Using read -p in a bash script that was executed from pipe

Question

I apologize in advance - I don\'t fully understand the ideas behind what I\'m asking well enough to understand why it\'s not working (I don\'t know what I need to le

Answer 1

The tty solution works. Test it with this code, for example:

$ date | { read -p "Echo date? " r 

The prompt from read appears on the terminal and read waits for a response before deciding to echo the date or not.

What I wrote above differs from the line below in two key aspects:

read -t 1 __response 

First, the option -t 1 gives read a timeout of one second. Secondly, this command does not provide a prompt. The combination of these two probably means that, even though read was briefly asking for input, you didn't know it.
