Consider the following command in Unix:

echo 0123456789 | cat >/tmp/foo &> /tmp/bar

The echo is sent to /tmp/bar.

However, what I really want is to redirect the stdout and stderr output of the cat command and not take its input.

What is the proper syntax to do this?

echo 0123456789 | (cat >/tmp/foo) &> /tmp/bar
