我的博客已迁移到xdoujiang.com请去那边和我交流cat ip.sh

set -o nounset
ipfile="/root/iplist"
[[ -e $ipfile ]] || exit 1
pingdir="/opt/$(date +%Y%m%d)"
pinglog=${pingdir}/ping
pinglog2=${pingdir}/$(date +%s)ping
function pingfc ()
{
[[ -d ${pingdir} ]] || mkdir -p ${pingdir}
[[ -e $pinglog ]] && `> $pinglog`
[[ ! -e $pinglog ]] && touch $pinglog
i=1
while read ipline
do
(
packet=`ping -s 100 -c 100 -q $ipline|awk /transmitted/|awk '{print $6}'`
echo "$ipline $packet" >> $pinglog
)&
[[ $i%10 -eq 0 ]] && wait
done < $ipfile
wait
cat $pinglog|sort -rnk2 -t " " > $pinglog2 2>&1
}
function main ()
{
while true
do
pingfc
sleep 60
done
}
main
exit 0

bash ip.sh
执行结果
cat ping.log
111.111.111.111 100%
222.222.222.222 100%
333.333.333.333 23%
444.444.444.444 18%
555.555.555.555 17%
666.666.666.666 14%
777.777.777.777 13%
888.888.888.888 13%
999.999.999.999 12%
cat iplist.txt
111.111.111.111
222.222.222.222
333.333.333.333
444.444.444.444
555.555.555.555
666.666.666.666
777.777.777.777

-s 字节数指定发送的数据字节数预设值是56加上8字节的ICMP头一共是64ICMP数据字节。
Specifies the number of data bytes to be sent.The default is 56, which translates into 64 ICMP data bytes when combined with the 8 bytes of ICMP header data.
-c 数目在发送指定数目的包后停止。
-c count
Stop after sending count ECHO_REQUEST packets. With deadline option, ping waits for count ECHO_REPLY packets, until the timeout expires.
-q 不显示任何传送封包的信息只显示最后的结果。
-q Quiet output.Nothing is displayed except the summary lines at startup time and when finished.
二、需要安装fping命令(apt-get -y install fping --force-yes或yum -y install fping)
fping - sends ICMP ECHO_REQUEST packets to network hosts
fping -ef /root/iplist.txt >ping.log 2>&1

执行结果
cat ping.log
10.1.1.101 is alive (0.66 ms)
10.1.1.102 is alive (1.22 ms)
10.1.1.104 is alive (1.28 ms)
10.1.1.105 is alive (1.26 ms)
10.1.1.103 is unreachable
cat iplist.txt
10.1.1.101
10.1.1.102
10.1.1.103
10.1.1.104
10.1.1.105
-f Read list of targets from a file.
-e Show elapsed (round-trip) time of packets
