reading stdin

I want to read stdin and put it in array foo, but I don't want to bring up the prompt if stdin is empty, like

read -a foo

does. If "-t 0" is passed to read, then it doesn't put stdin into $foo when there's actually something in stdin.

I found a way:

if ! [ -t 0 ]; then

        read -a foo

fi
