[root@katello ~]# kill -9 `ps -aef | grep katello | grep -v grep | awk '{print $2}'`
kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]
[root@katello ~]# kill -9 `ps -aef | grep delayed_job | grep -v grep | awk '{print $2}'`
kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]

Expected results:
kill should return nothing instead of an error bombing out because it found no PID to kill or the kills in the document are unnessesary
