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.
