Full Discussion: Array with do while and if loop

Because you're in the middle of a pipe chain, standard input is already being used. Your read just grabs the next line printed by awk!

You should tell it explicitly that you want to read from the terminal, like

Code:
read response < /dev/tty

/dev/tty is a special file that is always your current terminal.

Simplifying it like vgersh99 suggests is also a good idea. Reducing the number of things in your pipe chain will make your script much more efficient.
