expect 远程访问机器并执行命令

标签：new   需要   tin   print   mod   otp   roo   远程   lang   

代码如下：

#!/bin/bash
LANG=en
user="lv"

command1="touch a.txt"
command2="chmod 777 a.txt"
command3="cp a.txt b.txt"

for line in `cat ip.list`;do

ip=`echo $line |awk -F "," ‘{print $1}‘`
common_passwd=`echo $line |awk -F "," ‘{print $2}‘`
new_rootpasswd=`echo $line |awk -F "," ‘{print $3}‘` 

/usr/bin/expect << EOF
set time 30
spawn ssh $user@$ip

expect {
"yes/no" { send "yes\r";exp_continue}
"password:" { send "$common_passwd\r"}
}

expect "]*"
send "su -\r"

expect {
"Password:" { send "$new_rootpasswd\r"}
}
expect "]*"
send "$command1\r"
expect "]*"
send "$command2\r"
expect "]*" 
send "$command3\r"

expect "]*"
send "exit\r"
EOF

done

ip.list 文本内容如下：

192.168.245.129,zhou2,Lg2=0.301!@#,
192.168.245.130,zhou3,e=2.71828!@#,

脚本执行结果如下：
