Dear Leonard,
$ns trace-all generally generates complete information in the trace file. Unfortunately, you usually don't need most of it. A better way is not to use it. If you are interested in for example if you are interested in how seq. no. of TCP changes, you may use $tcp trace t_seqno_ Another way is to print out your own text by modifying C++ source code (e.g., using cout).
