断掉服务器上其他用户的连接

前提是需要获取非法登录用户的IP，并作为参数传给脚本

#!/bin/bash
if [ -z $1 ]
then
   echo "`basename $0` enter error!"
fi
host_name=`who | grep "$1" | awk '{print $2}'`
pid=`ps aux | grep "$host_name" | grep "bash" | awk '{print $2}'`
echo $pid | tee pid
sed 's/ /\n/gw pid_file' pid
while read LINE
do
  kill -9  $LINE
done < pid_file

#count=`awk '{print NF}' pid`
#echo $count

#kill -9 $pid
