Bash scripting and while loop piping

[davidbrit2]

How can I send the output of a command to a while loop. I can do so with a file doing this:

while command
do
something
done < /tmp/foo

Is this what you are looking for:

cat /etc/hosts | while read foo; do echo $foo; done

Hmm, I could have sworn I tried something like that, but maybe I'll play around with that setup again.
