关掉tomcat 进程
http://stackoverflow.com/questions/15236308/how-do-i-kill-this-tomcat-process-in-terminal

pkill -9 -f tomcat

查找tomcat 进程
ps -ef | grep tomcat => Get all processes with tomcat grep
Once we have process details, we pipe it into the part 2 of the script
awk '{print $2}' | xargs kill -9 => Get the second column [Process id] and kill them with -9 option


通用的做法
ps -ef
will list all your currently running processes

| grep tomcat
will pass the output to grep and look for instances of tomcat. Since the grep is a process itself, it is returned from your command. However, your output shows no processes of Tomcat running.
