Yes, sure, you can achieve it, though it would take you a while to do it.

    Yes I know :-) and I am looking for the way to achieve it. So far I coded like below:
    my @childs; my @allfolders => List of all folders for ( my $i=0; $i<@allFolders; $i+=5 ) { my @sourceFolders = @allFolders[$i..$i+4]; foreach my $folders ( @sourceFolders ) { my $pid = fork(); if ( $pid ) { # parent push(@childs, $pid); } elsif ($pid == 0) { EXECUTe RSYNC HERE.... } else { print "Error: Cannot fork process : $! \n",1); } } foreach ( @childs ) { waitpid($_, 0); } }
    The problem here is that it executes rsync for 5 folders at a time and wait until all of them finishes. BUT, I want to start rsync for 6th folder immediately after 1 of 5 rsync is completed.
