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
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:--  0:00:21 --:--:--     0

ps -ef 查询运行进程
yanggang@barry$ ps -ef | grep curl
yanggang 10992 25473  0 14:11 pts/0    00:00:00 curl -y 30 -Y 1 -m 300 -x 8.8.8.8:808 -o html_baidu http://www.baidu.com
yanggang 18591 11235  0 14:11 pts/1    00:00:00 grep --color=auto curl
ps -ef 查询并过滤进程id:
yanggang@barry$ ps -ef | grep curl
yanggang  9201 25473  0 14:13 pts/0    00:00:00 curl -y 30 -Y 1 -m 300 -x 8.8.8.8:808 -o html_baidu http://www.baidu.com
yanggang 13612 11235  0 14:13 pts/1    00:00:00 grep --color=auto curl
yanggang@barry$ ps -ef | grep curl | grep -v grep | cut -c 15-20
 25473
ps -ef 查询并过滤进程id,并杀死该进程:
yanggang@barry$ ps -ef | grep curl
yanggang 13390 28367  0 14:15 pts/3    00:00:00 curl -y 30 -Y 1 -m 300 -x 8.8.8.8:808 -o html_baidu http://www.baidu.com  (杀死进程前)
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
 28367
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

贴出源码:

# !/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
