一 杀死指定进程
现知道有一个curl线程正在运行，需要杀死
anggang@barry$ curl -y 30 -Y 1 -m 300 -x 8.8.8.8:808 -o html_baidu http://www.baidu.com

yanggang@barry$ ps -ef | grep curl

yanggang 16946 11235 0 14:15 pts/1 00:00:00 grep --color=auto curl
yanggang@barry$ ps -ef | grep curl | grep -v grep | cut -c 15-20

yanggang@barry$ ps -ef | grep curl | grep -v grep | cut -c 15-20 | xargs kill -9
yanggang@barry$ ps -ef | grep curl
yanggang 13072 11235 0 14:16 pts/1 00:00:00 grep --color=auto curl （杀死进程后，无此进程）
或者：
kill -9 `ps -ef|grep “processname” | grep -v "grep"|awk '{print $2} '`
二 杀死批量进程
for pid in $(ps -ef | grep curl | grep -v grep | cut -c 15-20); do （获取进程id数组，并循环杀死所有进程）
echo $pid
kill -9 $pid
done
# !/bin/sh
for pid in $(ps -ef | grep curl | grep -v grep | cut -c 15-20); do
echo $pid
kill -9 $pid
done
#while [ ! -z $(ps -ef | grep curl | grep -v grep | cut -c 9-15) ]
#do
# ps -ef | grep curl | grep -v grep | cut -c 15-20 | xargs kill -9
# ps -ef | grep curl | grep -v grep | cut -c 9-15 | xargs kill -9
#done
