in thread splitting the scalar variables in an array

Thanks for the help, I modified the code but that didnt helped either. The scalar value for @dd returned by the code is as follows 1 1 4 Thats because Hostclass-A has 1 host, Hostclass B has 1 and C has 4 hosts. I want scalar(@dd) to be just 6 ( each host should be a separate element in an array )

sub gethosts { foreach $class(@hostclass) { chomp (@hosts_per_hostclass = `/opt/systems/bin/expand-hostclass --hos +ts -r $class`) ; my @dd; push @dd, split "\n", $_ for @hosts_per_hostclass; print scalar(@dd) , "\n"; } }

    Consider this resolved, foreach was printing it 3 times. Final working code is as follows. Thanks to all of you guys fo the pointers.

    sub gethosts { foreach $class(@hostclass) { chomp (@hosts_per_hostclass = `/opt/systems/bin/expand-hostclass --hos +ts -r $class`) ; #print "@hosts_per_hostclass \n"; push @dd, split "\n", $_ for @hosts_per_hostclass; } return @dd; }
