[root@openvas ~]# ps -ef |grep httpd |sort -r -k 8 |tail -5
apache 19785 4416 0 16:29 ? 00:00:00 /usr/sbin/httpd
apache 19784 4416 0 16:29 ? 00:00:00 /usr/sbin/httpd
apache 19778 4416 0 16:29 ? 00:00:00 /usr/sbin/httpd
apache 19762 4416 0 16:28 ? 00:00:00 /usr/sbin/httpd
root 21078 11822 0 23:34 pts/0 00:00:00 grep httpd
