| 10.3.1.174 | 22 |
| 10.3.1.212 | 2222 |
+------------+------+
循环获取IP和PORT#!/bin/bash
tmp=`mysql -Ne "SELECT ip,port FROM op.host WHERE os='linux' and type='支持'"|while read a b;do echo "$a:$b";done`
for i in $tmp
do
ip=`echo $i |cut -d: -f 1`
port=`echo $i |cut -d: -f 2`
echo "ip:$ip,port:$port"
done
结果为：ip:10.3.1.155,port:22
ip:10.3.1.156,port:22
ip:10.3.1.174,port:22
ip:10.3.1.212,port:2222
