Hopefully the others have addressed your issue. I'd like to comment on 

open FILE, "+< test.cfg" || die "Cannot open file\n" ;

[download]

It's the same thing as 

open FILE, ("+< test.cfg" || die "Cannot open file\n") ;

[download]

You want 

open FILE, "+< test.cfg" or die "Cannot open file\n";

[download]

General rule: If you don't care about the return vakue of the OR, you want or instead of ||.

Better yet, use a lexical file handle, use the 3-arg form of open, and include the cause of the error ($!) in the error message. 

open my $fh, '+<', 'test.cfg" or die "Cannot open file: $!\n";
