if the file isn't big, read it all in an array, then when you find your match, save your location, and retrieve it directly from the array..
Update:Here it is, completely untested for bugs:
# assuming the file is already opened and has a <IN> filehandle
my @temp;
# and assuming that you won't match before the first 5 lines..
while (my $line = <IN>) {
push @temp, $line;
shift @temp if (scalar @temp > 5);
if ($line =~ /foo/) {
# we've got a match.
print $temp[0];
}
}
Update 2: This looks like davorg's more elegant solution.
He who asks will be a fool for five minutes, but he who doesn't ask will remain a fool for life.

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).
