远程批量获取Linux主机操作系统版本

脚本执行前提：

1.拷贝check_snmp到脚本执行的主机中或在此主机中安装nagios;

2.保持list.txt中只有一个IP列

执行脚本如下：

#!/bin/bash
#echo "">list_os.txt
\cp list.txt list_1.txt
awk {'print $1'} list.txt |while read line
do
echo $line
info=`/usr/local/nagios/libexec/check_snmp -H  $line  -C jd -o sysDescr.0`
centos63=`echo $info | grep 2.6.32-279`
centos62=`echo $info | grep 2.6.32-220`
centos56=`echo $info | grep 2.6.18-238`
if [ -n "$centos63" ];then
echo "centos63"
sed -i "s/^$line$/$line\tCentOS6.3/g" list_1.txt
fi
if [ -n "$centos62" ];then
echo "centos62"
sed -i "s/^$line$/$line\tCentOS6.2/g" list_1.txt
fi
if [ -n "$centos56" ];then
echo "centos56"
sed -i "s/^$line$/$line\tCentOS5.6/g" list_1.txt
fi

echo "---------"
done
