expect相关文档¶

最简单示例:

#!/usr/bin/expect
set password "your_password"
spawn ssh user@host
expect "password:"
send "$password\r"
interact

#!/usr/bin/expect
set timeout 30    # set timeout 30秒,timeout -1 为永不超时
spawn ssh -l username 192.168.1.1  # 给ssh运行进程加个壳，用来传递交互指令
expect "password:"  # 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，否等待前面设置的30秒后返回
send "ispass\r"   # 执行交互动作，与手工输入密码的动作等效
interact   # 执行完成后保持交互状态，把控制权交给控制台


$argv # 参数数组,使用$argv [n]获得, n从0开始

一个简单的实例:

#!/usr/bin/expect -f

spawn ssh zhaoweiguo@<domain>
expect "zhaoweiguo@<domain>*"

send "W1MiGN6QHe1wXoV2\r"
#expect "nst*"
sleep 0.2


send "ssh -o StrictHostKeyChecking=no zhaoweiguo@bw-vm\r"
#expect "zhaoweiguo@bw-vm*"
expect "Password*"
send "<password>\r"

#sleep 0.2
#expect "hostname:*"
#send "$host\r"

interact
