使用 do while 循环的 bash 脚本无限执行

Question

下面是 bash 脚本。它无限执行。我只想为 10 台服务器执行该脚本，我已将其存储在servers.txt 文件中。请帮忙

#!/bin/bash
user=$1
pass=$2

if [ "$#" -ne 2 ];then
echo "Please run the script with userid and password as arguments"
fi

cat servers.txt | while read host

do {

 ./sandy_try.sh $user $host $pass


} < /dev/null; done

Answer 1

我会做类似的事情

while read line; do
    echo do something fancy with "$line"
done < servers.txt
