( #3333=superdoc: print w/replies, xml ) Need Help??

The shebang specifies what kind of program needs to interpret the code. Besides Perl, this can be python, bash, sh, etc. Dropping the shebang, makes your shell clueless. What to do with the code?

Presumably, you tried $ perl script instead of $ ./script. In the first example, you just feed perl the script. In the second case, you tell your shell: "Hey, execute this script!". In that case, it would be nice if your shell knew what kind of code it was :)

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.
