These are probably escape sequences in your shell prompt string.
Typically they are interpreted by the terminal, like xterm, to update
title bar.

I don't think your expect worked fine to capture the desired output.

before/after makes sense only after an expect. At this point there is
only a sendline; not expect. So the above None output is expected.

1 implies it matched the second pattern. You want to use raw strings.
r'\$' or else the re sent down is a plain $ which re interprets as end
of buffer.
Most important here is your prompt doesn't end with a $ (it's
something like [EMAIL PROTECTED] ~]). Thus make it,
child.expect(r'.*]')
Try the ls command and rest of the statements.
