Nice example! I prefer autoflush because the intent is much clearer than messing with the $| global variable.

As an aside, it's a shame Perl was originally released with so many evil global variables because by the time lexical file handles made it into Perl 5.6 a host of unfortunate idioms were in common use, such as:

select((select(FH), $|=1)[0]);

Of course, such old coding horrors like this can be expressed more clearly nowadays with a lexical file handle (see also):

use IO::Handle; # update: not needed for Perl 5.14+ # ... $fh->autoflush();

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.
