okke The use of moudle worked....but still a curious to know how to transfer data to and from two files in perl via pipes or other mehtod. I am confused on below text book e.g.

use IO::Handle;

pipe(READFROMCHILD.WRITEFROMCHILD);

pipe(READFROMPARENT,WRITETOCHILD);

WRITETOPARENT->autoflush(1);

if ($pid ==fork) {

close(READFROMPARENT);

close(WRITETOPARENT);

print WRITETOCHILD "parent says hi\n";

$data = <READFROMCHILD>;

close READFROMCHILD;

close WRITETOCHILD;

waitpid(-1,0); }

• 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.
