TRACE-CMD-START(1)                                    TRACE-CMD-START(1)

NAME         top

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

SYNOPSIS         top

       trace-cmd start [OPTIONS]

DESCRIPTION         top

       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).

OPTIONS         top

       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).

           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
