虚拟机练习用expect批量分发ssh公钥出现的：

1. #!/usr/bin/expect
   
2. if { $argc != 2 } {
   
3.         send_user "Usage:expect usage.exp UserName IPdress\n"
   
4.         exit
   
5. }
   
6. 
   
7. set username [lindex $argv 0]
   
8. set ip [lindex $argv 1]
   
9. set password "123456"
   
10. 
    
11. spawn ssh-copy-id -i ~/.ssh/id_dsa.pub $username@$ip
    
12. 
    
13. set timeout 10
    
14. expect {
    
15.         "yes/no"        {send "yes\r";exp_continue}
    
16.         "*password"        {send "$password\r"}
    
17. }
    
18. expect eof
    
19. exit
