This indeed is more on unix but will be impemented in perl. To make the problem simple:
Let us assume we have two perl scripts running (and in some kind of wait mode). These perl scripts are independednt and do not have any knowledge of each other. Perl script 1 should now establish a communication with perl script 2 to which perl script 2 will do some task and return something to perl script 1.
I will extend the same logic to unix shells later. The question here is... how to make the above possible?

• 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).
