Hi gurus


Is there a way to run multiple SUB progrmans at the same time in one PERL script ? Or do I need to make multiple PERL scripts ?

So let's asume that I have program:

----------EXSAMPLE---------------

#!/usr/bin/perl -w

use Net::FTP;

&FTP1;
&FTP2;
&FTP3;

----------END---------------


I need to run those sub scripts at the same time and I don't want to PERL ends with the firs FTP before moving to second one.


Thanks for any advise


- Jussi

U can try threading:

use Thread;
$th1=Thread->new(\&FTP1);
$th2=Thread->new(\&FTP2);
$th3=Thread->new(\&FTP3);
$retval=$th1->join();
$retval=$th2->join();
$retval=$th3->join();

Using this module, you can write a loop like a "foreach" loop. But the good thing is that all the iterations of the loop happen parallely. You can also specify the parallelism you need.
