<pre>
cat main 
#!/bin/bash
for ip   in `cat list` 

do 
#echo $ip
./addkey  $ip

done 



cat addkey 
#!/usr/local/bin/expect
 #define var

set password "P2xMGipLpSG7dA=="


#spawn
spawn ssh-copy-id  -i /home/evan/lx/ssh/opspub root@$host
#spawn ssh-copy-id  -i /home/evan/.ssh/id_rsa.pub root@$host
#ssh-copy-id  -i /home/evan/.ssh/id_rsa.pub root@121.41.101.200

#expect
expect {                  
 "*yes/no" { send "yes\r"; exp_continue}   
 "*password:" { send "$password\r" }       
 }  
#send  "exit\r"  
expect eof

cat list 
192.168.7.4
192.168.7.46

##上面用了copy-id  如果想用scp  etc 

    #!/usr/bin/expect    
    set timeout 5    
    set hostno [lindex $argv 0]    
    spawn scp ~/.ssh/id_dsa.pub impala$hostno:~/.ssh/pub_key    
    expect "*password*"    
    send "111111\r"    
    spawn ssh impala$hostno "cat ~/.ssh/pub_key/ >> ~/.ssh/authorized_keys"    
    expect "*password*"    
    send "111111\r"    
    spawn ssh impala$hostno "chmod 600 ~/.ssh/authorized_keys"    
    expect "*password*"    
    send "111111\r"    
    expect eof    

（3）分析：
set可以设置超时，或者设置一个变量的值
spawn是执行一个命令
expect等待一个匹配的输出流中的内容
send是匹配到之后向输入流写入的内容
[lindex $argv 0]表示脚本的第0个参数
expect eof表示读取到文件结束符
