I am newbie in Perl programming and currently trying to use Net::OpenSSH module in my code, my new code as below which the task is to run multiple command in remote server, Code as below:: 

foreach $s (@servers) {
my $ssh = Net::OpenSSH->new("$username\@$s", timeout=>30);
$ssh->error and die "Unable to connect: " . $ssh->error;
print "Connected to $s\n";

my $fh = $ssh->capture("df -k /home/ | tail -1") or die "Unable to run
+ command\n";
my @df_arr = split(/\s+/, $fh);
print "$s:  Disk space /home/ = $df_arr[3] \n";

my $fh1 = $ssh->capture("svmon -G -O unit=GB | grep memory") or die "U
+nable to run command\n";
my @sv_arr = split(/\s+/, $fh1);
print "$s:  Free memory = $sv_arr[3] \n\n";

close $fh;
undef $ssh;
}

This code is not so nice since I plan to simplify and reduce a line as many as possible. Does there are any techniques or methods that I can use to simplify this code?
