linux批量处理脚本

1. 批量Kill

ps -ef | grep java| grep -v grep | awk '{print $2}'| xargs kill -9

2. 统计进程数

ps -ef| grep java | grep -v grep | awk '{print $2}'| wc

3. 批量打开防火墙端口

#!/bin/sh
ports=$1
echo "$ports"
IFS=' '
read -ra ports_array <<< "$ports"
for i in "${ports_array[@]}"
do
  echo "Open iptable port:$i"
  firewall-cmd --zone=public --add-port=$i/tcp --permanent
done

systemctl stop firewalld
systemctl start firewalld

echo "OK!"
