这不格式不好控制嘛，再说整理成一个文档，也方便多年以后检索，总是比在一个回复中找到内容来的容易些。
果然格式很难弄，找到一个取巧的办法，用代码格式，原样过来，哈哈。
回复 88# 无风之谷 - 前言
- 为了参与[url]http://bbs.chinaunix.net/thread-3757201-9-1.html[/url]的这个讨论，整理一下以前写的脚本。现在看来，这个脚本写的很简陋，并发操作也只是分批的控制而不是完全的并行，不过工作起来还算简单稳定。
- 概述
- 此脚本使用 expect 来对需要交互输入用户名和密码等操作进行自动化，并有对于主机提示自动加入信任列表、操作失败记录日志等功能。
- 正文
- 这个脚本分三个文件，逐一附录如下：
- 1. 主脚本：batch_ssh.sh
- 1. #!/bin/bash
- 2. # batch_scp.sh
