TRACE-CMD-START(1)				      libtracefs Manual					  TRACE-CMD-START(1)

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

SYNOPSIS
       trace-cmd start [OPTIONS]

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).

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.
