Because you never call the main subroutine.
use strict;
use warnings;
sub main
{
my $path = "\\\\127.0.0.1\\c\$\\bak\\";
$path =~ s/\\$//;
print __FILE__.__LINE__." path $path\n";
return;
}
main();
or even better
use strict;
use warnings;
my $path = <<'EOT';
\\127.0.0.1\c$\bak\
EOT
$path =~ s/\\$//;
printf "%s %s path %s\n", __FILE__, __LINE__, $path;
Unlike C or Java, you don't need a main subroutine; the script just runs in the order it's written, like a shell script. Note as well that I had to escape your $ since " interpolates - you were inserting $\ into your $path assignment. If you'd actually run your subroutine, you would have gotten a warning.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
