linux單點登入shell

標籤：

網上查了很多,沒有效果,自己寫了一個,雖然有點次,但是功能還是能實現了.廢話少說,看shell

#!/bin/shfunction main { lines=`ps -eo user,pid,cmd | grep -v root |grep sshd`;tmp=0;array=();for i in ${lines[*]}doif [ $(($tmp%4)) -eq 0 -o $(($tmp%4)) -eq 1 ]thenarray=(${array[@]} $i);fitmp=$(($tmp+1));donefor i in ${array[*]}dotmp=0;for((j=0;j< ${#array[*]};++j))dop=${array[$j]};if [ "$i" == "$p" ]thentmp=$(($tmp+1));fiif [ $tmp -eq 2 ]thenp=${array[$(($j+1))]};kstr=`kill -9 $p`;echo $kstr;break;fidonedone}while [ 2 -ge 1 ]domain;sleep 2;done
