For 2023 - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Expect prompt

Posted by shafa.fahad (FahaD), 20 September 2006


I am using set prompt "(%|#|\\$|%]) $" to expect prompts as

expect -re $prompt
send "$command\r"

The anove expect works for prompts like

FahaDs:~/mywork fahad$

But the script does not recognize the prompt, when the prompt is like

nsmail@eng-mail01 (/home/nsmail):

Please help me how to expect recognize the above prompt.

Your best bet is to work our what's unique to that prompt that won't occur in the general text, and add it in to the regular expression as another "or" (piped) option.

Regular expressions are quite an art ... perhaps you'd like to join us in 15th October when we're running a public course on Regular Expressions.
