what does prompt "(%|#|\\$|%]) $" stands for
Posted by shafa.fahad (FahaD), 18 September 2006
I understand that we use set prompt "(%|#|\\$|%]) $" to resolve the problem of expecting different prompts
But i would like to know how exactly setting %|#|\\.... to prompt works
If it is expecting any those special characters to recognize a prompt, will a output from any of the process which returns "$" affect the program?
I login to a remote machine. so after spawing ssh and entering password i will expect prompt. Once I get the prompt I execute a script which returns huge output which has "$" in it...
I would like to know, will the expect script recognize "$" as prompt and start sending the input? because i will be expecting prompt to send the next statement....
If It will not get affected, I am pleased to hear the reason behind the same.
Thanks in advance,
Posted by admin (Graham Ellis), 18 September 2006It's looking for a string that ends with % # $ or %], followed in all cases with a single space. It does seem unlikely that you would have another process write a string ending in such a way as part of its main flow, but it's not impossible and, yes, that could cause a problem. If it can happen, you need to code for it.
