USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND

通过cut  获取进程号pid

再通过xargs kill

[root@hadoop2 ~]# ps -aux | grep chk | grep -v grep | cut -c 10-16 | xargs kill -9

usage: kill [ -s signal | -p ] [ -a ] pid ...
kill -l [ signal ]
[root@hadoop2 ~]#

业务写法

 ps -aux | grep chk | grep -v grep | grep Dec08 | cut -c 10-16 | xargs kill -9
