Reverse the output using for loop
Good morning!!

Im trying to ge tthe output in this for loop to be reversed.

[code]
#!/usr/bin/perl
$i = 1;
for($i != 0 ; $i < 11 ; $i++){
print "$i\n";
}


Ive tried changing the i++ to i--, but it makes the outputted numbers different also.

Thanks

TSMOKE(1)							     SmokePing								 TSMOKE(1)

NAME

       tSmoke - Commandline tool for sending SmokePing information

SYNOPSIS

       tSmoke [ --testmail | --morning | --weekly | --version | --help | --man]

	Options:

	--man	   Show the manpage
	--help	   Help :-)
	--version  Show SmokePing Version

	--detail   How much detail to send in weekly report (i.e. '--detail=1')
	--quiet    Do not print welcome

DESCRIPTION

       The tSmoke tool is a commandline tool which interfaces with the SmokePing system.  Its main function is to send a message indicating the
       current status of the systems being monitored by Smokeping or an HTML mail file containing the status over the past day, past week and past
       month including an overview.

       Typical crontab used to invoke this are

	# Quick morning alert to see what's down
	0 6 * * * /usr/local/smokeping/bin/tSmoke.pl --q --to=mobilephone@att.net.invalid --morning
	# Weekly report on the percent availability of network systems with no detail
	0 8 * * * /usr/local/smokeping/bin/tSmoke.pl --q --to=mailbox@company.com.invalid --weekly --detail=0

SETUP

       When installing tSmoke, some variables must be adjusted to fit your local system.

       We need to use the following libraries:

       Smokeping
       RRDTool Perl bindings
       Getopt::Long

       Set up your libraries:

	use lib "/usr/local/smokeping/lib";
	use lib "/usr/local/rrdtool-1.0.39/lib/perl";

       Point to your Smokeping config file

	my $cfgfile = "/usr/local/smokeping/etc/config";

       Modify the Smokeping config file to include a path for tmail in the General section:

	tmail = /usr/local/smokeping/etc/tmail
