Ping随机IP以查看是否存在&ŧ039；的连接

Posted 2021-02-27

One that just checks a random IP on the internet to see if we have internet access:
Code:	
 
shopt -s extglob
GW=216.239.32.10
IFS=''
PING=`ping -c1 -n -t5 -o $GW`
RC=$?
if [ $RC -eq 2 ]; then
   echo "Internet ($GW) no reply"
   exit 1
fi
RT=$( echo $PING | head -n2 | tail -n1 | awk -F= '{print $4}' )
echo "Internet ($GW) $RT"
exit $RC
