This is very insightful! This may be a bit naive on my end given that I haven't provided much serious thought on this, but would it be possible to include some kind of conditional statement that asserts something like 'if the user-inputted prompt is in the first line and it is proceeded by testpmd>, then remove the first line,' or something along those lines? I personally can't think of a reason that justifies leaving the command prompt in the output. Although the weight of my input on this is admittedly very light since I don't have a good intuition about this issue. <snip>
