   trace-cmd-start    ( 1 )

---

Имя (Name)

trace-cmd-start - start the Ftrace Linux kernel tracer without recording

---

Синопсис (Synopsis)

trace-cmd start [OPTIONS]

---

Описание (Description)

The trace-cmd(1) start enables all the Ftrace tracing the same way trace-cmd-record(1) does. The difference is that it does not run threads to create a trace.dat file. This is useful just to enable Ftrace and you are only interested in the trace after some event has occurred and the trace is stopped. Then the trace can be read straight from the Ftrace pseudo file system or can be extracted with trace-cmd-extract(1).

Параметры (Options)

The options are the same as trace-cmd-record(1), except that it
       does not take options specific to recording (-s, -o, -N, and -t).

       --fork
           This option is only available for trace-cmd start. It tells
           trace-cmd to not wait for the process to finish before
           returning. With this option, trace-cmd start will return
           right after it forks the process on the command line. This
           option only has an effect if trace-cmd start also executes a
           command.
