Just for interest, here's the same approach in Perl 6:
use v6;
my regex fields { \" <( .*? )> \" | <-[,"]>* }
my $input = open 'input.csv', :r;
my $output = open 'output.tff', :w;
for $input.lines {
next unless /<fields>* % ','/;
$output.print: @<fields>.join(chr 31) ~ chr 30;
}
$output.close;
That's not the shortest way to do it in Perl 6, but it's closest to the Perl 5 example above.
A shorter and more Perl6-ish version might be:
my regex fields { \" <( .*? )> \" | <-[,"]>* }
lines open 'input.csv'
==> map({@<fields>.join(chr 31) ~ chr 30 if /<fields>* % ','/})
==> spurt('output.tff');

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).
