( #3333=superdoc: print w/replies, xml ) Need Help??
Alternately to what JavaFan said, you could also do this:
use File::Slurp; chdir "/tmp/test"; my @files = grep { -f and /^\d{8}\.\d{6}\.host\d\.\d{1,6}$/ } read_dir + "."; print "Got ". scalar(@files) . "\n";
Of course, if the script is going to do anything else, and needs to keep track of the original working directory, use Cwd to find out where you are before you do chdir.

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.
