1、如果是字符型，直接输出：xx.xx.xx.xx  is Down
2、如果是数字型，判断值如果 大于等于“-10000” and 小于等于“10000” 输出：xx.xx.xx is Good
3、如果是数字型，判断值如果 小于“-10000” or 大于“10000” 输出：xx.xx.xx is Delay

谢谢！OK

还有个问题咨询下

if [ -n "$(echo $1| sed -n "/^[0-9]\+$/p")" ];then
echo "$1 is number."
else
echo 'no.'
fi
中的转义符\ 在什么时候用，为什么\用在+前面。

$ echo 123 | sed -n "/^[0-9]\+$/p"

$ echo 123 | sed -rn "/^[0-9]+$/p"
