}
__DATA__
foo bar

gives output:

foo no match
bar no match
baz no match

hth!

Update re jeroenes's points below:
1. I used /s to make '.' match any character, in case fsn's *real* strings weren't all in one line.
2. Yes, or even print grep /(?=.*foo)(?=.*bar)/, <DATA> ; , but I wanted to print the failed matches too. Perhaps print map{ chomp; /(?=.*foo)(?=.*bar)/?"$_ yes \n":"$_ no \n"} <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).

are good places to start.
