Well you are describing a "broken" interface (to call it something). You cannot guarantee the copy will be ok. Imagine the other side writes to the file in chunks of 10k every twenty minutes for ...

On the pragmatic side, the idea is simple, check the length of the file every x seconds, copy when it hasn't changed in the last n checks (y = n * x); choose n wisely ;)

Actually on my to_do list is to check File::Monitor; might be useful to you.

While writing this it occurs to me a variation: have the previous check of the size done by a child process, and have the child change the name to *.ok. In the main program just copy the *ok.

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.
