标签:ast creat set script 请求 lin argv exit sleep
-c | 执行脚本前先执行的命令,可多次使用。 |
-d | debug模式,可以在运行时输出一些诊断信息,与在脚本开始处使用exp_internal 1相似。 |
-D | 启用交换调式器,可设一整数参数。 |
-f | 从文件读取命令,仅用于使用#!时。如果文件名为"-",则从stdin读取(使用"./-"从文件名为-的文件读取)。 |
-i | 交互式输入命令,使用"exit"或"EOF"退出输入状态。 |
-- | 标示选项结束(如果你需要传递与expect选项相似的参数给脚本时),可放到#!行:#!/usr/bin/expect --。 |
-v | 显示expect版本信息。 |
# 命令行参数
# $argv,参数数组,使用[lindex $argv n]获取,$argv 0为脚本名字
# $argc,参数个数
set username [lindex $argv 1] # 获取第1个参数
set passwd [lindex $argv 2] # 获取第2个参数
set timeout 30 # 设置超时
# spawn是expect内部命令,开启ssh连接
spawn ssh -l username 192.168.1.1
# 判断上次输出结果里是否包含“password:”的字符串,如果有则立即返回,否则就等待一段时间(timeout)后返回
expect "password:"
# 发送内容ispass(密码、命令等)

# 发送内容给用户

# 执行完成后保持交互状态,控制权交给控制台(手工操作)。否则会完成后会退出。
