Ввод данных luks pexpect?

Question

[username]

почему не вводит пароли с помощью pexpect модуля, хотя с другими командами не замечал проблем? (например, passwd)

luks_part = check_output("blkid | grep -v swap | grep crypto_LUKS | awk '{print $1}' | sed -e s/://g", shell=True).decode('utf-8')
luks_part = re.sub("\n",'',luks_part)
pass_for_luks_5 = pexpect.spawn(f'sudo cryptsetup luksAddKey -S5 {luks_part}')
pass_for_luks_5.expect('Enter any existing passphrase:')
pass_for_luks_5.sendline(KEY1)
pass_for_luks_5.expect('Enter new passphrase for key slot:')
pass_for_luks_5.sendline(KEY2)

По итогу пустой ввод. Возможно стоит использовать другой подход?

Почитайте про передачу pexpect специальных символов. Мне думается, это ваш случай.

pass_for_luks_5 = pexpect.spawn(f'sudo cryptsetup luksAddKey -S2 "{luks_part}"',encoding='utf-8')
pass_for_luks_5.expect(['Enter any existing passphrase: ',pexpect.EOF])
pass_for_luks_5.sendline(KEY1)
print(pass_for_luks_5.before)
print(pass_for_luks_5.after)
pass_for_luks_5.expect('Enter new passphrase for key slot: ')
pass_for_luks_5.sendline(KEY2)
print(pass_for_luks_5.before)
print(pass_for_luks_5.after)
pass_for_luks_5.expect('Verify passphrase: ')
pass_for_luks_5.sendline(KEY2)
print(pass_for_luks_5.before)
print(pass_for_luks_5.after)

Ответ тот же, с пустыми паролями :

Enter any existing passphrase: 

Enter new passphrase for key slot: 

Verify passphrase:
