This cannot be right. The other program's prompt is never deleted when i use read -p ' ', I can only erase until the point where readline printed that space. This means that readline _does_ know where to stop, right? This is what I consider the "correct" behaviour. Is there any way to achieve this without printing additional characters to the screen? > The second is that you're going to > be able to drive an arbitrary program via a pipe -- the key to rlwrap's > working is that it allocates and uses a pty. I don't want to write a pty in bash, I just want readline to stop where it printed the 'empty prompt' when I use read -e -p '' (which would be good enough for most cli programs). To summarize: Please explain why using read -e -p ' ' the other program's prompt won't be deleted, but it will if i use read -e -p '' --- xoxo iza
