【问题描述】：

我正在从一个 txt 文件中读取数百个 IP 地址，想将列表 ping 到文件末尾。希望它在循环中运行，读取到文件末尾，然后再次从第一个地址开始。

trap 'echo ****Interrupted****; exit'INT

echo -n "Enter the file name with the ip addresses"
read file

echo -n "Enter the file name for the log file"
read log

while read line
do
echo "pinging: "$line
echo -e "">>$log
echo -n "NEXT PING: ">>$log
echo -n "$line" : " >>$log
$ping -c 3 -W 2 $line >>$log
done <"$file"

【问题讨论】：

用true 条件将你的while循环包裹在另一个while循环中。也许while true ; do while read line ; do ...... done < "$file" ; sleep 5 #?; done祝你好运。

使用fping。

DESCRIPTION
   fping  is  a  program  like ping(8) which uses the Internet Control Message 
   Protocol (ICMP) echo request to determine if a target host is responding.
   fping differs from ping in that you can specify any number of targets on the 
   command line, or specify a file containing the lists of targets to ping.
   Instead  of  sending  to  one target until it times out or replies, fping will
   send out a ping packet and move on to the next target in a round-robin
   fashion.
