Hello glendeni,
Yes, /\s/ does match a newline character:
13:41 >perl -wE "say qq[Matched >$1<] if qq[abc2345] =~ /([0-9]+)\s/;
13:41 >perl -wE "say qq[Matched >$1<] if qq[abc2345 ] =~ /([0-9]+)\s/;
Matched >2345<
13:42 >perl -wE "say qq[Matched >$1<] if qq[abc2345\n] =~ /([0-9]+)\s/
+;
Matched >2345<
13:42 >perl -v
This is perl 5, version 26, subversion 0 (v5.26.0) built for MSWin32-x
+64-multi-thread-ld
For the meaning of \s in a regex, see “Whitespace” in perlrecharclass#Backslash-sequences.
Hope that helps,

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).

or How to display code and escape characters
are good places to start.
