Regex Expect：使用远程命令的输出
我不熟悉使用expect，我已经搜索了以下问题的答案，但还没有找到。我正在尝试登录到服务器并在该服务器上运行命令。该命令将输出文本，包括我要运行的另一个命令和我需要的密码 例如 我的想法是什么？会让它不贪婪。但是，它似乎与缓冲区中的最后一个\n匹配（请参见下文）。由于它与最后一个\n匹配，expect\u out（1，字符串）包含我试图与expect匹配的密码信息。该代码生成以下调试信息：Regex Expect：使用远程命令的输出,regex,command,send,expect,Regex,Command,Send,Expect,我不熟悉使用expect，我已经搜索了以下问题的答案，但还没有找到。我正在尝试登录到服务器并在该服务器上运行命令。该命令将输出文本，包括我要运行的另一个命令和我需要的密码 例如 我的想法是什么？会让它不贪婪。但是，它似乎与缓冲区中的最后一个\n匹配（请参见下文）。由于它与最后一个\n匹配，expect\u out（1，字符串）包含我试图与expect匹配的密码信息。该代码生成以下调试信息： You must ssh to the remoteHost from one of the log se

编辑 谢谢你们的帮助！以下是我最终决定匹配的内容： :
试试看。还可以在脚本中使用

set loginstr "$expect_out(1,string)" }
expect -re "The password to login is: (.*)\n" {

send "$loginstr\r"
expect "*?assword*"
send "$passwordstr\r"
我还不能完全测试这个，但它看起来很有希望。早上我应该能够验证这是否有效。谢谢谢谢你的提示。这不是很有效，我想这是因为其中一个模式是贪婪匹配，但我还没有弄清楚如何纠正它。如果您能看一下上面帖子中添加的信息，我将不胜感激。为了使其不贪婪，您需要将
