脚本：通过ssh、scp和expect批量复制文件到其它设备，已解决传输文件不完整的问题

一、简单示例

remoteUser=
remotepassword=
localFiles=test.txt
remoteDir=/home/nvidia/Downloads/

for line in $(cat ip.txt)
do
expect <<EOF
set timeout -1
spawn scp -r ${localFiles} ${remoteUser}@${line}:${remoteDir}
expect {
	"yes/no" {send "yes\r"; exp_continue}
	"password:" {send "${password}\r"}
}
expect 100%
expect eof
EOF
  if [ $? -eq 0 ]; then
    echo "${line}成功"
  else
    echo "${line}失败"
  fi
done

二、实际应用（cpFilesToRemoteNodes.sh）

• 特点：
  加入了ping IP的操作，避免连接超时消耗太多时间的问题
  网络不好的时候，也能传输文件100%
  能够返回传输成功和失败的设备ip

• 使用步骤如下：
  1、使用vi创建一个关于ip.txt文件，并填写或粘贴ip到文件里
  

2、执行脚本

3、效果

4、脚本内容（cpFilesToRemoteNodes.sh）
