复制代码 代码如下:

#! /bin/sh

# filename killcpu.sh

if [ $# != 1 ] ; then

echo "USAGE: $0 <CPUs>"

exit 1;

fi

for i in `seq $1`

do

echo -ne "

i=0;

while true

do

i=i+1;

done" | /bin/sh &

pid_array[$i]=$! ;

done

for i in "${pid_array[@]}"; do

echo 'kill ' $i ';';

done

使用方法很简单，参数3表示消耗3颗CPU的资源，运行后，会有一堆 kill 命令，方便 kill 进程：

复制代码 代码如下:

[root@test02 ~]# ./killcpu.sh 3

kill 30104 ;

kill 30106 ;

kill 30108 ;

[root@test02 ~]# top
