You will get better answers if you provide us with more context around your problem.
After reading your question, my spidey-sense is going off.
Forgive me for making a wild guess, but are you
a Perl novice tasked with maintaining a script originally written by an experienced Perl programmer?
Is the my $file = shift; part of a subroutine?
If so, show us the complete subroutine and where it is being called.
Do you understand how the unwanted "." got there in the first place?
Are you certain it needs to be removed?
Instead of removing it in the subroutine, does it make more sense to ensure it isn't passed to the subroutine in the first place?

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).
