Hi all, I have a problem in coding. I have the following file (each row is divided by ; in 5 fields): 
.0000000001;2;1;.5;.2
.5;2;1;.5;.5
0.3;1.5;.5;.5;.2
1;1;.7;1;1
.4;1;.4;1;.5

I want to sort the rows in descending order according to their first field, so I typed the following script: 
#!/usr/bin/perl

use strict;
use diagnostics;
use warnings;

my $fh;
my @lines = ();
my @sortedlines = ();

open($fh, "<", "filename") or die "I cannot open the file: $!\n";
chomp(@lines = <$fh>);

@sortedlines = sort { $b =~ /(^\d*\.*\d+);/ <=> $a =~ /(^\d*\.*\d+);/ 
+} @lines;
print "SORTED LINES = @sortedlines\n";

but it doesn't work!
Where's the problem?
Thanks in advance,
Saverio
