This week, we're updating our course layouts and descriptions. Presentation and materials always gently change over time, but just occasionally there's a need to make a step change to clear out some of the old and roll in the new. That's now happening - but over a long and complex site it's not instant and you'll see sections of the site changing up to and including 19th September.

Expect: Reading i/p without waiting for [Enter]

In Expect, how can we read a data entered by user without waiting for a Enter key from the keyboard

Posted by admin (Graham Ellis), 3 May 2006
It all depends on the buffering of your operating system .... the issue you have come across is that the operating system typically doesn't send text typed in from the shell to expect until a new line is enetered.   That's done to give you a chance to correct typing errors.

Say, for example, that you were asked to enter your age and you entered 7 backspace 6 2 [enter] - you're 62 but you typed a seven by mistake; you do NOT want expect to act on the 7 nor have to clean up, do you?

In exceptional circumstances, you may want to bypass the buffering .... how to do that depends on the operating system you're running, whether you're running through a windows system, etc - not something I can give you a generic answer to based on what you've told us, I'm afraid
