Two new features has been incorporated into 5.8.0rc2 which allow for the creation and handling of temporary files in a secure manner. The first is the incorporation of means to create anonymous temporary files, similar to the unlinking of open files described above, without the need to make use of external modules via:

open( $fh, '+>', undef ) || die $!;
[download]

Where the undefined value is a literal undef statement, rather than an undefined variable. It should also be noted that the File::Temp module has now too been incorporated into the core distribution.

Another feature which allows for temporary file-type handling within code is that which allows for file handles to be opened into a memory space, via a scalar reference - For example:

open( $fh, '>', \$variable ) || die $!;
[download]

• 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.
