如何編寫第一個命令後輸入密碼的bash腳本？

可能重複：
Using expect to pass a password to ssh

我希望有一臺遠程機器和而不是與機器地址和密碼一起使用ssh命令ssh連接，我只想寫一個這個小函數執行ssh命令到機器並在服務器詢問之後進入傳遞。我可以寫ssh部分，但是我怎麼能讓主機要求的時候進入的腳本呢？

Answer 1

您可以使用expect腳本。您可以從cmd行傳遞參數。我寫的示例代碼：

#!/usr/bin/expect 

set timeout 100 
set host [lindex $argv 0] 
set username [lindex $argv 1] 
set password [lindex $argv 2] 
set command [lindex $argv 3] 

spawn ssh $username@$host $command 
#puts $command 
expect { 
    "(yes/no)?" 
     { 
      send "yes\n" 
      expect "*assword:" { send "$password\n"} 
     } 
    "*assword:" 
     { 
      send "$password\n" 
     } 
    } 

Answer 2

您可以使用Expect tool
這是你需要的東西：

編輯

#!/usr/bin/expect 
set timeout 60 
set user "yourName" 
set machine "nameOfYourMachine" 
set password "yourPassword" 
set command "command that you want execute via ssh" 
spawn ssh $user@$machine 
while {1} { 
expect { 
     eof       {break} 
     "The authenticity of host" {send "yes\r"} 
     "password:"     {send "$password\r"} 
     "*\]"      {send "exit\r"} 
     "bash"      {send "$command"} 
} 
} 
wait 
close $spawn_id 

就變通辦法，因爲你需要
