or, if you don't know what the words are ahead of time:
#!/usr/bin/perl -w

my @approved = qw( foo bar);

qr/$_/is; ## available in perl 6, not really needed
} @approved;
print "The approved list\n", join "\n", @approved;
my $merex = join ' && ', map "/$_/", @approved;
print "merex \n$merex\n\n";
if(@ARGV)

while(<DATA>)

}
else

while(<DATA>)
{
my $toprint = 0;
for my $r(@approved)
{
$toprint++ if m/$r/;
}
print if $toprint == scalar @approved;
}
}
__DATA__

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
