bash是通过$0 ... $n接收参数
expect是通过set <变量名称> [lindex $argv <param index>]
例如：set username [lindex $argv 0]
#!/usr/bin/expect
set timeout 10
set username [lindex $argv 0]
set password [lindex $argv 1]
set hostname [lindex $argv 2]
spawn ssh $username@$hostname
expect "yes/no"
send "yes\r"
expect "password:"
send "$password\r"
expect eof
执行脚本./ssh.exp root pasword hostname1
一个比较粗糙的 Linux expect 通过 telnet console 口配置网络设备
#!/bin/bash
PORT=$1
cmd="""sys\r
interface g1/1\r
ip add 1.1.1.1 24\r"""
# 执行 expect
# 每个 expect 的判断间隔为 5 秒，确保命令可以正常退出
# expect 可以通过发送 ascii 码来执行键盘组合
expect <<END
set timeout 5
spawn telnet 10.0.0.1 1111
expect "*]'" { send "\r" }
expect "*assword:" { send "P@ssword\r" }
expect {
"*>" { send "screen disable\r" }
"*]" { send "screen disable\r" }
}
expect {
"*>" { send "$cmd" }
"*]" { send "$cmd" }
}
expect "*]" { send "\03" }
expect eof
END
一个自动登录脚本
#!/usr/bin/expect
set LOGIN_IP [lindex $argv 0]
spawn zssh administrator@$LOGIN_IP -p 2222
expect {
"*yes/no*"
{send "yes\r";exp_continue;}
"*password:"
{send "password\r;"}
}
expect "ac>"
send "loginto\r"
expect "*password:"
send "password\r"
expect "*:~#"
send "cd /usr/local/\r"
