Linux kill 杀死指定进程

一  杀死指定进程

现知道有一个php线程正在运行，需要杀死

root 26278 1 0 2015 ? 00:00:31 /usr/local/php/bin/php /var/www/html/redis/daemon/daemon_register.php
root 26280 1 0 2015 ? 00:00:34 /usr/local/php/bin/php /var/www/html/redis/daemon/daemon_register.php

ps -ef 查询运行进程

leo@localhost$ ps -ef | grep php

root 26278 1 0 2015 ? 00:00:31 /usr/local/php/bin/php /var/www/html/redis/daemon/daemon_register.php
root 26280 1 0 2015 ? 00:00:34 /usr/local/php/bin/php /var/www/html/redis/daemon/daemon_register.php

ps -ef 查询并过滤进程id：

leo@localhost$ ps -ef | grep php

root 26278 1 0 2015 ? 00:00:31 /usr/local/php/bin/php /var/www/html/redis/daemon/daemon_register.php
root 26280 1 0 2015 ? 00:00:34 /usr/local/php/bin/php /var/www/html/redis/daemon/daemon_register.php

leo@localhost$ ps -ef | grep php | grep -v grep | cut -c 15-20

 26280
 26280

ps -ef 查询并过滤进程id，并杀死该进程：

leo@localhost$ ps -ef | grep php
root 26278 1 0 2015 ? 00:00:31 /usr/local/php/bin/php /var/www/html/redis/daemon/daemon_register.php  （杀死进程前）
root 26278 1 0 2015 ? 00:00:31 /usr/local/php/bin/php /var/www/html/redis/daemon/daemon_register.php
leo@localhost$ ps -ef | grep curl | grep -v php | cut -c 15-20
 28367
leo@localhost$ ps -ef | grep php | grep -v grep | cut -c 15-20 | xargs kill -9
leo@localhost$ ps -ef | grep php
root 26278 1 0 2015 ? 00:00:31 /usr/local/php/bin/php /var/www/html/redis/daemon/daemon_register.php （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

劝君一句：kill很危险，使用须谨慎。
