Added exactly one line to your code and got results. Here's the new code: 

#!/usr/bin/perl -w 
use strict;
use warnings;
sub main
{
    my $path = "\\\\127.0.0.1\\c$\\bak\\";
    $path =~ s/\\$//;
    print __FILE__.__LINE__." path $path\n";
    return;

}

main();

and here are the results: 
$ ./hackslash.pl
Use of uninitialized value $\ in concatenation (.) or string at ./hack
+slash.pl line 6.
./hackslash.pl8 path \\127.0.0.1\ak

What I think you really wanted was to add a backslash before the $ since normally that would have been interpoloated resulting in : 
# note the backslash in front of the dollar sign
my $path = "\\\\127.0.0.1\\c\$\\bak\\";

giving you: 
$ ./hackslash.pl 
./hackslash.pl8 path \\127.0.0.1\c$\bak

Creating a sub without calling it will act as a NOOP.
