Thanks for the quick replies from:

All of you guy provided the information that I wanted.
My initial confusion came from the fact that I tried
to catch the output after the "&", such as:
tar xvf a_tar_file & > /tmp/log 2>&1

of course it did not work for me. The correct way of
doing this is:

tar xvf a_tar_file > /tmp/log 2>&1 &

As far as recording the PID is concerned, $! seems to
be the easiest way to go. I like Steve's way of
handling this:

scriptone.sh > /var/scriptone.$!.txt 2>&1 &
