Thanks for showing me that splice trick. I don't think it
took anything off the benchmark times, but it removed the
temp array I was using. When I do
tailz t.dat 5 | wc -l
I get 5. (Just lucky).
perl -le'print "a"x5000 for 1..10' > t.dat
does give bad results
The code still depends on you knowing your
max line length beforehand, but I think this is true
for more logs and text files.
I'm happy now, at least I figured out what Merlyn meant
when he said there was a faster method than Tie::File or
File::ReadBackwards.

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).
