How to write bash script that enters password after the first command?

可能的重复：
使用 expect 将密码传递给 ssh
I want to have ssh connection to a remote machine and instead of using ssh command along with the machine address and password, I just want to write a little function that executes the ssh command to the machine and enters the pass after the server asks it. I can write the ssh part but how can I make the script that enters also the pass when the host ask for it?
我想与远程机器建立 ssh 连接，而不是使用 ssh 命令以及机器地址和密码，我只想编写一个小函数，该函数对机器执行 ssh 命令并在服务器询问后输入通行证。我可以写ssh部分，但是当主机要求它时，我如何制作进入的脚本？

You may use expectscript. You can pass arguments from cmd line. Sample code I write:
您可以使用expect脚本。您可以从 cmd 行传递参数。我写的示例代码：
#!/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"
}
}

它正是您所需要的：Expect tool

编辑
#!/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
Just workaround it as you need
只需根据需要解决它
