\\\\\\\\\\\\\\///////////////

一、cat autorun.sh
#!/bin/bash

# ssh登入用户名，请修改为目标用户名，等号两边不能空格

# ssh登入密码，请修改为目标用户密码，等号两边不能空格

127.0.0.1

for ip in ${ips[@]} ; do

# 执行自动交互脚本，传入用户名、密码、IP作为参数
# 后台执行，多进程并行执行
./ssh.sh $user $passwd $ip &

# 显示部分放在后面是为了后运行结果，不用再shell窗口中去翻页查看
echo
echo   "-----------------------------------------------------"
printf "|        ip = %-15s     NO. = %03d         |\n" $ip $count

puts "USAGE:"
puts "\t ./ssh.sh <username> <passwd> <host_ip>"

exit -1
}

# 设置等待延时时间

# 获取ssh连接的用户名
set ssh_user [lindex $argv 0]
# 获取ssh连接的密码
set password [lindex $argv 1]
# 获取ssh连接的IP

# 读取命令文件，每一行一条命令
set infile    [open "./commands" r]
set file_data [read $infile]
set cmds      [split $file_data "\n"]

# 显示读取到的指令
puts "show commands:"
foreach {cmd} $cmds {
puts "\t$cmd"
}

# ssh远程连接到目标机器
spawn ssh ${ssh_user}@${host_ip}
expect {
"*yes/no"    { send "yes\r"; exp_continue }
"?assword:*" { send "${password}\r" }
}

# 延时500毫秒，再继续运行
#after 500

# 等待目标返回，并跳转到目标机的根目录
expect "\."
send "cd / \r"

# for循环执行目标指令
foreach {cmd} $cmds {
expect "\."
send "${cmd} \r"
}

# 退出远程连接
expect "\."
send "exit \r"

# 等待远程结束
expect eof

三、cat commands
ls -al
pwd
