That's right... specifically, it depends on what is currently in @ARGV (if there's anything in @ARGV, the contents are treated as file names, and the files are magically opened and read from... if @ARGV is empty, it'll read from STDIN).

If the intent is to read from STDIN, then do so, explicitly, by <STDIN>. If the intent is to process files, generically, either named files or files piped through, then use <>. In the case of the original post, which seems to be (maybe) testing some external code and trying to sandbox it, somewhat, it might just be a good idea to localize @ARGV (that is, to extend the sandbox beyond just STDIN and STDOUT (why isn't he also tieing STDERR, then, though?) to include the command line).

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 or How to display code and escape characters are good places to start.
