Borrowing tachyon's example, and leaving out the rle function definition for brevity, many examples of which can be borrowed and modified from here (This solution is probably better if you were going to look for many letter lists as opposed to just one):
@dict = qw (foo oof fff bar baz); $letters = 'ofo'; my %dict; push @{$dict{rle(sort split '',$_)}}, $_ for @dict; $words = $dict{rle(sort split '',$letters)} || []; print "$_\n" for @$words;
Update: Realized you don't actually need the rle function:
my %dict; push @{$dict{join('', sort split '',$_)}}, $_ for @dict; $words = $dict{join('', sort split '',$letters)} || []; print "$_\n" for @$words;

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
