Я новичок в использовании ожидаемого, и я искал ответ на следующий вопрос, но еще не нашел его.Я пытаюсь войти на сервер и запустить команду на этом сервере.Команда выведет текст, включая другую команду, которую я хочу выполнить, и пароль, который мне понадобится.
Например,
#!/usr/bin/expect --
<initialization of variables>
spawn ssh $user@$host
expect -re ".*sswor.*"
send "$password\r"
expect $prompt
send $command
expect magical stuff that I can use to create the next command
send $next_command
send $new_password
<more stuff>
Вывод "send $ command" выше:
-bash-3.00$ <command from send>
Log into the next device by copying and pasting the following line: ssh new-user@new-host
The password to login is: Ex17dsk5
-bash-3.00$
Теперь мне нужно взять "ssh new-user @ new-host" и "Ex17dsk5" и использовать их в $ next_command и $ new_password.Я думаю, что мне нужно использовать wait_out (X, string) для сопоставления выражений, но я не смог понять, как все это сделать.
Любая помощь с благодарностью.
РЕДАКТИРОВАТЬ: ДОПОЛНИТЕЛЬНАЯ ИНФОРМАЦИЯ ПОСЛЕ ОТВЕТА НИЖЕ
Спасибо за совет!Тем не менее, это все еще не работает, но намного ближе.Код, который я сейчас использую:
expect {
-re "Log into the remoteHost by copying and pasting the following line: ssh (.*)?\n?" {set remoteHostlogin "$expect_out(1,string)"; exp_continue}
-re "The password to login to the remoteHost is: (.*)\r\n" {set remoteHostpassword "$expect_out(1,string)"}
}
Я думал, что?сделал бы это не жадным.Однако, похоже, что он совпадает с последним \ n в буфере (см. Ниже).И поскольку он совпадает с последним \ n, wait_out (1, строка) содержит информацию о пароле, которую я пытаюсь сопоставить с ожидаемым.Код выдает следующую отладочную информацию:
