realize that it was that simple. That's very useful Thanks a lot! Joe

I also like using Data::Dumper when debugging my CGI scripts.

#!/usr/bin/perl -T
use strict;
use warnings;
use CGI qw(:standard);
use CGI::Carp qw(fatalsToBrowser);
use Data::Dumper;
print "Content-type: text/plain\n\n";
my $color=param('color');
print Dumper($color);
exit;
print "Your chosen color is $color.\n";

# ./color.cgi color=red
Content-type: text/plain

$VAR1 = 'red';

It's useful when the script is big and all you want is to check a variable in a middle of it.

Ooh! Very nice! That's soo much easier that writing my own code to do that type of debugging. Thanks for the tip! Joe
