消耗CPU和内存的脚本

用法

./shell.sh 4 (4为4内核)

查看cpu内核数量 > lscpu

执行后会出现一堆kill命令，方便kill掉进程

 #!/bin/bash
 endless_loop()
 {
 echo -ne "i=0;
 while true
 do
 i=i+100;
 i=100done" | /bin/bash &
 }
 if [ $# != 1 ]; then
 echo "USAGE: $0 "
 exit 1;
 fi

 for i in `seq $1`
 do
 endless_loop
 pid_array[$i]=$!;
 done

 for i in "${pid_array[@]}"; do
 echo 'kill' $i ';';
 done
