The flag bits keep changing over time, but the original list of states shown by "ps" has always been: crash> help ps ... 5. the task state (RU, IN, UN, ZO, ST, DE, SW). ... However I agree with you that for clarity's sake the traced state should be differentiated. But I think it would be better to change it to "TR" instead of your "TS" suggestion -- note that the verbose translation used by the "set" command shows "TASK_TRACED": if (state & _TRACING_STOPPED_) sprintf(&buf[strlen(buf)], "%sTASK_TRACED", count++ ? "|" : ""); I'll update the "ps" help page with the new "TR" identifier. Thanks, Dave
