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

I guess it all comes down to whether your goal in calling system is to provide shell-like capacities, or simply to execute foreign code. I stand by my statement that there are very few instances where the multiple-argument form is a hinderance: it is only a hinderance where you need to interact with the shell directly.

Perhaps your direct experience with system is largely in that category; mine, however, is not -- most times, I see calls to system that are simply execution of foreign code, and require no shell capabilities in the first place.

As for the response to the shell escaping/quoting, it's technically correct if pedantic. The point is, one bypasses the issue when using the multi-arg form -- how isn't entirely important, sorry if the over-simplification confused or annoyed anyone.

Because there are clearly times when the single-argument forms are appropriate, I would not (as I have said before) suggest that this be a high-severity warning. However, it would be a good thing to tickle at a lower severity, from the point of view of "are you sure you know what you're doing, here?"

We've both made our points, and I certainly respect your point of view. I think we'll just have to agree to disagreesort-of agree ;-) on this one.

Title:
Use:  <p> text here (a paragraph) </p>

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.
