Hi there

This is an embarassingly easy question I'm sure, but I simply dont know why my wee script isnt working properly.

I have a text file that looks like this: 
1.2.56.3
3.55.7.3
etc

[download]
and I want to split the contents of each line on the period so that for: 
1.2.56.3

[download]
I get 
$nums[0] = 1, 
$nums[1] = 2  
$nums[3] = 56
etc

[download]
Could anyone please point out whatever silly error is in my script? At the moment $nums[0] when printed contains the enire contents of the line e.g. 1.2.56.3 and all the others are (obviously) empty 
#!/usr/bin/env perl

use strict;

my $file = shift;

open(FILE, $file) || die "Unable to open $file for reading: $!\n";

while(<FILE>)
{
    my @sf = split;

    #print "@sf\n"; print test

    my @nums = split(/\\./, $sf[0]);

    #print "@nums\n";

    print "$nums[0]\n";

}

All help much appreciated!
