linux - else 字符串匹配在 expect 中

Question

我想对 telnet 使用 expect 发送命令后 它可能会返回不同的结果 让我说，像以下3种可能性

1 successful
2 normal
3 there are something wrong...blabla
  you can refer to ....blabla


expect{
   "successful" {}
   "normal" {} 
   #here, for the third possibility, I want to use something like "else", so what should I put here? thanks!
}

Answer 1

您要查找的关键字是default。

expect{
   "successful" {}
   "normal" {} 
   default {}
}
