The first way that comes to mind offhand would be to do
something like
my @top_lines;
my @other_lines;
while(<FILE>) {
# whatever regex to strip out lines
(/blahblah$/) ? push @top_lines, $_ : push @other_lines, $_;
}
print OUTFILE @top_lines;
print OUTFILE @other_lines;
This would work well provided that the file doesn't get
too big, as the entire thing is going to have to be kept
in memory. But, if it's about 200k as you say, that
should work fine.

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).
