94 | delete trace : delete one or more tracepoints. | |

98 | passcount : specify a pass count for a tracepoint. | |
99 | tstart : start a trace experiment. | |
100 | tstop : stop a trace experiment. | |
101 | tstatus : query the status of a trace experiment. | |
102 | tfind : find a trace frame in the trace buffer. | |
103 | tdump : print everything collected at the current tracepoint. | |
104 | save-tracepoints : write tracepoint setup into a file. | |

109 | $trace_file : source file of trace frame currently being debugged. | |
